How to Test Computer Glasses (Clear Glasses)

First, we will show you how to test computer glasses with clear glasses.

1. Ask for Blue Light Glasses Brand Spectrum Report

To find out whether your blue light glasses are the best computer glasses, you should contact the company you bought them from and ask for a spectrum report. It will show you how much blue light your computer glasses can block.

After sending the spectrum report to you, you should make sure that your computer glasses are able to filter at least 30% blue light, otherwise, they are unsafe.

2. Use the Lens Reflection Test

As for how to test computer glasses, you can use the lens reflection test. You can see what color the light is that reflecting off the lenses.

If it reflects the blue light, they are filtering some blue light. If the reflection is violent or purple, the computer glasses may be not effective.

This is a good way for you to perform a blue light test at home.


How to buy contact lenses online?

Choose the right contact lens for your situation. Base arc and degree need to be added in the hospital or optician shop to determine. Try not to buy according to the framed degree. Some businesses claim to have the lenses having South Korea's silicone hydrogel, with annual throwing. They are not to be believed, because the material characteristics of the silicon hydrogel are not capable of making long-time discarded type lenses. There are a lot of things to pay attention to in order to properly wear contact lenses. For example, a medical optometry sheet is the premise of attention. Each pair of contact lenses is marked on the package of the basic arc, diameter, water content, diopter, and other parameters. Only according to the optometry sheet, you can choose the correct basic arc, diameter, and diopter. At the same time, there is a certain distance between the glasses and the cornea.



Suggestions for Using Varifocal Glasses

If it is difficult for you to get used to the new varifocal glasses, here are some suggestions for you.

1. Wear the varifocal glasses consistently so as to let your brain learn how to use them.
2. The most common accident is tripping when getting used to new varifocal glasses. So, you can mix up your routine to keep your brain active and prevent you from tripping up.
You can also ask those who wear varifocal glasses to give you some advice.


Benefits of wearing blue light blocking glasses

  1. Use blue light blocking glasses to relieve eye discomfort.

Excessive use of the device can cause computer vision syndrome or digital eye fatigue. Glasses with blue light filtering technology can enhance your concentration and reduce eye fatigue, thereby making your eyes feel less tired and improving work efficiency. Another way to reduce eye strain is to ensure that you stay away from the screen regularly.

  1. Sleep better with blue light blocking glasses

One of the more surprising effects of touching the screen is that it may have a negative effect on sleep patterns. Blue light has a high energy frequency, which can increase alertness and delay the body's release of melatonin, which helps induce sleep. Generally speaking, we should all avoid using Blu-ray devices one to two hours before going to bed. Anti-blue light glasses can reduce the impact of blue light, allowing you to use your device before going to bed and still have a good night's sleep. However, the best option is to put down the screen before going to bed.

  1. Reduce the possibility of AMD

Age-related macular degeneration (AMD) is the main cause of blindness. Anti-blue light lenses can help avoid or delay this situation by preventing blue light from affecting your eyes.

Computers, TVs, mobile phones, and tablets all emit blue light. Even with long-term exposure, the blue light emitted by these devices may not be enough to cause damage to the eyes or vision. However, further research is needed to confirm whether the blue light emitted from these devices is harmful. Experts are also uncertain whether blue light glasses can help symptoms associated with increased screen exposure. Ophthalmologists suggest that eye fatigue, headaches, and lack of sleep may be related to computer vision syndrome, rather than blue light exposure. For eye health, wearing blue light blocking glasses is not enough, we still have to develop good eye habits.



Titanium frame machining is complicated.

The elastic modulus of titanium alloy is small, which is easy to produce large deformation, springback, distortion, and vibration in cutting, resulting in poor geometric shape and accuracy of the workpiece. As the surface roughness increases, the tool wear increases. The thermal conductivity of titanium alloy is poor and its thermal conductivity is small, 1/6 of that of 45 steel, so the high heat generated in processing cannot be effectively diffused. It is even harder to use titanium to make glasses. The frames are very thin and a lot of fine work is demanded. It's definitely a challenge for titanium, which is pretty difficult to work with. In addition, titanium alloy frames involve titanium alloy welding technology, which is more difficult.


How to Adjust Crooked Glasses

If one side of your frame looks higher than the other, you need to adjust the arms of your glasses. So, how to adjust glasses?

If the right side is higher than the left, you need to gently bend the left arm down at the hinge or where the arm bends behind your ear. If the left side is higher than the left, so just do the same action on the opposite side.

When adjusting crooked glasses, you need to adjust frames a little bit at a time to avoid overcompensating and possibly damaging your glasses. You can run the arms under the warm water but do not running the warm water over the lenses because it will affect the lens coating.

Computer Protective Glasses

With the popularity of televisions and computers, electromagnetic radiation has become the No.1 killer of vision. The invention of radiation protection glasses is even more popular, and its market is also widely optimistic.

The lens design of the computer protective glasses has no side effects on vision. Refined with a high-tech vacuum ion coating, it can block 0% electromagnetic waves. The lens contains anti-radiation substances and has the function of absorbing positive charges. It can absorb low-frequency radiation microwaves and avoid potential eye fever, headache, fatigue, dryness, and other adverse symptoms caused by electromagnetic wave radiation. The penetration and absorption function of different light can resist radiation and glare, and the user will obviously feel clear and natural vision after wearing it. At present, there are mainly anti-blue lenses and anti-fatigue lenses, which can effectively prevent blue light radiation and relieve eye fatigue.
