As a fashionable person with nearsighted eyes, it can be a bit of a hassle to keep up with the trends. The frames of sunglasses are relatively large, and as long as the idea is based on fashion aesthetics, the design does not take into account some of the actual parameters of the glasses. For example, the width and length of the frame, the width of the nose bridge, and the overall curvature of the frame, etc. These are all parameters that must be considered for optical frames.
Nearsighted glasses, you also need to choose the frame according to the optometry prescription list, the actual myopia. Can you choose sunglasses to make frame descriptions from the following aspects.
1, high myopia can not choose frameless, large frame (similar to the frame of sunglasses). Because highly myopic people, the lens is too thick (myopic lenses are thin in the middle and thick at the edges), the frame is large, the thicker the edges the better to make out. One is the impact of aesthetics, one is the weight, long time to wear pressure on the bridge of the nose, the comfort is very poor.
2, sunglasses frame is large, will make the optical center of the lens shift, so that the pupil distance, near eye distance has a large deviation, will produce unclear vision, dizziness and other phenomena.
3, the overall frame of sunglasses also has a curved arc too large, will change the actual luminosity of the lens, easy to cause visual fatigue, deepening eye myopia. Especially myopic patients with small pupil distance should not choose the frame of sunglasses to do the optical frame.
In general, sunglasses are also available with lenses, provided that they are flat, without degrees, and the optical center of the lens has an impact, so that they can be customized. If in order to correct vision, should consider the refraction, astigmatism axis, pupil distance, frame style (half frame, full frame, frameless) and many other factors, and then in consideration of its beauty and fashion, and face shape with the matching frame.
