Glasses are tools to protect your eyes.
Wearing glasses can relieve eye strain. Myopia without glasses will inevitably lead to eyes easy fatigue, so the result can only be a deepening of the degree. After wearing glasses normally, the phenomenon of visual fatigue will be greatly reduced. For young people, because the eyeball is still in the development period, regulatory myopia easily develops into axial myopia. Especially for high myopia, the diameter of the eyeball before and after is significantly prolonged. If the myopia is rectified by wearing a normal lens from the beginning, this situation will be reduced or even not occur. If people with Myopic did not wear lenses in time, it will cause ametropic amblyopia. So if wear appropriate glasses, after a longer treatment, most eyesight will be gradually improved.
What Do Pinhole Glasses Do?
Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.
Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.
The fabric of eyeglasses cloth
Ordinary fabric: They are only applicable to the surface that has been cleaned.Because the ordinary fabric has no space to accommodate dirt, the surface of the cloth will be very dirty, and difficult to wash clean.
Microfiber fabrics: They are used wet to emulsify dirt and oil, and the microfiber is easier to wipe off. It is highly absorbent, making it very quick to clean the spilled liquid.
Fine fiber double velvet fabric: It feels soft, gentle, with the plump texture, but more single velvet.
Suede fabric: The feel and appearance are quite like natural suede, fine and smooth, soft and plump, used to wipe glasses. It will be clean and won't scratch the lens.
How to clean the lenses?
When wiping lenses (especially the rimless glasses of resin lens), you must use a special wipe lens or soft handkerchief or paper. When you wipe the lens, you can only wipe it in one direction, not in circles, and don't touch the lens with your fingers. When the lens is stained with dust and sand, it should be washed with water before wiping, otherwise, the lens is likely to be abraded, and the operation should be gentle. At ordinary times, when cleaning, do not exert too much force, pay attention to the grasp of strength. When wiping the lens, it is best to take the side frame with one hand, and the other hand takes the glasses cloth to wipe gently. In order to prevent the lens film layer falls off, do not use alkaline detergent to wipe the lens. Therefore, when bathing or playing at the seaside, glasses should be properly kept to avoid water vapor or seawater caused by corrosion of glasses.

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.
