(Concern) Decreased vision

I had LASIK surgery in 2011.

My vision after the surgery was not very good either.

Since then, my eyesight has significantly deteriorated over time.

The most recent visual acuity measurement is 0.5 and 0.3.

But it's more uncomfortable that my eyesight has deteriorated.

The difference in eyesight between the dry winter and the humid summer is too extreme..

0.5 and 0.3 are the visual acuities measured in winter.

Four months ago in the summer, when I weighed myself, it was 1.2 and 0.9.

It was usually around 0.7 to 0.4 before.

Does it really get affected so much by the weather?
