I had my regular eye checkup in last week of March 2021 where my eyes were myopic (right eye: -3.50 and left eye:-1.50). Recently a week back I had irritation & pain in inner corner of my right eyelid and I was experiencing blurred vision with my prescription glasses on. I visited opthalmologist and he said myopia in my right eye has progressed to -4.25 from -3.50 (in just two months) while the power in left eye remained same. When I told doctor about the pain in the inner corner of eye lid he prescribed an antibiotic eye drop and said it is very difficult to comment about the reason of such rapid myopic progression. He didn't recommended any test/referral.Now I still have a slight pain in the inner corner of my eye though I can see well with the new prescription glasses. Can you please tell the reason of such rapid myopic progression? P.S. I had history of severe Vit D deficiency and covid 1.5 months back. I consulted with ENT yesterday. He said I have allergy everything else is fine.
