iTear100 Neuro-Stimulation for Dry Eye Relief
What is iTear100?
iTear100 is a small, handheld, prescription device designed to treat dry eye symptoms by activating the body's natural tear production. It works without medications or invasive procedures, making it a convenient and effective choice for daily use.
About the size of a marker, the iTear100 is a tool that fits comfortably in your hand. You apply its soft tip to the skin on the side of the nose to activate nerves that signal your eyes to produce tears. This process is quick and can be done at home, helping to naturally restore moisture to your eyes.
Unlike traditional eye drops that add artificial moisture, iTear100 helps your body make its own tears, which can lead to longer-lasting relief. Studies show that this neuro-stimulation can increase tear production within minutes, offering a drug-free alternative for those who find eye drops irritating or forget to use them regularly.
The iTear100 was created by experts in eye care technology to address chronic dry eye issues. It is based on years of research into how nerves control the tear glands and applies the proven science of neuro-stimulation, which has been used successfully in other medical fields.
The iTear100 device received clearance from the U.S. FDA in 2020 after a rigorous evaluation of its safety and effectiveness. Multiple clinical studies demonstrated that it can significantly improve tear production and reduce dry eye symptoms, providing confidence that the device is both safe and effective when used as directed.
Because iTear100 is a prescription device, you must get it through an eye care professional. Your doctor will evaluate your dry eye condition to determine if this treatment is right for you and will provide training on how to use it correctly to maximize its benefits.
How Does iTear100 Work?
The device uses safe, low-level electrical pulses to stimulate a specific nerve, prompting your eyes to produce tears naturally. This non-invasive method provides quick relief and is simple to use after a short demonstration from your eye care provider.
Neuro-stimulation involves sending small electrical pulses to the external nasal nerve. This nerve sends a signal to your brain to activate the tear glands, helping to lubricate your eyes. Research shows that many patients experience a significant increase in tear volume within a few minutes.
Using the iTear100 is straightforward. First, ensure the device is fully charged. Then, place the tip on the skin on the side of your nose for about 30 seconds. You can then repeat the process on the other side. Most users find relief with one to three sessions per day as needed.
Most people feel a gentle buzzing or tingling sensation at the application site, which is normal and not painful. Your eyes may begin to water immediately, bringing relief from dryness. Over time, regular use can improve your overall eye comfort and moisture levels.
The tear production stimulated by iTear100 can last from several minutes to a few hours, depending on the individual, environmental conditions, and the severity of the dry eye. Regular daily use may help maintain better baseline moisture levels in the eyes.
Benefits of iTear100
Using iTear100 can help reduce the frustrating symptoms of dry eye and improve daily life without the constant need for drops. It's a modern, convenient approach that fits easily into busy schedules and supports your eye health.
Dry eye symptoms like burning, itching, or blurry vision can be eased within seconds of using iTear100. This fast action makes it helpful for moments when you need immediate comfort, such as during breaks from work or driving.
Since it does not involve medications, iTear100 avoids the potential for irritation or allergic reactions from preservatives found in many eye drops. It is an ideal alternative for patients who prefer non-pharmacologic treatments.
The device is compact enough to carry in a bag or pocket, so you can use it anywhere. It recharges like a phone, which means you do not have to plan your day around eye drop schedules, giving you more freedom and flexibility.
Regular stimulation may help keep your tear glands active and healthy. This can reduce the risk of complications from chronic dry eye, such as eye infections. Combining its use with good habits, like blinking often and staying hydrated, can enhance its benefits.
Many patients experience a significant reduction in their use of artificial tears after starting consistent iTear100 treatments. This can improve quality of life and reduce the ongoing expense of purchasing eye drops.
Who Can Benefit from iTear100?
This device is suitable for many adults with dry eye, especially those who have not found adequate relief from other methods. However, it is important to consult with an eye care professional to ensure it is the right choice for your specific needs.
People with mild to moderate dry eye caused by aging, screen use, or environmental factors often see good results. It can also be beneficial for contact lens wearers and patients who have had eye surgery and are managing ongoing dryness.
iTear100 works best for dry eye linked to low tear production (aqueous deficient dry eye). It can help with dryness related to menopause, medication side effects, or autoimmune conditions like Sjögren’s syndrome.
If you have severe dry eye that requires more advanced therapies, or if you have certain nerve disorders, this device may not be the best choice. A proper evaluation from your eye doctor is essential to ensure safety and effectiveness for your condition.
Potential Side Effects and Safety
While iTear100 is generally well-tolerated and safe, it is good to be aware of possible mild effects and how to use it properly. Most users experience no significant issues, but following safety guidelines ensures a comfortable experience.
Some people may notice a slight tingling, warmth, or redness on the skin where the tip is applied. These effects are temporary, usually fade quickly, and do not affect your eyes directly.
Always follow the device's instructions and keep the tip clean by wiping it with a dry cloth or alcohol pad after each use. Avoid using it on broken or irritated skin, or if you have known allergies to the device materials.
In clinical trials, over 90% of users reported no significant side effects, highlighting its strong safety record. This data helps confirm that it is a trusted and reliable option for many patients seeking dry eye relief.

Yes. Since the device is only applied to the skin on the side of your nose, it does not interfere with contact lenses. Many contact lens wearers find it helpful for managing dryness and improving lens comfort throughout the day.
Patients with pacemakers, implanted defibrillators, or other neurostimulators should not use iTear100 unless cleared by their cardiologist or specialist. The electrical stimulation could potentially interfere with these types of implanted devices.
If you have not noticed relief after two to four weeks of consistent use, schedule a follow-up with your eye care professional. They can review your usage, adjust your treatment plan, or explore other potential causes for your dry eye symptoms.
