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 blue light glasses work?

Using anti-blue light lens film reflection technology, the glasses reflect harmful blue light, so the surface of the lens reflects blue light, and the substrate absorption technology of the anti-blue light lens will not reflect blue light. Anti-blue light glasses mainly reflect harmful blue light by coating on the surface of the lens, or absorb harmful blue light by adding anti-blue light factor into the substrate of the lens, to realize the blocking of harmful blue light. The blue light intensity emitted by the mobile phone screen was effectively suppressed by the use of anti-blue light glasses, compared with a portable spectrometer.



The Price of Progressive Lens

Under normal circumstances, the price of the progressive lens is different from the purchase merchant, region, brand, and quality, but the price of the progressive lens on the official website is between 30-85 US dollars.

How to Adjust Glasses If They Pinch Your Nose

In some cases, glasses will pinch your nose, so you also need to adjust them, too. If the glasses frames are metal, you should simply widen the plastic nose pads using your thumbs until the frames fit comfortably. If the glasses frames are plastic, you should soak the arms of your glasses in warm water for 30-60 seconds, and gently apply upward and outward pressure on the end of the arms to get a more relaxed fit.

After that, your glasses will become more suitable.

Unfortunately, not all glasses can be adjusted by yourself at home. You can’t adjust some glasses which are based on the material of your glasses. For example, the glasses with the following material can’t be adjusted at home:

1. Aluminum alloy.
2. Memory plastic.
3. Titanium or memory titanium.

If your glasses are made of these materials, you can’t adjust them by yourself at home. If something goes worse, you need to buy a new pair of glasses. It is also risky to adjust the rimless or semi-rimless glasses by yourself at home.

As for how to tighten glasses or how to adjust glasses, you may have brief knowledge after reading this post. If your glasses are already broken or you want to get a pair of new glasses, you can try Koalaeye Optical, which is cheap and has a free shipping service.
