Blue light blocking lenses are a must-have item for anyone who spends a lot of time in front of screens. But did you know that there are two main types of blue light blocking lenses? Today, we'll take a closer look at UV420, a special material that makes blue light blocking lenses even more effective.
There are two main types of blue light blocking lenses:
1. Coated lenses use a coating to reflect blue light away from the eyes. This type of lens can block up to 40-50% of blue light, but it can also make images appear yellow or orange.
2. UV420 lenses are made from a special material that absorbs blue light. This type of lens can block up to 90% of blue light, and it does not cause images to appear yellow or orange.
UV420 lenses are superior to coated lenses in several ways:
1. They offer better protection from blue light. Coated lenses can only block up to 40-50% of blue light, while UV420 lenses can block up to 90%.
2. They do not cause images to appear yellow or orange. This makes them more comfortable to wear for extended periods of time.
3. They can also block other harmful wavelengths of light, such as HEV (high-energy visible light). HEV light is associated with a number of health risks, including eye strain, macular degeneration, and even cancer.
Overall, UV420 lenses are the best option for anyone who wants to protect their eyes from the harmful effects of blue light. They offer superior protection, are comfortable to wear, and can even help to reduce your risk of developing eye problems.
