    Question

    Can I wear scleral lenses if I have eye allergies?

    Itchy, watery allergy seasons and contact lenses don't always mix. Here's how allergies affect scleral lens wear, what giant papillary conjunctivitis is, and what you and your fitter can do.

    The short answer

    Usually, yes. Most eye allergies are a nuisance rather than a reason to stop, but they can make lenses less comfortable and coat them with deposits. The main lens-related allergy to know about is giant papillary conjunctivitis (GPC), a reaction under the upper eyelid that can happen with any contact lens, including scleral lenses. It usually settles with a break from the lens, better cleaning, and sometimes a new lens or medicated drops. Don't put allergy drops into the lens bowl unless your doctor tells you to.

    Key points

    • Seasonal and year-round allergic conjunctivitis are common and rarely threaten sight.
    • GPC causes itching, mucus, blurry vision and lens intolerance, and has a good outlook with treatment.
    • Deposits on the lens surface are thought to help trigger GPC, so daily cleaning matters.
    • Ask your doctor how to time allergy drops around your lenses.

    Allergies and contact lenses

    Allergic conjunctivitis is common, and it’s becoming more so. It ranges from seasonal hay fever eyes to year-round allergies to dust mites or pets. It’s rarely sight-threatening, though it can seriously affect comfort, sleep and work.[1]

    Two more severe forms, vernal and atopic keratoconjunctivitis, are chronic inflammatory conditions that can involve the cornea and lead to complications. They need an eye doctor’s care.[1] Giant papillary conjunctivitis (GPC) is also classed with the eye allergies. It’s linked to contact lens wear and to the small, repeated rubbing of an ocular prosthesis.[1]

    Giant papillary conjunctivitis

    GPC is a common complication of contact lens wear. Bumps (papillae) form on the inside of the upper eyelid, and people notice extra mucus, itching, blurry vision, and less tolerance of their lenses.[2]

    Why it happens. It’s thought to come from a combination of mechanical rubbing of the upper eyelid lining and an immune reaction to deposits on the front of the lens.[2] With scleral lenses, the blinking eyelid moves over the lens, and debris and proteins that build up on the lens surface can act as triggers.[3]

    Who is at higher risk. Risk factors include lenses that are replaced infrequently, long wearing times, inadequate lens hygiene, and having allergies in general (atopy).[2]

    How common it is with scleral lenses. GPC can happen with any contact lens, but it’s particularly common with soft lenses.[3] We didn’t find a reliable rate for scleral lens wearers. Deposits, one suspected trigger, are a common scleral lens problem: in a keratoconus study they were recorded in 8.9% of eyes.[4]

    How it’s managed. The outlook is excellent with proper management. In mild cases, a break from lens wear may be enough. More severe cases may need anti-allergy drops, and less often other medicines.[2] For scleral lens wearers, the options include a break from wear, better lens hygiene, a different lens material, and a new lens.[3] Which of these you need is your eye doctor’s decision.

    Allergy drops and scleral lenses

    The bowl of a scleral lens holds fluid against your cornea for hours, so what goes in it matters. Fill it only with the sterile, preservative-free solution your fitter prescribes. Benzalkonium chloride, a preservative used in about 70% of eye drop formulations, can damage the eye’s surface cells.[5] Preservatives in medicines are one of the known causes of toxic surface damage under scleral lenses.[3]

    Ask your eye doctor:

    • Whether to use your allergy drops before inserting the lens or after removing it
    • Whether there’s a preservative-free version
    • Whether any allergy medicine you take by mouth could be affecting your eyes. One review lists antihistamines among the many possible contributors to reduced corneal nerve function.[6]

    Day-to-day steps that help

    Common questions

    Can I use my allergy eye drops while wearing scleral lenses?

    Ask your eye doctor before you do. Many eye drops contain preservatives, which shouldn't be trapped in the fluid behind a scleral lens for hours. Your doctor can tell you whether to use the drops before you insert the lens or after you remove it, and whether a preservative-free option is available. Never add drops to the lens bowl unless you're specifically told to.

    My lens feels fine in the morning but my eye gets itchy and stringy by afternoon. Is that GPC?

    It might be, but other things can cause similar symptoms, including dry eye, a lens that needs cleaning or replacing, or a fit problem. Itching, mucus and lens discomfort are typical of GPC. Your fitter can check by flipping your upper eyelid and looking at its inner surface.

    Do scleral lenses protect my eyes from pollen?

    We couldn't find research testing this. A scleral lens covers the cornea, but the conjunctiva around it and under the eyelids, which is where allergic reactions mostly happen, is still exposed. Don't count on the lens as allergy protection.

    Will taking an allergy pill dry my eyes and affect my lenses?

    Ask your doctor or pharmacist. One review lists antihistamines among the many possible contributors to reduced corneal nerve function, but whether that matters for you depends on the medicine, the dose, and your eyes.

    Can you use eye drops with scleral lenses?

    Usually, yes, with the right drops in the right place. Preservative-free artificial tears your fitter approves can generally go on top of the lens during the day. Only sterile, preservative-free saline goes in the bowl of the lens, unless your doctor prescribes something else to go there. Prescription drops, including glaucoma drops, are usually timed around lens wear, so ask your fitter and the doctor who prescribed them how to fit them into your day.

    Can I wear scleral lenses with blepharitis or MGD?

    Yes, most people can, but treating the eyelids is part of making the lenses work. Blepharitis and meibomian gland dysfunction (MGD) disturb the tear film over the front of the lens, which can make vision hazy a few hours into the day. Research links this front-surface fogging to poor wetting of the lens surface and to eye surface inflammation. Lid treatment, a lens surface treatment, and sometimes a planned midday clean and refill can all help.

    Can I wear scleral lenses if I have ocular rosacea?

    Often, yes, but treating the rosacea comes first and continues alongside the lens. Ocular rosacea inflames the eyelid margins and oil glands and can, in more severe cases, damage the cornea. Eyelid disease of this kind is common among scleral lens wearers and is linked to blurry, fogged vision through the lens. A scleral lens may help if rosacea has left your cornea scarred or your eye very dry, but we found no studies of scleral lenses in ocular rosacea specifically.

    Can scleral lenses help with light sensitivity?

    Sometimes. If your light sensitivity comes from a damaged, dry, or irregular front surface of the eye, a scleral lens may reduce it by covering and bathing the cornea and by smoothing the glare and halos an irregular cornea causes. A standard scleral lens is clear, though, so it doesn't block light, and it won't help light sensitivity that comes from inside the eye, the nerves, or migraine. New light sensitivity while you're wearing scleral lenses can be a sign of a problem: remove the lens and call your eye doctor.

    Can I wear scleral lenses if I have glaucoma?

    Often, yes, but it takes planning between your fitter and the doctor who manages your glaucoma. On average, studies find little or no change in eye pressure after scleral lens wear, but almost none were done in people who already have glaucoma, and pressure while the lens is on the eye is hard to measure. Preserved glaucoma drops shouldn't be trapped under the lens, and a filtering bleb or drainage tube usually means a specially shaped lens.
