I want to know about presbyopia symptoms.

I'm in my 40s.

Since when, one day, one of my eyes started to look blurry.

It looks clear.

I thought it was because I use the computer and phone a lot, but after resting, I feel better again.

It seems to happen every few days.

Recently, I had a stye in my eye and went to the ophthalmologist, who said my vision was 1.0 and there was no problem.

Suddenly, I'm worried about presbyopia.
