I bought these glasses reading reviews of other users and I do not regret my choice. Although I think the best way to preserve is total abstinence to the computer. Decision hard to follow when one is fitted. I have a computer 6 years I visit every day a few hours to see more. Since those six years I have noticed that my sight was failing in not being able to decipher a dictionary and no longer able to thread a wire through a needle but my vision again became clear after 3 weeks of vacation without a computer. Recently, in addition to vision problems that are added eye pain 10 minutes spent online. Help! I become intolerant. It's been about three weeks that I bought my glasses. I check the internet every day, I have not hurt the eyes, I can get back to sewing and I can consult a dictionary without the need of my lens. In my case these glasses are really beneficial. I support very well on the nose, no gene leaves a mark against them, but that's trivial. The blank screen is slightly yellow but you get used very quickly. The other colors are not transformed. Aesthetic side, who cares. On the door just to preserve, not to seduce. We're not going to walk in the street with glasses over there much more ugly sight. As against what worries me is the +0.2 correction. Why did you make this correction? What consequences in long terms? Although this is very minimal and that wearing glasses rests sight, we have no explanation. I bought a second pair of glasses for my husband (it may distort mine, it has a big head) and daughter sharing mine.
