The white spots
over the cornea
may be allergic in nature or patches of dry cornea caused due wearing of contact lenses.
Management consist of:
1. Artificial tear drops every 4th hourly
2. Antihistamines to provide symptomatic relief
eye drops to take care of inflammation & allergy
4. Wearing of sunglasses/goggles while going out in sun
5. Provide some "contact lens free period" for Oxygen
availability to cornea & prevent dryness.
If symptoms still persist...it will be better to consult an Ophthalmologist
Wishing you good health.
Thanks & take care.
