Do glasses worsen eyesight?

Is it expensive to fix glasses?

Many optician shops can fix a broken pair of frames for less than $50. Some retailers, like LensCrafters, provide glasses with a one-year extended warranty for as low as $35. If you have such a warranty, you can have your glasses repaired for a fraction of the cost. Is it expensive to fix glasses? It depends on the specific situation. World Optic, for example, has led the eyeglass repair industry since 1972. World Optic combines over 90 years of eyeglass repair experience and uses cutting-edge technology to create a complete science of the process of repairing broken glasses and sunglasses from start to finish. We have to see that for every single repair, there is a specific quote for different degrees of repair and for different parts.


Refractive index of spectacle lens

It is generally believed that the higher the refractive index, the better the spectacle lens. Such spectacle lenses are relatively thin, and of course, the price is a bit expensive. When the refractive index increases, the direction of the light entering the lens will change greatly, the focus will move to the lens, the focal length will be smaller, and the diopter will become larger. In order to keep the diopter unchanged, it is necessary to reduce the curvature of the lens, that is, to reduce the curvature of the mirror surface, so that the thickness of the lens can be reduced. This is why the larger the refractive index, the thinner the lens is. Under the same premise of other things, the larger the refractive index, the thinner the lens, the lighter and more beautiful the lens, and the higher the price, but the larger the refractive index is not the better.



What Should You Do If Your Glasses Are Broken?

Adjust the frame by yourself. If your frame is tilted, place your glasses on a flat surface to determine which arm is higher than the other. If the right arm looks raised, you'll need to use pliers to bend the left arm down at the hinge. Or, if the left arm is raised, bend the right arm at the hinge. You can bend your metal-framed arms inward. You can turn the nose pad inward if the glasses slip under your nose. To make the frames more flexible, you can heat them with a hairdryer. If the metal frame has broken into pieces, you may need to take it to a professional. However, if your metal frames just bend, you may be able to repair them by yourself.

Anti-reflection Coating

Anti-reflection Coating, known as reflective coating and antireflection film, is called anti-reflection coating in English, or AR Coating for short. Initially, anti-reflection coating technology was used in the sights of weapons. It was only after the war that the technique was used to improve the performance of eyeglasses. Another problem occurs when taking pictures because the lens's surface is relatively reflective. The resulting photos don't show the eyes of friends who wear glasses. This problem is solved by plating anti-reflection film.
