What to do now
Remove the contact lens if it comes out easily, stop wearing lenses and arrange urgent same-day assessment by an eye-care professional. If pain, blurred vision, light sensitivity or redness is severe or getting worse, use a local emergency eye service.
Bring the lens case, solution and lens details if convenient, but do not delay care to collect them. Tell the clinician how long the lens was worn and whether you slept, showered or swam in it.
What to avoid
Do not put the lens back in, rinse it with tap water, share lenses or use leftover antibiotic or steroid drops. Do not patch the eye or wait several days to see if a painful red eye settles.
Contact lenses can increase the risk of certain corneal infections. Only an examination can determine the cause and the right treatment.
How to reduce future lens-related risk
Follow the wearing schedule and cleaning instructions provided for your specific lenses. Keep lenses and cases away from water, replace the case as directed, and do not sleep in lenses unless an eye-care professional has specifically prescribed that use.
Stop lens wear and seek advice whenever an eye becomes painful, red, unusually light-sensitive or blurrier. The consultation location listed for Dr. Rajat Jain is in Shalimar Bagh, Delhi; call ahead, but do not delay urgent local care to travel there.
