What is a qualified plano lens?

First, identify the surface. High-quality products should not have obvious scratches, pitting, edge collapse, sand holes, water ripples, bubbles, and other surface defects. Put glasses next to the place of 33 cm or so at the moment. When looking at the object through glasses, there is no phenomenon that the objects become big or decrescent, and you should not have a feeling that the objects are beating. Otherwise, the quality of the glasses has a problem. Next check through the instrument identification. Finally, check whether the trademark, manufacturer, and quality certificate are true and reliable. The lens of the international famous brand product is often engraved with the manufacturer's trademark, which can be found by careful observation on the edge of the lens.



Why are titanium glasses so expensive?

Light Weight. The term 'pure titanium' means a titanium metal material with a purity of more than 99%. A mineral containing titanium was found in 1791, but pure titanium was not produced until 19. Pure titanium glasses are lighter than titanium alloy glasses. For frames of the same design or appearance, titanium frames weigh only half as much as other ordinary metal frames, reducing the load on the bridge of the nose.


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.



How do anti-blue light glasses protect the eyes?

The anti-blue light glasses available on the market, no matter what type, etc., are mainly the difference in anti-blue light effect, light transmittance, and frame, which will affect the cost of glasses. Obviously, the lens is the most important of these. I think that it is basically enough to choose 30% to 40% anti-blue light glasses. It is good to cut off the harmful blue light. It is not necessary to completely eliminate the blue light so that the chromatic aberration will not be too large, the light transmittance is better, and it also has a certain anti-blue light effect.

Of course, to protect the eyes, it is not enough to rely on anti-blue glasses alone. The effect of anti-blue glasses is mainly to reduce the probability of eye diseases, and can not effectively relieve eye fatigue. Normal people between the ages of 20 and 40 blink about 20 times per minute. When you open your eyes and stare at a computer screen that changes rapidly, the number of blinks will be reduced to 4 or 5 times per minute, resulting in serious insufficient secretion of scum and dry eyes. Therefore, no matter how urgent the work is, you must pay attention to the rest of your eyes, close your eyes regularly, use eye drops when needed, and reduce the brightness of the screen as much as possible when looking at the screen. When the brightness of the screen is significantly higher than the ambient light It is easy to cause eye fatigue. Try to use it as little as possible in the dark. To be honest, it is more important to develop a good eye-using habit.


How to Choose Reading Glasses?

Find the right power. When choosing reading glasses, finding the right power would be the most important thing. All reading glasses will have signs or stickers indicating their power. In most cases, they will range from +1 to +4 diopter, in increments of +0.25. So, when choosing reading glasses, try the lowest power first.

Test-drive the glasses. If you have brought reading material with you, try reading it at a comfortable length. If you hold the material too far out to be able to read it, you should increase the power. Keep testing the differences powers until can read clearly at the distance that’s more comfortable for you.



What are polarized lenses for?

Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.
