Because of the overuse of our eyes for studying and working through computer screens, nowadays people who have eyesight problems are becoming more and more. We cannot help that. Maybe that is the disadvantage bring about by modern technology that we cannot avoid. As a result, the increasing need for prescription eyeglasses has stimulated the quick development of optical industry. Prescription eyeglasses have become daily necessities for many people, and they are not only used for eyesight-correcting, but also for cosmetic ornaments.
When asking an eyeglasses wearer how many pairs of prescription eyeglasses they own, I am sure most of them would say that they have at least two pairs, especially to the youth. Yes, we need different styles of eyeglasses to suit different situations, seasons and dressings.
Since most people need to buy eyeglasses regularly, we must be fully awarded what in reality a good pair of prescription eyeglasses is. In my opinion, a good pair of prescription glasses & sunglasses should have the following qualities: First, the lenses should be good enough. Though there are many kinds of lenses in the market, and different materials have different advantages, we must choose the one that suit us best. In general, plastic lenses are durable and impact-resist, and light in weight; while lenses made of glass are usually heavier than plastic ones, and easily breakable, but they have different eyesight corrective strengths. Glass lenses have better radiation-preventing ability than plastic ones, so if you have to face the computer screen all the time, glass lenses are better choices. Second, the frame is also of vital importance. It is far from enough if a pair of eyeglasses only has good lenses but inferior frame. You know, the eyeglasses have to be put on our nose for most of the time of a day, it mustn’t give too much pressure to the nose, otherwise, we would feel uncomfortable. The good frame should be lightweight and suit our face type well, neither too narrow nor too wide. Besides, the shape, color and material of the frame should also be taken into account since it is the very part of the eyeglasses that determine the wearers’ appearance.
We can see many optical stores in the street, but I think online stores are the best places to buy good yet cheap eyeglasses because it is money and time saving. www.cheapprescriptionglasses.net is a net store that I trust. I am sure you will also enjoy your purchase there. |
