Which Glasses for Computer Are the Best?

There is no such a thing that one type of computer glasses can fit all or is the best for everybody. When selecting glasses for screen protection, the visual ability, personal preferences, the type of work, the distance between the computer user’s eye and the monitor, and other factors should also be considered.


Uvex Stealth OTG Safety Goggles

They provide more protection and coverage than other prescription safety glasses. Due to the full seal around the eye, these OTG safety goggles prevent chemical splashes, and bumps, and scratches, making them wonderful general-purpose safety goggles to wear over your prescription glasses. Dura-Streme's scratch-resistant coating helps keep the lenses crystal clear, which is especially important when wearing the underlying glasses.



How to repair rimless glasses?

First, insert the wire into a small hole in the glasses near the bridge. Pass it in and out near the bridge, then repeat the process on the other side near the temple. Once you have the thread locked, you can place the lens. Insert it into the frame and place the wire in the built-in groove. Tighten the wire so it holds the lens perfectly, then trim it to the left. Reinsert the lens into the rimless glasses. Do not try to force it back in. The best way is to cut the wires completely and replace them with new ones. Use the same process as replacing wires. To prevent glasses from popping out, tighten the wires regularly.


How do you identify the refractive index of lens?

In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.



Be sure to wear qualified glasses.

Many people are eager to buy glasses online without the necessary checks at a proper optical center for glasses. But, in reality, these tests are not only to replace glasses but to take responsibility for the safety of their own eyes. These cheap and inferior glasses will do a lot of harm to most myopic friends. If you wear unqualified glasses, it will cause visual fatigue, headache, dizziness, nausea, and other symptoms, vision loss. Severe cases can lead to amblyopia, strabismus, or other functional impairments.


What Should Be Considered When Buying Blue Light Glasses?

Be wary of “eye protection” claims. Some businesses advocate their anti-blue light products how miraculous.

Do not try the lens from the unknown lens manufacturer or lens factory. A professional lens factory needs more than ten years or even decades of accumulation, so do not be blinded by dazzling pictures and brand image.
