Who is suitable to wear progressive lenses
Progressive multifocal glasses are suitable for people with presbyopia or visual fatigue, especially teachers, physicians, musicians, computer operators, etc. They not only need to see far and near objects, but also most of the time, need to see objects at intermediate distances such as blackboards, piano scores, and computer screens. A pair of scientifically customized progressive multifocal glasses can simultaneously meet the needs of distance use, near use, and various distances in between. Some special young myopia patients wearing progressive multifocal glasses can also be used to correct the refractive power and effectively relieve eye fatigue.
Choose the right clear sunglasses for your face shape.
A clear eyeglass frame suits the person of different face shapes according to different shapes. For example, a heart-shaped face suits the clearest eyeglass frame, and a square face suits an elliptical transparent eyeglass frame. A round face suits the clear eyeglass frame with an outline. The long face suits the clear eyeglass frame with some width and so on. There are many kinds of clear frames, like oval, round, square frames, and so on.
When choosing clear frames, be careful to choose one that fits the shape of your face. Oval and the round clear frame are more suitable for heart-shaped faces, square faces, and long faces. People with round faces should avoid large frames, dark frames, and wide edges, and don't wear round or square frames.
What are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.
BLUPOND night driving glasses
TAC Semi-polarized Blue light goggles are designed to change your perspective to yellow with computer blue light polarization. Anti-glare high-definition vision blue-blocking glasses protect eyes from blue light and reduce the contrast of bright blue/white glare and flash. The anti-glare night glasses limit distortion. In addition to polarized driving glasses, you can receive a night vision glasses accessory set, with the EVA glasses hard case, screwdriver, sunglasses bag, microfiber cleaning cloth, glasses clip, and night driving glasses gift box.
Drivers can wear night-vision goggles
Night-vision goggles can prevent headlights from blinding, add color saturation, and make the field of vision clearer. The normal night vision glasses are golden yellow in color and have a metal coating on the surface. This is the use of diamond high perspective reflection film technology, in the lens to add color and film layer, in order to maximize the brightness of the object being seen. It is to compensate for the light for driving, which makes light pass through your eye. It can increase the three-dimensional sense of objects, making the line of sight more clear, to avoid confusion caused by blinding headlights.
Glasse for square faces
It's a square face. People with square faces have wider cheeks and a shorter face that looks firm and has a softer facial line. So select a square or a polygon-shaped frame. Usually, square faces visually shorten the face. And they can give a person a kind of relatively strong feeling, like a boy's face. So choose something slightly wider than your face shape, so that they can have the modified effect.
