Understanding the Lifespan of Scleral Lenses
What Affects How Long Scleral Lenses Last
Most scleral lenses last between six months and two years, depending on several factors. Our eye doctor will give you a specific replacement timeline based on your lens material, wearing habits, and eye health needs.
Some patients may need replacement closer to six months, while others can safely wear their lenses for a year or longer. We monitor your lenses at regular visits to determine the right schedule for you.
Scleral lenses are made from highly oxygen-permeable materials that allow your cornea to breathe. The specific polymer we choose for your lenses affects how resistant they are to deposits, scratches, and warping over time.
Oxygen delivery depends on both material permeability and overall lens thickness, as well as the thickness of the fluid reservoir (the saline-filled space) under the lens.
Modern lens materials in 2025 offer excellent durability and clarity, but even the highest quality lenses will degrade with regular use. We select materials that balance comfort, vision quality, and longevity for your particular condition.
Lenses worn every day for long hours naturally wear out faster than lenses used part-time. The mechanical stress of daily insertion, removal, and cleaning gradually affects lens structure.
- Full-time daily wear typically shortens overall lifespan
- Occasional or part-time wear may extend how long lenses remain usable
- Your individual eye chemistry and tear composition play a major role
- Activities like swimming or dusty environments can accelerate wear
Your tears naturally contain proteins, lipids, and other substances that gradually coat your lenses. Even with excellent cleaning, microscopic deposits accumulate in the lens material itself over weeks and months.
These deposits impair lens wettability, cloud your vision, and can trigger irritation or allergic reactions. They can also harbor microbes and increase infection risk. Once deposits become embedded in the lens material, cleaning cannot remove them, and replacement becomes necessary.
Where you live and work affects how quickly your lenses age. Exposure to heat, UV light, chlorine, smoke, dust, and cosmetics all contribute to lens degradation.
- Hot climates or frequent heat exposure can warp lens materials
- UV radiation breaks down polymers over time
- Makeup, lotions, and hair products accelerate deposit formation
- Air pollution and allergens increase surface buildup
- Occupational exposures like chemicals or dust require more frequent replacement
Signs Your Scleral Lenses Need Replacement
When you first get scleral lenses, you learn what normal comfort feels like. As lenses age, you may notice you are more aware of them throughout the day, even if they do not hurt.
This increased awareness often signals that the lens surface has become rougher or that the shape has changed slightly. Both issues mean it is time to discuss replacement with our eye doctor.
- Persistent redness or impression rings that last longer than 30 minutes after removal
- Localized tenderness where the lens edge rests
- Increased need for rewetting drops or mid-day removal to maintain comfort
If your vision becomes less sharp or you notice persistent cloudiness or halos, and thorough cleaning does not restore clarity, your lenses may have permanent deposits or material changes. This is one of the most common reasons we recommend replacement. Midday fogging from tear debris or ocular surface inflammation can mimic lens breakdown. Adjusting lens fit or managing lid disease and ocular surface inflammation may be more effective than replacing the lens.
Sometimes the cloudiness comes and goes or is worse at certain times of day. Even intermittent vision problems suggest the lens material is breaking down and no longer performing as it should.
Inspect your lenses every time you clean them. Look for scratches, chips, cracks, or rough edges that could harm your eye or collect bacteria.
- Any crack or chip requires immediate replacement
- Yellow or brown discoloration indicates permanent deposits
- Warping makes the lens sit incorrectly on your eye
- Rough or irregular edges can scratch your cornea or conjunctiva (the clear tissue covering the white of your eye)
If your lenses suddenly become harder to put in or take out, the shape may have warped. A warped lens will not vault (maintain proper clearance) properly over your cornea or may suction too tightly to your eye.
If a lens feels stuck, instill several drops of sterile saline or preservative-free lubricating drops around the lens edge to break the seal, then remove with the plunger. Do not pinch the lens or squeeze your eye.
Never force a lens that does not insert or remove easily. Contact our office right away, as continuing to use a warped lens can damage your eye or trap the lens in place.
You may notice you need to remove your lenses earlier in the day than you used to because of dryness, irritation, or redness. This often happens gradually as lenses age and their surface properties change.
A significant reduction in comfortable wearing time, such as going from twelve hours to six hours, is a clear signal that replacement is needed. We can evaluate whether the lenses themselves or another eye health issue is causing the change.
Sudden severe pain, dramatic vision loss, intense light sensitivity, or heavy discharge are urgent warning signs. These symptoms may indicate an eye infection, corneal abrasion, or other serious problem rather than simple lens wear.
Remove your lenses immediately and contact our office or seek emergency eye care the same day. Do not reinsert your lenses until you are evaluated and cleared to resume wear. Do not wait for a scheduled appointment if you experience these red flag symptoms.
Caring for Your Lenses to Maximize Their Lifespan
Proper daily care is the single most important factor in extending lens life and protecting your eye health. We recommend a specific cleaning solution system designed for scleral lenses, as general contact lens solutions may not be appropriate.
- Clean lenses immediately after removal every day
- Rub each side of the lens for at least 15 seconds before rinsing and disinfecting
- Rinse with fresh solution before storing overnight
- Empty the case completely and use only fresh solution each time. Never reuse or top off old solution
- Fill your case with fresh disinfecting solution each night
- If you use a hydrogen peroxide system, always allow full neutralization before insertion. Never put peroxide solution directly in your eye or on the lens before neutralization
Unlike standard contact lenses, scleral lenses vault over your cornea and create a fluid-filled space that provides comfort and vision correction. This space must be filled with the correct sterile saline solution before you insert the lens.
- Fill the lens bowl completely with sterile, preservative-free 0.9 percent saline before insertion
- Use single-use vials or bottles labeled for ophthalmic use, or the products we recommend for scleral lens filling
- Never use tap water, multipurpose solutions, or preserved saline to fill the lens
- Check for bubbles after insertion. If you see a bubble, remove, refill with fresh saline, and reinsert
- If you feel burning on insertion, confirm you did not use hydrogen peroxide solution and that your saline is preservative-free
Always handle your lenses with clean, dry hands. Place them on a clean, lint-free surface if you need to set them down during insertion or removal.
Store lenses in a closed case filled with fresh disinfecting solution designed for rigid lenses. Keep the case closed while lenses are soaking. When empty, rinse the case with recommended solution, then air dry face down with caps off on a clean tissue. Keep the case in a clean, dry location away from bathroom sinks and humidity.
In addition to daily cleaning, we may recommend protein removal treatments to break down stubborn deposits. These treatments use enzyme-based solutions that target the proteins your tears leave behind.
Frequency is individualized based on your lens material, any surface coating, and your deposit rate. Some lenses have hydrophilic surface coatings that require compatible cleaners. Avoid enzyme or abrasive cleaners unless we recommend them for your specific lenses.
Follow our instructions precisely for any deep cleaning products, as incorrect use can damage your lenses. Some modern cleaning systems combine daily and periodic cleaning steps into one routine for convenience. In select cases, professional lab cleaning or recoating can restore surface performance and may extend lens life.
Your lens case should be replaced at least every three months, even if it looks clean. Bacterial biofilms can form inside cases and contaminate your lenses no matter how well you clean them.
- Replace your case every three months or sooner if it cracks or becomes cloudy
- Use new solution bottles before their expiration date
- Follow the manufacturer's discard-after-opening guidance for each solution
- Replace insertion and removal tools if they become damaged or hard to clean
- Replace peroxide system cases and discs as directed by the manufacturer, typically every 1 to 3 months
Certain substances and practices can quickly ruin scleral lenses or make them unsafe to wear. Never expose your lenses to tap water, saliva, or non-sterile solutions, as these can introduce dangerous microorganisms.
- Never rinse lenses with tap water or store them in water
- Do not wear lenses while swimming or in hot tubs. If accidental exposure occurs, remove lenses, clean, and fully disinfect before reinsertion
- Do not use expired solutions or solutions not recommended for your lens type
- Keep lenses away from heat sources, including microwaves and dishwashers
- Do not sleep in your scleral lenses. They are designed for daily wear only
- Apply makeup after lens insertion and remove makeup after lens removal. Choose oil-free, water-based products to reduce deposits
- Do not leave lenses, cases, or solutions in hot cars or direct sun
What to Expect at Replacement Evaluations
Most scleral lens wearers need evaluation every six to twelve months, though we may ask to see you more frequently when you first start wearing lenses or if you have an active eye condition. These visits are essential to catch problems early and determine when replacement is needed. If you accidentally sleep in your lenses or expose them to water, contact us for guidance and schedule a prompt check if advised.
Between scheduled visits, contact us any time you notice changes in comfort, vision, or lens condition. Early evaluation can prevent complications and help us address issues before they become serious.
At your evaluation, we perform several tests to assess both your lenses and your eye health. We examine your lenses under magnification to look for scratches, deposits, warping, and other signs of wear that you might not see at home.
- Microscopic inspection for surface and edge defects
- Assessment of lens clarity and discoloration
- Measurement of lens parameters to detect warping
- Examination of your cornea and conjunctiva for any irritation or damage
- Evaluation of tear film and how well the reservoir behind the lens is maintained
- Anterior segment OCT to measure vault and clearance over the cornea and limbus
- Fluorescein assessment of edge alignment to detect impingement or lift and to evaluate tear exchange
We evaluate how your lenses fit on your eyes using specialized instruments. The fit may change over time as your eye shape changes or as the lenses age and warp slightly.
We also measure your vision with your current lenses to ensure you are still seeing as clearly as possible. If your prescription has changed or the lenses are no longer providing optimal vision correction, we may recommend replacement even if the lenses appear physically sound.
Sometimes we suggest replacing lenses before your scheduled replacement date. This might happen if we find significant deposits, warping, or damage during an exam, or if your eye health requires a different lens design or material.
Early replacement protects your eyes from complications and ensures you continue to receive the vision and comfort benefits that scleral lenses provide. We work with you to plan for these situations and minimize disruption to your daily life.
Planning for Scleral Lens Replacement
When we prescribe your scleral lenses, we provide a recommended replacement timeline based on your individual needs. Treating this as a regular part of your eye care, similar to annual eye exams, helps you budget and plan ahead.
Many patients find it helpful to schedule their lens evaluations and order replacements at the same time each year. We can send reminders when your replacement window approaches so you are never caught without functional lenses.
We strongly recommend having a backup pair of scleral lenses, especially if you depend on them for daily activities like driving or work. Backup lenses ensure you have vision correction if a lens is damaged, lost, or needs unexpected replacement.
- Backup lenses provide peace of mind and safety
- They allow you to continue wearing lenses while a replacement is being made
- Having a spare can be essential if you travel frequently
- Some patients alternate between two pairs to extend overall lifespan
If you damage or lose a lens well before its expected replacement date, contact our office as soon as possible. We can often remake a single lens using your existing parameters, though we may want to evaluate the other lens and your eyes as well. Do not wear a chipped or cracked lens. Use your backup pair while a replacement is made.
Keep your lens prescriptions and fitting details on file so ordering a replacement is faster. Some situations, such as significant eye shape changes, may require a full refitting rather than simply duplicating your previous lens.
Scleral lens replacement costs vary depending on your lens material, complexity, and whether you need new fittings or measurements. We help you understand what your vision insurance covers for routine replacement versus early or urgent replacement.
Some insurance plans cover one set of lenses per year, while others may require medical necessity documentation. We provide the paperwork and coding you need to maximize your benefits and can discuss payment options for costs not covered by insurance.
Frequently Asked Questions
We understand that replacing scleral lenses is an investment, but wearing lenses past their recommended lifespan can put your eye health at risk. Degraded lenses reduce oxygen flow, harbor bacteria, and may cause corneal complications that require treatment and even more expense. We evaluate your specific situation at each visit and only extend replacement timelines when the lenses remain safe and effective.
Coverage varies widely depending on your specific vision or medical insurance plan. Many plans cover scleral lenses as medically necessary devices rather than cosmetic vision correction, which may provide better benefits than standard contact lens coverage. We verify your benefits and help you understand your out-of-pocket costs before ordering replacements.
It is completely normal for one lens to wear out faster than the other, especially if you have different prescriptions or eye conditions in each eye. We can replace just one lens if the other remains in good condition. However, we do examine both lenses at your visit to make sure the second lens is truly still safe to wear.
Try thoroughly cleaning your lenses with fresh solution and allowing them to soak overnight. If your vision is clear immediately after cleaning but becomes blurry again within hours, deposits are the likely cause. If cleaning makes no difference or the cloudiness returns very quickly, the lens material itself has likely degraded and replacement is needed. When in doubt, bring your lenses to our office for evaluation.
Lenses stored properly in fresh solution can remain usable for several months without wear, but they do not last indefinitely. If lenses are stored longer than the solution's recommended disinfection cycle, discard the old solution, clean the lenses, and fully re-disinfect before wearing. The materials can slowly degrade even in storage, and solution can break down or evaporate over time. If you have not worn your lenses in more than a few months, have us evaluate them before inserting them again to ensure they are still safe and properly fitted.
