While eyeglasses solve most vision problems, they do have some problems associated with them. The first issue is reflective glare. Reflective glare makes it difficult for people to see your eyes through the glass, it leaves white spots on photographs, and it makes it difficult for the wearer to see out at times. In order to reduce this problem there is an anti-reflective coating that can be applied to your lenses that will reduce these problems and make seeing out of your glasses easier.
Scratching is another issue that eyeglass wearers have to deal with. There are scratch-resistant coatings that can be applied to both glass and plastic lenses. If scratching is a big concern of yours, and if you don’t have a very strong prescription, then you should consider selecting glass lenses over plastic lenses, as glass is less likely to scratch.
Breaking or damage to the frame are also concerns that eyeglass wearers worry about, especially when the wearer is a child or adolescent. In order to reduce the chances that the frame will be bent, broken, or over-flexed you can purchase a flexible frame, or buy a pair of wire glasses that have hinges that over-extend. This option is also practical for people who have wider than average heads, who have found it difficult in the past to find a pair of glasses that comfortably fit their head shape.
Thick lenses are another concern that eyeglass wearers struggle with. Thick lenses are often the only option available to people with severe vision problems. In the past when lenses were only made out of glass, these prescriptions were heavy, uncomfortable, and embarrassing to wear especially when the person was a child or adolescent. Plastic lenses have reduced the weight of heavy prescriptions, however, they still seem thick and unfashionable. Now people with a strong prescription can opt to buy high-index lenses that are compressed thereby reducing the bulk of the lense, or they can buy aspheric lenses, which utilize a flatter curvature than most other lense types.
