Daily wear means in every morning, out every night
Scleral lenses are made to be worn during the day and removed before sleep. Once you’ve built up to your fitter’s schedule, most people wear them on most days. In a one-year study of 95 wearers, people new to scleral lenses averaged 11.1 hours a day and 5.6 days a week by the twelve-month mark.[1] Some people want their lenses every waking day; others mix in glasses days. Both are fine.
How many hours you wear them each day is a separate question, covered in how many hours a day you can wear scleral lenses.
What research says about wearing them day after day
Short-term effects on the cornea are small. A 2026 meta-analysis pooled 22 studies covering 830 eyes. While the lens was in, the cornea thickened very slightly on average, and that difference was no longer significant after the lens came out. Pressure inside the eye didn’t change significantly. The authors concluded that daytime wear of modern high-oxygen lenses appears to be physiologically safe, while still advising monitoring for higher-risk patients.[2]
People wear them for years. A 21-year review at one specialty center followed 209 children’s eyes fitted with scleral lenses. Of these, 70% were still wearing them at the time of the review, with an average of 8.2 years of wear.[3]
Problems still happen. In a retrospective study of 157 eyes with keratoconus that had worn scleral lenses for at least a year, 9.6% of eyes had a physiological problem at some point, including infection in 0.6% and corneal abrasion in 1.3%. Lens problems were more common: 26.1% of eyes had a broken lens and 7.0% had fogging.[4] A survey of fitters covering 72,605 wearers estimated that over one year, 1.2% stopped wearing because of corneal swelling and 0.45% because of infection.[5]
Those numbers are low, but they aren’t zero, and some of these problems can develop quietly. Long-term daily wear works best with long-term follow-up.
What keeps daily wear safe
- Clean and disinfect every night. Rub, rinse, and store each lens in fresh disinfecting solution. Never top off old solution.[7] Our cleaning guide has the steps.
- Never sleep in them. Not even a nap. See can you sleep in scleral lenses.
- Keep water away. No tap water on the lens or in the case, and lenses out for swimming.[7]
- Replace your case regularly. The FDA advises every three months or as your eye care professional directs.[7]
- Keep backup glasses with a current prescription.[6] You’ll need them on any day a lens breaks, gets lost, or your eye needs a rest.
- Keep your follow-up visits, even when everything feels fine.[6]
When to take a day off
Your fitter may ask you to stop wearing a lens for a while if they see a problem, or after eye surgery or an infection. On your own, take the day off and wear glasses if your eye is red, irritated, or your vision isn’t right, and call if it doesn’t settle. Don’t wear a lens that’s chipped or cracked.

Common questions
Do I need to take days off from my scleral lenses?
Not as a rule, unless your fitter asks you to. Some wearers choose glasses on some days, and that's fine too. In a one-year study, new wearers averaged five to six days a week by the end of the year.
Will wearing them every day damage my eyes over time?
Pooled research on daytime wear shows small, mostly reversible changes on average, but problems such as corneal swelling or infection can happen and some don't cause symptoms early. That's why ongoing follow-up visits matter even when everything feels fine.
Can I wear them every day if I have a corneal transplant?
Many people with transplants do wear scleral lenses, but your fitter and corneal surgeon may watch your cornea more closely. Ask them what schedule and follow-up they recommend for you.
