My eyesight number is increased from the previous one. I was using these glasses from 3-4 years and before this as well my number got increased little bit, i don't remember the earlier one numbers but my current eyesight number is as follows : Right Eye : sph -1.00, cyl-1.25, axis 100 Left eye: sph-1.25, cyl-1.75, axix 80 My question is that , 1. As my eye sight number is increasing after every 3-4 years , should i need to worry about this ? How i can prevent this however i wear glasses all the time. 2. Should i go for the Lasik surgery with my current eyesight numbers and will this not increase after Lasik as i want to get rid of glasses? Please help me to understand this. Many thanks in Advance!
