Contact Lenses for High Myopia
Understanding High Myopia and Contact Lens Challenges
High myopia generally refers to nearsightedness of -6.00 diopters or more, though some eye care professionals use a threshold of -5.00 or -8.00 diopters. At this level of prescription, distant objects appear very blurry without correction, and your reliance on glasses or contact lenses is significant. When myopia exceeds -10.00 diopters, we often call it extreme or very high myopia, and special lens designs become even more important.
Not only does high myopia affect how you see, but it can also increase your risk of certain eye conditions over time. We monitor patients with high myopia more closely for retinal thinning, glaucoma, and cataracts. During your contact lens fittings, our eye doctor will also check the overall health of your eyes to ensure contact lens wear is safe for you.
High myopia is commonly defined as a spherical equivalent of -6.00 D or more or an axial length of 26 mm or more. High myopia is a risk factor for pathologic myopia, which involves degenerative changes such as myopic maculopathy. Your contact lens plan does not change these long-term risks, so regular dilated retinal exams remain important.
Standard soft contact lenses designed for mild to moderate prescriptions may not be available in the higher powers you need. Manufacturers produce fewer options as the prescription strength increases, which can limit your choices. Additionally, lenses made to correct high myopia tend to be thicker at the edges, and this extra thickness can affect how the lens rests on your eye. Lens movement is influenced by fit, diameter, modulus, and edge design.
- Thicker edges may reduce oxygen flow to your cornea
- Minus-power soft lenses are thinner in the center and thicker at the edge, which can affect peripheral corneal oxygen
- Thicker edge profiles can interact with the eyelids and may increase movement or decentration
- Higher powers can create more optical aberrations if not properly centered
- Lens movement and centration become more critical for clear vision
Wearing contact lenses that do not match your exact prescription can cause persistent blurry vision, headaches, and eye strain. For high myopia, even a small error in power can make daily activities like driving or reading difficult. If the lens fit is poor, the lens may slide around on your eye or fail to center properly, further reducing visual clarity.
Beyond poor vision, an ill-fitting lens can lead to corneal irritation, red eyes, and increased risk of infection. A lens that moves excessively can scratch the corneal surface, while one that is too tight can restrict oxygen and lead to swelling. We always recommend a professional fitting to avoid these complications and ensure your lenses work safely with your unique eye shape.
Before we recommend contact lenses for high myopia, our eye doctor evaluates your overall eye health and any underlying conditions. Chronic dry eye, allergies, or a history of recurring eye infections may require special lens materials or more frequent replacement schedules. Conditions like keratoconus or corneal scarring might make rigid lenses a better choice than soft lenses.
Your lifestyle and daily habits also play a role in lens selection. If you work long hours at a computer, you may need a lens design that maintains moisture throughout the day. If you have an active outdoor lifestyle, lenses that stay securely in place during movement become a priority. We take all of these factors into account to find the safest and most comfortable option for you.
Contact Lens Options for High Myopia
Many soft contact lens brands are available in powers up to around -12.00 diopters, which can work well for people with moderate high myopia. These lenses are made from flexible, water-containing materials that conform to the shape of your cornea. They are generally easy to insert and remove, and many patients find them comfortable from the first day of wear.
- Available in daily disposable, bi-weekly, and monthly replacement schedules
- Offer good initial comfort for most wearers
- Less expensive compared to specialty lens designs
- May provide adequate vision if your prescription falls within the standard range
If you also have astigmatism, toric soft lenses are available in extended parameters. At higher cylinder powers, rotational stability becomes more critical and may limit off-the-shelf options.
When your prescription exceeds the range of standard soft lenses, we may recommend silicone hydrogel or custom, lathe-cut extended-parameter soft lenses. These designs can correct powers up to about -20.00 D or more and prioritize higher oxygen permeability and tailored thickness for comfort and centration.
Extended-parameter lenses are typically custom-ordered using your exact prescription and corneal measurements, including diameter and base curve. Lead times are longer than stock options, but the tailored fit can improve comfort and visual performance.
Rigid gas permeable lenses are made from firm, oxygen-permeable materials that maintain their shape on the eye. Because they do not flex like soft lenses, RGP lenses can provide sharper, crisper vision, especially for high prescriptions. They are particularly beneficial if you also have astigmatism or irregular corneas. With RGPs, the tear lens formed under the lens can reduce the lens power needed, which is helpful in very high prescriptions.
RGP lenses typically require a longer adaptation period than soft lenses, as the firm material can feel more noticeable on your eye at first. However, many patients find that once they adjust, RGP lenses offer superior visual clarity and can be healthier for long-term wear. These lenses are durable and can last a year or more with proper care. Replacement is individualized and may be yearly or sooner if scratches, deposits, or coating wear are present.
Scleral lenses are large-diameter rigid lenses that vault over the entire cornea and rest on the white part of the eye, called the sclera. This design creates a fluid-filled space between the lens and your cornea, which can provide exceptional comfort and stable vision. Scleral lenses are often an excellent option for very high myopia, irregular corneas, and severe dry eye.
- Minimal movement on the eye leads to consistent vision throughout the day
- The fluid reservoir keeps your cornea hydrated and comfortable
- Custom-made to match your eye's unique contours
- May be recommended when other lens types have failed or are not suitable
Important: Scleral lenses should be filled completely with non-preserved sterile saline before insertion, and bubbles should be avoided. Do not use preserved solutions in the bowl of the lens. Use DMV plungers as instructed for safe insertion and removal, and never use tap water at any step.
Hybrid contact lenses feature a rigid center zone surrounded by a soft outer skirt. This design aims to deliver the sharp optics of an RGP lens with the initial comfort of a soft lens. For patients with high myopia who struggle to adapt to traditional RGP lenses, hybrids can be a helpful compromise.
Hybrid lenses are custom-fitted and can correct a wide range of prescriptions, including high myopia and astigmatism. They require specific cleaning and handling procedures, and replacement schedules vary by brand. Our eye doctor will discuss whether hybrid lenses are appropriate for your eyes and lifestyle.
Orthokeratology involves wearing specially designed rigid lenses overnight to gently reshape the cornea. When you remove the lenses in the morning, your cornea retains the new shape temporarily, allowing you to see clearly during the day without glasses or contacts. Ortho-K is primarily used for mild to moderate myopia, and its effectiveness diminishes with higher prescriptions.
For high myopia, ortho-K may provide some correction but typically cannot eliminate the need for daytime correction entirely. Ortho-K is more commonly recommended for myopia control in children and young adults rather than as a primary solution for very high prescriptions. We may consider it in specific cases, particularly when slowing myopia progression in children or adolescents is a priority.
The Contact Lens Fitting and Evaluation Process
Every contact lens fitting begins with a thorough eye examination. Our eye doctor will check your overall eye health, screen for any conditions that might affect lens wear, and determine your exact prescription. For high myopia, even a small error in refraction can lead to poor vision, so we take extra care to measure your prescription accurately.
We use advanced equipment to test your vision at multiple distances and assess how your eyes work together. This comprehensive approach ensures that the contact lens prescription we provide will give you the clearest, most comfortable vision possible. We also discuss your visual needs, such as computer work or sports, to tailor our recommendations. For high myopia, we may also measure axial length to establish a baseline and monitor for change.
Corneal topography creates a detailed map of the shape and curvature of your cornea. This technology is especially important for high myopia fittings because it reveals subtle irregularities that can affect lens fit and vision. The topography data guides our selection of lens diameter, base curve, and design.
- Identifies areas of steep or flat curvature that require special attention
- Helps us choose between spherical, toric, or specialty lens designs
- Ensures the lens will center properly and move appropriately with each blink
- Provides a baseline for monitoring corneal health over time
- Provides data to support scleral or hybrid lens selection if soft lens centration is inadequate
Once we select an initial lens type and parameters, we place trial lenses on your eyes and allow them to settle for a few minutes. We then reassess your vision to confirm the lenses provide the clarity you need. For high myopia, we may test multiple lens powers or designs to find the combination that works best.
During the trial fitting, you will have the opportunity to experience how the lenses feel and how well you can see with them. We encourage you to ask questions and share any concerns, as your feedback helps us refine the fit. This step is critical to ensuring your long-term success and satisfaction with contact lens wear.
After placing the trial lenses, our eye doctor uses a specialized microscope called a slit lamp to observe how the lenses interact with your eyes. We look for proper movement with each blink, as too much or too little movement can indicate a fit issue. The lens should center well over your pupil to provide stable vision and avoid irritation.
Comfort is equally important, especially for lenses designed to correct high myopia. Thicker edges or larger diameters can sometimes cause awareness or discomfort, and we may adjust the lens design or switch to a different material if needed. Our goal is to find a lens that you can wear comfortably for the entire duration of your waking hours.
After your initial fitting, we schedule follow-up appointments to monitor how your eyes adapt to the new lenses. The first follow-up typically occurs within a week, allowing us to check for any signs of irritation, redness, or improper fit. For high myopia, especially with specialty lenses, additional visits may be necessary to fine-tune the prescription or fit.
- First follow-up usually within one week of lens dispensing
- Second follow-up around one month to assess longer-term comfort and vision
- Additional follow-up at about three months for scleral, hybrid, or complex toric fits
- Regular exams every 6 to 12 months, with more frequent visits for high-risk or specialty lens wear
- Additional visits if you experience discomfort, vision changes, or other concerns
Wearing and Caring for High Myopia Contact Lenses
Inserting and removing contact lenses for high myopia can be more challenging due to thicker edges or larger diameters, especially with RGP or scleral lenses. We recommend practicing in front of a well-lit mirror and using both hands to hold your eyelids open. For scleral lenses, you may need to use a small suction tool or special technique to remove the lens gently.
Always wash and dry your hands thoroughly before handling your lenses. Place the lens on the tip of your index finger and check that it is not inside out. For soft lenses, the edges should curve upward like a bowl. For rigid lenses, ensure the lens is clean and free of debris before placing it on your eye. If you struggle with insertion or removal, our eye doctor can provide hands-on training during your fitting appointments.
For scleral lenses: fill the lens completely with non-preserved sterile saline before insertion, check for bubbles, and use a DMV plunger as instructed. Never use tap water for rinsing, filling, or storing.
Proper cleaning and disinfection are essential to prevent infections and maintain clear vision. Each time you remove your lenses, rinse them with the appropriate solution and gently rub them with your fingertip to remove protein deposits and debris. Never use tap water, saliva, or any solution not approved for contact lenses, as these can introduce harmful bacteria.
- Use only the cleaning and disinfecting solutions recommended by our eye doctor
- Replace your lens case every three months to reduce contamination risk
- Follow the soaking time specified on the solution bottle to ensure complete disinfection
- Rinse lenses with fresh solution before inserting them in the morning
- Never reuse or top off old solution in your lens case
- If you use a hydrogen peroxide care system, never put peroxide directly into your eyes and do not rinse lenses with unneutralized peroxide. Allow full neutralization as directed.
- Clean and air-dry your lens case daily. Rinse with fresh disinfecting solution, wipe, and leave caps off to dry.
- For scleral lenses, use a daily surfactant cleaner and rinse with sterile saline. Fill the lens bowl only with non-preserved sterile saline before insertion.
- Use only rewetting drops labeled as safe for contact lenses. Avoid redness-relief drops while wearing lenses.
Different contact lens types have different recommended replacement schedules. Daily disposable soft lenses are discarded after a single use, which can reduce the risk of infection and eliminate the need for cleaning. Bi-weekly or monthly soft lenses must be cleaned and disinfected daily and replaced according to the schedule provided by the manufacturer.
Rigid gas permeable and scleral lenses are often replaced annually, but the timeline depends on deposits, scratches, coating wear, and comfort. We will examine the lenses at each visit and may recommend earlier replacement if needed.
It is normal to experience some awareness or mild discomfort when you first start wearing contact lenses, especially rigid or scleral designs. Your eyes need time to adapt to the presence of a lens, and the sensation usually decreases significantly within a few days to a couple of weeks. During this period, we may recommend wearing your lenses for shorter periods each day and gradually increasing the wearing time.
If discomfort persists beyond the expected adaptation period, or if you experience sharp pain, redness, or vision changes, contact our office right away. These symptoms can indicate a fit problem or an eye health issue that needs attention. Most patients find that once they are fully adapted, high myopia contact lenses become a comfortable and convenient alternative to glasses. Do not push through sharp pain, persistent redness, or reduced vision. Remove the lenses and contact us.
Even after a successful fitting, your lenses may need adjustments over time. Changes in your prescription, shifts in corneal shape, or lens-related issues like warping can all affect vision and comfort. If you notice blurry vision that does not clear with blinking, increased awareness of the lens, or redness that does not resolve, schedule an appointment with our eye doctor.
- Blurred vision that was previously clear may signal a prescription change
- Persistent discomfort can indicate an improper fit or lens damage
- Excessive lens movement or poor centration suggests a need for parameter adjustments
- Visible deposits or cloudiness on the lens surface may require a different cleaning regimen or lens replacement
- New flashes of light, a sudden increase in floaters, or a shadow or curtain in your vision require same-day evaluation to rule out a retinal tear or detachment
Potential Complications and When to Seek Care
Certain symptoms should never be ignored, as they can signal serious complications that threaten your vision. If you experience sudden vision loss, severe eye pain, intense light sensitivity, or discharge that is thick or colored, remove your contact lenses immediately and contact our office or visit an emergency room. These red flags may indicate a corneal ulcer, severe infection, or other urgent condition.
Other warning signs include seeing halos around lights, persistent redness that does not improve after removing your lenses, or a foreign body sensation that feels like something is stuck in your eye. Even if symptoms seem mild, it is better to err on the side of caution and seek professional evaluation. Early intervention can prevent complications from worsening and protect your long-term eye health. High myopes should be especially alert for new flashes, a shower of floaters, or a curtain over vision, which can signal a retinal detachment.
Your cornea needs oxygen to stay healthy, and contact lenses can reduce the amount of oxygen that reaches the corneal surface. With high myopia lenses, especially those that are thicker, the risk of oxygen deprivation increases. Over time, chronic oxygen deprivation can lead to corneal swelling, discomfort, and the growth of new blood vessels into the normally clear cornea. Silicone hydrogel soft lenses and RGP designs improve oxygen delivery, but fit and total wear time still determine real-world oxygen exposure.
We monitor for signs of oxygen deprivation during your routine follow-up visits by examining your cornea under magnification. If we detect early changes, we may recommend switching to a more breathable lens material, reducing your wearing time, or scheduling more frequent lens-free periods. Modern lens materials are designed to maximize oxygen transmission, but proper wear and care remain essential to minimize risk.
Proteins from your tear film can accumulate on contact lenses over time, creating cloudy deposits that blur your vision and irritate your eyes. High myopia lenses with thicker profiles may be more prone to buildup. Regular cleaning and timely replacement help prevent this issue, but some patients may need enzymatic cleaners or daily disposables to manage protein deposits effectively.
Allergic reactions to lens materials or care solutions can also occur, causing redness, itching, and mucus discharge. If you develop these symptoms, we may recommend switching to a preservative-free solution or a different lens material. Giant papillary conjunctivitis, an allergic response often linked to protein buildup, can develop in long-term contact lens wearers and may require a break from lens wear and treatment with anti-inflammatory eye drops. For recurrent deposits or giant papillary conjunctivitis, consider daily disposables or a hydrogen peroxide care system if appropriate.
Infections related to contact lens wear, such as bacterial or fungal keratitis, are serious but preventable complications. These infections can develop when lenses are not cleaned properly, when lenses are worn longer than recommended, or when water contaminates the lenses or case. Symptoms include severe pain, redness, blurred vision, and discharge.
- Always remove lenses before swimming, showering, or using hot tubs
- Never sleep in lenses unless specifically approved by our eye doctor for extended wear
- Replace your lens case regularly and allow it to air dry between uses
- Discard any lenses that have been contaminated by water or other non-sterile substances
- Seek immediate care if you suspect an infection, as prompt treatment is critical
- Wash and dry hands thoroughly before every insertion and removal. Avoid contact lens wear if your eyes are red or if you are unwell.
For many contact lens-related issues, calling our office during business hours is the appropriate first step. Mild discomfort, slight redness, or a lens that feels out of place can usually wait for a scheduled appointment or same-day evaluation. We can often address these concerns quickly and help you avoid more serious complications.
However, if you experience severe pain, sudden vision loss, or symptoms that worsen rapidly, do not wait for an appointment. Visit an emergency room or urgent care center that has eye care capabilities. Infections and corneal injuries can progress quickly, and early treatment is essential to preserve your vision. Always err on the side of caution when it comes to your eye health.
Frequently Asked Questions
Daily disposable lenses are available in higher powers than in the past, with some brands now offering options up to around -12.00 diopters. If your prescription falls within this range and your eyes are otherwise healthy, daily disposables can be a convenient and hygienic choice. They eliminate the need for cleaning solutions and reduce the risk of complications from poor lens hygiene, making them a popular option for many patients with high myopia. Daily toric lenses may have limited cylinder powers, so custom or monthly toric lenses may be required for higher astigmatism.
Wearing standard contact lenses does not cause your myopia to worsen more quickly. Myopia progression is influenced by genetics, age, and environmental factors like prolonged near work, rather than by the type of vision correction you use. Multifocal soft lenses and orthokeratology are used primarily for myopia control in children and adolescents, with limited effect in adults.
Dry eye symptoms can be more pronounced with thicker or less breathable contact lenses. We often recommend preservative-free lubricating eye drops that are safe for use with contact lenses throughout the day. Staying well-hydrated, taking regular breaks from screens, and using a humidifier can also help. If dryness persists, switching to a lens material with higher water content or a larger scleral lens that maintains a fluid reservoir may provide relief. Use only lubricating drops that are labeled for contact lens use and avoid vasoconstrictor redness relievers while lenses are in.
Both contact lenses and glasses have advantages and drawbacks for very high myopia. Glasses with high-minus lenses can be thick, heavy, and may create visual distortions at the edges, while contact lenses sit directly on the eye and provide a wider field of clear vision. However, contact lenses require diligent care and may not be suitable for everyone. Many patients with high myopia choose to use both options, wearing contacts during the day and switching to glasses in the evening for comfort and to give their eyes a break. Some patients with very high myopia may be candidates for implantable collamer lenses or other refractive procedures; we can discuss whether an evaluation is appropriate.
Sleeping in contact lenses, even those approved for extended wear, significantly increases the risk of eye infections and corneal complications. For high myopia, where lens thickness may already reduce oxygen flow, overnight wear can further stress the cornea. We generally recommend removing your lenses every night unless you are using orthokeratology lenses specifically designed for overnight corneal reshaping. Always follow our guidance on wear schedules to protect your eye health.
Adaptation to rigid gas permeable lenses usually takes one to two weeks, during which you may feel more aware of the lens on your eye compared to soft lenses. Scleral lenses, despite their larger size, are often more comfortable initially because they vault over the cornea and rest on the less sensitive sclera. Most patients report that discomfort decreases significantly after the first few days, and full adaptation is typically achieved within two to four weeks. We provide support and adjustments throughout this period to ensure your comfort.
