With the development of science and technology, people can't live without electronics. Blue light blocking glasses have become popular due to reducing the harm of blue light. However, some people worry that does blue light blocking glasses affect vision? It depends.
According to the blue light rejection rate, blue light blocking glasses are roughly divided into four kinds on Eyekeeper, which are BB40, BB60, BB90, and BB98 series.
Glasses with BB40 lenses are also called blue light filters, which are hard to distinguish from glasses with clear lenses unless you put them on white paper. You will find the lenses are a little yellower than clear lenses in this way. Therefore, the vision with BB40 lenses is almost the same as usual. The BB40 lenses do not block blue color but most blue light. Models starting with UVR are blue light glasses with BB40 lenses on Eyekeeper.
The color of blue light blocking glasses with BB60 lenses is yellow, which is distinctively different from the clear lenses. They block 30% blue color and cause 20% color distortion. Models starting with TM or TMCG are blue light glasses with BB60 lenses on Eyekeeper.
The blue light blocking glasses with BB90 lenses are amber. They filter out 50% blue color and cause 30% color distortion, which means you will see a yellow world when wearing the blue light blocking glasses with BB90 lenses. The models starting with HP are BB90 lens glasses.
The BB98 has the darkest lens, which is orange. And it can block 90% blue color and even make your vision 50% color distortion. So this lens will affect your vision, especially in color. Models beginning with TM or TMCG are blue light glasses with BB98 lenses on Eyekeeper.
To summarize, blue light blocking glasses affect vision, which depends on the color of the lens. If you do not want them to affect your vision, BB40 lenses are a good choice. Blue light blocking glasses suit most people who have to work a long time in front of the screen. However, if your job requires you to be sensitive to color, blue light blocking glasses are not recommended.
