I found my left eye vision slightly blurry in the past one week, and decided to pay my optometrician a visit this afternoon. I suspected it was due to my astigmatism, it could probably has increased to +125 for my left eye.
Guess what? I was wrong.
After checking my eyesight and had read "D, E, F, G, T" more than thrice, she advised me to add +25 to my left eye.
I asked: What does it mean by +25?
She answered: Long-sightedness.
