Optical protective film is a special coating technology for glasses, which can effectively resist glare, blue light and other harmful ultraviolet rays. It is a transparent thin film layer that can be covered over various types of glasses, including nearsightedness, farsightedness, presbyopia, and sunglasses.

Glare, blue light, and ultraviolet light are all common problems in our daily lives. So, protecting our eyes is very important for our health. According to studies, if we are exposed to indoor or outdoor environments for a long time, glare and ultraviolet radiation can cause damage to our eyes and even lead to eye diseases such as cataracts and keratitis. Among these harmful rays, blue light is a light that has recently attracted the attention of the medical community and the public, because our electronic devices, such as computers, mobile phones, tablets, etc., will release a large amount of blue light, which will directly cause damage to our eyes.

Optical protective film is a special coating layer that can be covered with various functional film layers on the lens through different processes, so that it can effectively resist glare, blue light and ultraviolet light, thereby protecting our eyes.

1. Resist glare

Glare is a common problem in our daily lives. On highly reflective surfaces, such as water, mirrors, ground and snow, the reflection of glare can cause us to be unable to see a clear image and even affect our vision. Optical protective films can be used to resist glare by reflecting and/or absorbing light. By reflection, the protective film will reduce the reflection of light, so that there will be no spots or glare when we see the image; By absorbing light, the protective film filters out glare, making our vision clearer and brighter.

2. Reduce blue light

Blue light is an unavoidable light in our daily lives, however, if exposed to high intensity blue light for a long time, it can cause damage to our eyes, which in turn can lead to eye diseases such as macular degeneration. The optical protective film can be covered with a special film layer of light wavelength that can be sensed only through the human eye through a special coating technology, so as to protect our eyes and reduce the damage of blue light exposure to the eyes.

3. Filter UV rays

Ultraviolet light is one of the invisible killers in our daily life, long-term exposure to strong ultraviolet light will not only lead to skin cancer and sunburn, but also cause eye diseases, such as cataracts and other inflammation. Optical protective film can play a filtering effect by reflecting and/or absorbing ultraviolet light to protect our eyes from UV damage.

All in all, optical protective film is a powerful eye protection technology, which can effectively protect against glare, blue light and UV damage. In modern life, we are constantly exposed to electronic devices and outdoor environments, and these harmful lights can cause damage to our eyes. By wearing glasses with optical protective film, we can effectively protect our eyes and keep our eyes healthy and bright.
