I wear eye glasses. I feel that plastic glasses are a little blurry as compared to glass. Is it so?

I wear eye glasses. I feel that plastic glasses are a little blurry as compared to glass. Is it so?

Slight possibility: Although glass lenses offer a subtle advantage in clarity over high index or polycarbonate lenses, typically the advantages of plastic far outweigh glass. Polycarbonate essentially can function as 'safety ' glasses. The drawback however is that plastic tends to scratch more easily no matter what over glasses. Again though, the functionality of plastic is superior. ...Read more

I really need new glasses but cannot afford them. How do I get some? Can I put new lenses in old plastic ones?

If glasses are so near the eyes so much so that eyelashes touch the glass lens often...does it affect the eyesight /vision in anyway??

If glasses are so near the eyes so much so that eyelashes touch the glass lens often...does it affect the eyesight /vision in anyway??

No: No, the position of your glasses doesn't adversely affect your eyes, but will alter the proper focus of the light entering through the lenses. Of course it also depends on how strong the prescription is, with extremely high degrees myopia or hyperopia the vertex difference does make a difference. Also the eyelashes do flick moisture onto the lenses altering clarity. You should make sure lenses fit. ...Read more

Is rubbing alcohol (ethyl or isopropyl) strong enough to damage plastic lens of eyeglasses?

Is rubbing alcohol (ethyl or isopropyl) strong enough to damage plastic lens of eyeglasses?

Generally not: the plastic lenses of eyeglasses from reputable dealers will not be damaged by rubbing alcohol although some frames might be susceptible. Lenses from ordinary retail sources might be made of cheaper plastic and be damaged. However it is always best to clean the lenses with a microfiber cloth and use dish soap if the soil is heavy. ...Read more
