Highly recommend! My cataract surgery was outstanding. Of all surgeons I interviewed, she was the one who fully educated me to decide. Surgical process was efficient, organized, and results excellent.

Can Rubbing Your Eyes Cause Keratoconus?
Who Is Most at Risk from Eye Rubbing?
While anyone who rubs their eyes heavily over time is creating some risk, certain groups face a significantly higher chance of developing keratoconus as a result. Knowing whether you fall into one of these groups helps you and your eye doctor decide how closely to monitor your corneas.
Atopic conditions, including allergic conjunctivitis, eczema, and asthma, are strongly linked to keratoconus, and eye rubbing is considered the primary reason why. Allergies cause intense itching, itching leads to rubbing, and rubbing damages the cornea over time. The itching can feel so intense that stopping seems impossible without treatment.
If you have seasonal or year-round eye allergies, addressing the itch itself is the most effective way to protect your corneas. Controlling the allergic response reduces the urge to rub before it causes damage.
Young corneas are still developing, which may make them more vulnerable to the mechanical stress caused by rubbing. Children with allergic eye disease who rub frequently should be seen by an eye doctor, particularly if there is any family history of keratoconus. Corneal topography, a mapping test that measures the shape and thickness of the cornea, can detect early changes before symptoms appear.
Parents may not be aware of how often their child is rubbing, especially during screen time, after waking, or throughout allergy season. Starting allergy treatment early can break the itch-rub cycle before any corneal damage takes hold.
Keratoconus has a known genetic component, meaning it can run in families. If a parent or sibling has been diagnosed, your own corneas may be more susceptible to mechanical damage from rubbing. The combination of genetic predisposition and habitual rubbing creates a higher risk than either factor would on its own.
First-degree relatives of keratoconus patients should be especially careful to avoid eye rubbing and to manage any allergy symptoms that trigger the urge. Regular corneal topography screening is a reasonable precaution for this group.
How to Stop Rubbing Your Eyes
Breaking the eye rubbing habit is challenging, especially when allergies are driving it, but there are practical strategies that work. Treating the underlying cause and building new habits gives you the best chance of protecting your corneas over the long term.
Willpower alone is rarely enough when severe itching is the trigger. Antihistamine eye drops and mast cell stabilizer drops reduce the allergic reaction that makes your eyes itch in the first place. Your eye doctor can recommend or prescribe the right option based on your specific symptoms and how severe they are.
In addition to medicated drops, preservative-free artificial tears can help by flushing allergens off the surface of the eye and providing soothing moisture. Applying a cold compress over closed eyes for a few minutes can also reduce itching without placing any pressure on the cornea.
Some people rub their eyes out of habit rather than in response to itching. Common triggers include waking up, feeling tired, or concentrating on a task. The first step toward stopping is simply becoming aware of when and why you are doing it.
Asking a family member or coworker to gently point it out when they notice you rubbing can help build that awareness. Keeping your hands occupied during high-risk moments, or pressing a cool, damp cloth against closed eyes when the urge strikes, gives you a safer alternative that still feels satisfying.
If the itch is too intense to manage on your own, your eye doctor can offer stronger options including prescription-strength allergy drops or a short course of topical corticosteroids. In some cases, a referral to an allergist to treat the root cause of your allergies is the most effective long-term solution.
You should also schedule a corneal topography screening if you have been a habitual eye rubber, particularly if you have noticed blurred or distorted vision, increased sensitivity to light, or frequent changes in your glasses or contact lens prescription. Early detection of corneal changes leads to earlier and more effective treatment.
If You Already Have Keratoconus, Does Stopping Help?
If keratoconus has already developed, stopping eye rubbing will not reverse the changes that have already occurred. However, eliminating this source of ongoing mechanical stress is still one of the most important steps you can take to slow or stop further progression of the condition.
The thinning and shape distortion that keratoconus causes are permanent without surgical intervention. What stopping rubbing can do is remove one of the ongoing forces that continues to push the condition forward. Patients who eliminate rubbing take away a meaningful driver of worsening and give their corneas a better chance of remaining stable.
Corneal cross-linking (CXL) is a procedure that uses ultraviolet light and riboflavin eye drops to strengthen the collagen bonds in the cornea, helping it resist further thinning and shape change. Stopping eye rubbing addresses the same problem from the outside, by removing the mechanical stress that weakens those bonds. Together, these two approaches work in a complementary way to slow or halt keratoconus progression.
Our eye doctors may recommend confirming that you have stopped rubbing and that your allergy symptoms are well controlled before scheduling cross-linking. Continuing to rub after the procedure can reduce how well the treatment holds over time.
After you stop rubbing, your eye doctor will continue to monitor your corneas using serial topography, meaning repeat mapping tests taken over time to look for any change in shape or thickness. Stable results across several visits are a good sign that removing the rubbing habit is making a difference.
Depending on your individual situation, monitoring visits may be scheduled every three to six months during the first year. If your cornea remains stable, the interval between visits may be extended. If progression continues despite stopping, your eye doctor will discuss the appropriate next steps, which may include corneal cross-linking or other corneal treatments available at our practice.
Frequently Asked Questions
These answers address common questions our patients ask about eye rubbing and keratoconus, including guidance on what to do and when to act.
Brief, light rubbing in a healthy person without additional risk factors is unlikely to cause keratoconus on its own. The concern is with habitual, vigorous rubbing that happens repeatedly over months or years. If you have allergies, a family history of keratoconus, or already have mild corneal irregularity, even moderate rubbing raises your risk meaningfully, so it is worth addressing even if you do not rub aggressively.
Yes, especially if your child has allergies or a family member with keratoconus. Frequent rubbing in children warrants a visit to an eye doctor for a corneal topography screening, which can catch early corneal changes before they affect vision. The most practical step you can take right away is to have your child evaluated for allergic eye disease, since treating the itch is the most effective way to reduce the rubbing.
No. Your eye doctor will give specific instructions to avoid rubbing both during the healing period immediately after cross-linking and as an ongoing practice. Rubbing after CXL can compromise the structural changes the procedure was designed to create, reducing its long-term benefit. If itching is a problem after the procedure, preservative-free drops or antihistamine drops are the safe way to find relief without putting pressure on the cornea.
Yes, it can. A cornea affected by keratoconus is already structurally weaker than a healthy one, which makes it more vulnerable to the mechanical stress that rubbing creates. Continuing to rub when you have keratoconus removes the stability the cornea needs to remain in its current state. Stopping rubbing is one of the most direct actions you can take to slow disease progression, and it works best when combined with appropriate medical management.
Cold compresses applied gently over closed eyelids are one of the most effective options, they reduce inflammation and itching without applying shear force to the cornea. Preservative-free artificial tears provide comfort and flush away irritants. If allergies are the cause, antihistamine eye drops address the itch at its source. For persistent or severe symptoms, your eye doctor can recommend prescription-strength drops that provide relief without the risks of rubbing.
Corneal topography is the standard test used to detect early changes in corneal shape and thickness. It is painless, takes only a few minutes, and can reveal subtle irregularities well before you notice any changes in your vision. If you have been a habitual eye rubber for years, asking your eye doctor to include topography as part of your exam is a reasonable and proactive step, particularly if you also have allergies or a family history of keratoconus.
