They have become a new type of glasses frame material. So that the wearer will no longer wear traditional overweight glasses, with no long-term pressure on the bridge of the nose caused by muscle oppression, and another discomfort.

Especially the high-end business elites praise pure titanium frame. No matter from the material, lens frame, suitable crowd, they can say to be an especially good choice!
Confirm the optometric data
It is necessary to confirm the accuracy of optometric data. If you stay up late or look at the phone or computer for too long before the optometry, leading to visual fatigue, it will increase the degree. But if you can let your eyes have a good rest, and then take optometry, the degree may be restored to the original situation, so you need to know the state of optometry, to check if it really had increased in degrees.

Can Pinhole Glasses Improve Your Vision?
The most important question may be whether the pinhole glasses improve your eyesight and some people may have this trouble. Some people say pinhole glasses can improve the vision of nearsightedness or astigmatism. But there is no evidence to prove that.
Although pinhole glasses can improve vision to some extent, they are not practical for everyday use. Pinhole glasses are designed to block part of your direct vision and restrict peripheral vision. They would cut the amount of light entering your eyes so as to reduce the visual quality of an image. Hence, it would be not recommended to wear pinhole glasses in daily life.
Blue light in electronic products
In addition to the blue light that exists in natural light, LED energy-saving lamps, fluorescent lamps, computer monitors, mobile phones, and other digital products will emit blue light because of the use of light-emitting diode LED technology. Some people think that blue light hurts the eyes because blue light is not absorbed by the cornea and lens like ultraviolet light. The blue light can pass through the refractive medium of the eye to reach the retina, and then be absorbed by the pigment epithelium of the retina, which will cause aging and functional degradation of the retina over time.
The eyes also have many protection mechanisms, such as squinting, pupil contraction, lutein contained in the macula of the retina, and the retina's own antioxidant repair mechanism, which protect our eyes from blue light damage. And after scientific testing, it is found that the blue light emitted by electronic products is only several hundredths of the intensity of blue light in natural light. This means that as long as the electronic products are not used continuously every day (for example, more than 8-10 hours a day), the blue light will not cause obvious damage to the eyes.
