I have been using glasses when I was 10. Now I'm 31+ . For the last 4/5 yrs there was not much change in my eye power. But today I have checked my eyes and my left sided vision is reduced. From 2005 to 10 my glasses were -6.5 on rt eye nd -5.5on left, in 10 hv got -7 on rt nd - 6.25 on left .today it was -7.25 on rt -7.5 on left. I'm very very worried now , what to do? I hv heard that we should not use fully corrected glass as eye become adapted wuth over correction.I'm studying medicine at this moment and I hv a imp exam in front. Don't want do LASIK now as its very costly for me. About contact lenses I'm confused as one optometrist said because of dryness I can't use those and another said its not a big problem. Plz help me with good advice.
