Can Contact Lenses Cause Retinal Detachment?

Contact lenses do not cause retinal detachment. No peer-reviewed evidence has established a direct causal link between wearing standard contact lenses and the retina peeling away from the back of the eye. The concern persists, though, for a reason that makes intuitive sense once you see it: the vast majority of contact lens wearers are myopic, and myopia itself is one of the strongest risk factors for retinal detachment. The lens sitting on your cornea is not the problem. The elongated eyeball that made you need that lens in the first place can be.

Why This Question Keeps Coming Up

If you search online for contact lenses and retinal detachment, you’ll find forums, Q&A sites, and even some eye-care websites that seem to conflate the two. The confusion is understandable. People who experience a retinal detachment often happen to be contact lens wearers, and it’s natural to suspect the thing you put in your eye every day. But this is a classic case of correlation without causation. Contact lenses correct refractive errors, and the most common refractive error is myopia. Myopia, particularly moderate-to-high myopia, changes the physical structure of the eye in ways that raise retinal detachment risk. When someone wearing contacts develops a detachment, the contacts were a bystander.

The same misunderstanding occurs with eyeglasses. Nobody worries that their glasses caused a retinal tear, yet a glasses-wearing myopic person carries the same structural risk as a contact-lens-wearing myopic person. The correction method is irrelevant; the underlying eye anatomy is what matters.

How Myopia Actually Raises Retinal Detachment Risk

In a myopic eye, the eyeball is longer than normal from front to back. That extra length stretches the retina thinner, particularly at the periphery, which makes it more prone to tears and holes. When vitreous fluid seeps through one of those weak spots, it can lift the retina off its supporting tissue, producing what eye doctors call a rhegmatogenous retinal detachment.

The relationship between the degree of myopia and the risk of detachment is not subtle. Research on patients with retinal detachment found that among those younger than 50, more than half had high myopia, defined by an axial length of 26 mm or longer. In patients 50 and older, only about 15 percent had high myopia, suggesting that in younger people, myopia-driven changes to the vitreous are a dominant mechanism, while in older patients, age-related vitreous degeneration takes over as the primary trigger.

This distinction matters if you’re a younger contact lens wearer with a strong prescription. Your risk of retinal detachment is real, but it comes from the shape and internal mechanics of your eye, not from the lens resting on its surface. Switching to glasses or even getting refractive surgery would not eliminate that structural vulnerability.

Orthokeratology Lenses and Retinal Detachment

One type of contact lens does deserve closer scrutiny in this conversation, though the conclusion still isn’t “the lens caused it.” Orthokeratology, or ortho-k, involves wearing rigid gas-permeable lenses overnight to temporarily reshape the cornea so you can see clearly during the day without correction. These lenses are widely used in children and teenagers as a strategy to slow myopia progression. They work on the front surface of the eye and have no direct mechanical effect on the retina at the back.

Still, case reports have documented retinal detachments occurring during ortho-k treatment. One report described two patients who developed bilateral rhegmatogenous retinal detachment while undergoing orthokeratology, both of whom required surgical repair. The authors noted this as the first published instance of bilateral detachment during ortho-k treatment and emphasized that despite the lens’s benefits for myopic correction, patients remain at risk of retinal detachment and need careful monitoring of the peripheral retina, not just the front of the eye.

The important detail here is that the patients were already myopic, which is why they were in ortho-k treatment in the first place. Ortho-k reshapes the cornea; it does not shorten the eyeball. A child with high myopia wearing ortho-k lenses still has the elongated globe and thinned peripheral retina that raise detachment risk. The lenses may be controlling how the myopia progresses, but the existing structural risk doesn’t vanish.

A systematic review and meta-analysis of orthokeratology found that wearers were up to about 3.8 times more likely to experience an adverse event compared with conventional soft contact lens wearers, but the authors cautioned that this evidence base is underdeveloped and more well-designed studies are needed before drawing firm conclusions.

That elevated adverse-event rate encompasses all complications, with the most common being corneal issues like microbial keratitis and corneal staining, not retinal detachment specifically. A separate 10-year follow-up study comparing ortho-k wearers to soft contact lens wearers found no significant difference in the number of adverse events between the two groups, supporting ortho-k’s long-term safety profile in schoolchildren.

⁴

So the picture with ortho-k is nuanced. Retinal detachment has been documented during treatment, but this appears to reflect the underlying myopia risk rather than a lens-induced problem. The takeaway for ortho-k patients is that eye exams should include peripheral retinal checks, not just corneal assessments.

Eye Rubbing as a Mechanical Risk Factor

There is one indirect way that contact lens wear might contribute to conditions affecting the back of the eye, though it’s a stretch to blame the lenses themselves. Contact lens wearers rub their eyes more often than non-wearers. Lenses can cause dryness, itchiness, and the general awareness of something on the eye that invites rubbing. And vigorous, chronic eye rubbing has been linked to a range of serious ocular problems.

A review of the pathogenesis and complications of chronic eye rubbing in allergic eye disease documented that repeated rubbing can cause spikes in intraocular pressure, corneal damage, and even posterior segment disorders including retinal detachment.

⁵

The mechanism makes sense: hard rubbing compresses and deforms the globe, creating transient pressure changes and mechanical stress on the retinal tissue. For someone whose retina is already thin or has small peripheral holes, that added stress could tip the balance.

This is not a reason to panic about adjusting a contact lens with your fingertip. The concern applies to aggressive, habitual rubbing, the kind people with chronic ocular allergies or keratoconus sometimes engage in. But it’s worth knowing: if you find yourself rubbing your eyes hard multiple times a day because your contacts are bothering you, the smarter move is to address the lens fit or switch to a different type rather than keep rubbing. The rubbing is the hazard, not the lens. Fix the itch at its source.

Scleral Lenses and Intraocular Pressure

Scleral lenses are larger rigid lenses that vault over the entire cornea and rest on the white of the eye. They’re used for conditions like keratoconus, severe dry eye, and irregular corneas. Because they sit differently than standard contacts, there has been some concern about whether they could raise the pressure inside the eye, which in theory could affect the optic nerve and, at extreme levels, the retina.

Research has found a modest increase in intraocular pressure with scleral lens wear, generally under 5 mmHg. One study measured central intraocular pressure after two hours of small-diameter scleral lens wear and found no significant difference compared to the control eye or to the same eye before the lens was placed.

⁶

A broader review of the clinical evidence concluded that while a moderate pressure increase of under 5 mmHg does occur in some studies, it is unlikely to affect a healthy optic nerve. However, patients with glaucoma or those already at risk for optic nerve damage could potentially be affected with long-term wear.

⁷

This concern is about the optic nerve and glaucoma, not retinal detachment specifically. Elevated intraocular pressure does not cause the retina to peel off. Retinal detachment involves the retina separating from the tissue beneath it, usually because of a tear or hole, while glaucoma involves damage to the optic nerve from sustained pressure. They’re different conditions with different mechanisms. Scleral lenses are worth mentioning in a conversation about contact lenses and eye health, but they’re not a retinal detachment risk.

What Retinal Detachment Warning Signs Look Like

Whether you wear contacts or not, knowing the symptoms of retinal detachment is genuinely useful, particularly if you’re myopic. The classic warning signs include:

Floaters: a sudden increase in spots, threads, or cobweb-like shapes drifting across your vision, different from the occasional floater most people notice.
Flashes: brief streaks or flickers of light, especially in your peripheral vision, which happen when the vitreous tugs on the retina.
Shadow or curtain: a dark area that seems to creep across your visual field from one side, like a shade being pulled down.
Blurred vision: a sudden, unexplained drop in sharpness that doesn’t improve with blinking or cleaning your lenses.

Retinal detachment is painless, which is part of why people sometimes wait too long before seeking help. A sudden shower of floaters or flashing lights in one eye is an urgent situation. The retina can often be repaired surgically if caught quickly, but the longer it remains detached, the greater the risk of permanent vision loss, especially if the detachment reaches the macula, the central area responsible for sharp, detailed vision.

For contact lens wearers, there’s an extra wrinkle: some of these symptoms overlap with everyday lens annoyances. Blurry vision might get written off as a dirty lens. A visual disturbance might be attributed to a lens shifting out of position. The distinguishing feature is that retinal detachment symptoms don’t resolve when you remove the lens. If you take your contacts out and you’re still seeing flashes or a shadow in your field of vision, that’s not a lens problem.

Who Is Actually at Higher Risk

Since the risk of retinal detachment comes from the eye itself rather than the correction method, it helps to know which factors genuinely raise the odds. Myopia is the most common one, but it’s not the only one.

Family history: having a close relative who experienced retinal detachment increases your risk, suggesting a genetic component to retinal fragility.
Previous detachment: if one eye has had a detachment, the other eye carries an elevated risk.
Prior eye surgery: cataract surgery, in particular, changes the vitreous dynamics inside the eye and raises detachment risk in the months and years that follow.
Eye trauma: a blow to the eye or head can tear the retina, regardless of whether you wear contacts.
Lattice degeneration: thin, patchy areas in the peripheral retina that some people are born with, making tears more likely.
Age: vitreous detachment becomes increasingly common after 50, and the pulling of the vitreous gel away from the retina can create tears in the process.

You’ll notice that “contact lens wear” isn’t on that list. Glasses aren’t on it either. The correction sits on or in front of the eye; it doesn’t alter the retinal anatomy that drives detachment risk. If you’re a high myope wearing contacts, your eye doctor should be checking your peripheral retina periodically regardless of your lens type.

Refractive Surgery and Retinal Detachment

Some contact lens wearers consider refractive surgery like LASIK or PRK as a way to ditch corrective lenses entirely. A common question is whether eliminating the need for contacts or glasses also eliminates the retinal detachment risk associated with myopia. It does not. LASIK reshapes the cornea to change how light is focused, but it does nothing to shorten the eyeball. A person who was highly myopic before LASIK still has an elongated globe, a stretched retina, and the same structural vulnerabilities afterward. The surgery changes the optical correction, not the anatomy that creates the risk.

This is a genuine misconception that some patients carry into their consultations. Post-LASIK patients who no longer need glasses sometimes assume their eyes are “fixed” in a comprehensive sense and stop getting dilated eye exams. That’s a mistake. The retinal risk profile is unchanged, and regular peripheral retinal screenings remain just as important as they were before surgery.

When to Get Your Retina Checked

If you wear contacts and have moderate-to-high myopia, a comprehensive dilated eye exam that includes a look at the peripheral retina is more valuable than the quick refraction check that updates your prescription. Most eye care providers will do this as part of a standard annual exam, but it’s worth confirming, especially if you’re seeing someone primarily for a contact lens fitting. The peripheral retina isn’t always examined during a contact lens appointment unless you ask or your provider makes it routine.

Certain life events should also prompt a retinal check: a sudden change in floaters or flashes, new blurred vision in one eye, any eye trauma, or if you’ve recently had cataract surgery. For ortho-k patients, the case reports discussed earlier reinforce the value of peripheral retinal assessments at follow-up visits, not just corneal topography checks.

For young myopes, whose detachment risk is driven more by axial length than by age-related vitreous changes, starting peripheral retinal checks early and continuing them regularly is the most practical thing you can do.

Catching a retinal tear or area of lattice degeneration before it progresses to a full detachment allows for preventive laser treatment, a quick outpatient procedure that seals the weak area and dramatically reduces the chance of a detachment developing later.
