The screen protector is a transparent plastic material covering the display, which reflects harmful blue light through a surface coating.

Many screen protectors have reflective problems. If you have a light or window behind you, it will turn your computer screen into a mirror.

Also need to pay attention to the transmittance of the protective laminate, if the transmittance is insufficient, it will affect the clarity of the screen.

In addition, the adhesion of some screen protectors to the display is not good, which causes the display to be blurred and the text and images cannot be seen clearly.

Because the screen protector panel must fit the size of the laptop, if you replace the laptop in the future, you may need to repurchase the screen protector panel.

Blue light filter glassesblue light filter for laptop

Blue light filter glasses reflect harmful blue light by coating on the surface of the lens, or use the principle of color bleeding, through the principle of optical complementary color, to infiltrate the blue complementary color yellow into the lens material and absorb the blue light by the pigment, thereby realizing the blocking of harmful blue light.

A good physical blue light filter should be based on reverting to natural light.

The blue light blocking rate cannot be too high or too low. Too low has no practical effect. Filtering blue light too much will lead to confusion in our circadian rhythm.

In addition, blocking too much blue light can also cause serious distortion and visual fatigue problems. The blue light blocking rate should be 60%~70%.

The downside of physical blue light filters is that they are expensive and are rarely made of durable materials, and you may end up having to replace them often.

After using the physical blue light filter, the color of the screen will be affected, especially the pictures.

However, the blue light filtering effect of the physical blue light filter cannot be adjusted. If you sometimes need to deal with some tasks that require high color fidelity, then you will find it very troublesome.

The use of software applications will not have such a problem, because it can adjust the blue light blocking rate.
