When I was young, my eye vision became poorer and poorer because of the heavy-duty from the study. Thus, I had to buy a pair of glasses to correct my vision. But in fact, I'd rather refuse to wear the glasses at that time as it was heavy, ugly, and most of all, made me feel uncomfortable. So I didn't wear it all the time and that's why now I have a stronger prescription.
, the eyeglasses, both the lenses and the frames have experienced huge technical innovation for the past ten years. The basic lens – single vision lenses have been greatly superseded by multifocal lenses. Traditional plastic and glass lenses have been largely replaced by lenses made of superior materials like high-index plastics and polycarbonate lenses. If you have a strong eyeglasses prescription like mine, you can choose high index lenses such as 1.61, and 1.67, which are much thinner than the normal CR39 lenses and lighter than glass lenses. Today, prescription lenses with their unique functions have been developed to solve different vision problems. Nevertheless, some lenses combine two or more functions into one lens, such as polarized bifocal lenses or photochromic progressive lenses. But there is not much difference in appearance.
However, eyeglass frames have changed a lot in appearance year by year. Some adopted simple designs aiming for the lightest weight possible. Some are made of flexible materials which are super durable. Others may have fashionable and artistic designs on temples which are very welcomed by young people and faddish ones. On the other hand, eyeglass frames can be classified into three main types: Full rim frame, Semi-rimless frame, and Rimless (frameless) frame. Full-rim type is the most durable one among the three and recommended for people with strong prescriptions; semi-rim frames have less weight and are good for people with allergy problems because when you wear such frames, your cheek will have no contact with the metal rim; rimless frames are the lightest type which has been designed for people with extraordinary fashion needs.
Thus, we wear eyeglasses not only to correct our vision problems but also to follow the latest fashion trends. That is why nowadays a lot of people still wear eyeglasses even if they have good eyesight, to match their daily dress up.
I have ordered several pairs of eyeglasses from www.cheapglasses123.com, and they are great! There are thousands of styles that you can choose from, definitely worth visiting, no matter for prescription eyeglasses or fashion-only glasses.
