Blue light

A blue light filter lens is a type of lens that is designed to reduce the amount of blue light that reaches your eyes. Blue light is a high-energy light that is emitted by electronic devices such as smartphones, tablets, and computer screens, as well as by fluorescent and LED lights.

Excessive exposure to blue light can have negative effects on your eyes and overall health. It can cause eye strain, dryness, and fatigue, and may even disrupt your sleep patterns. Blue light filter lenses work by selectively blocking or absorbing a portion of the blue light spectrum, reducing the amount of blue light that enters your eyes.

These lenses are typically made with a special coating that filters out blue light while still allowing other colors to pass through. Some blue light filter lenses have a yellow or amber tint, which helps to enhance contrast and reduce glare. This can be particularly beneficial for people who spend long hours in front of digital screens or in environments with harsh lighting conditions.

Blue light filter lenses can be incorporated into prescription glasses, sunglasses, and even non-prescription eyewear. They are available in various lens materials and designs, including single vision, bifocal, and progressive lenses. Some lenses also offer additional features such as anti-reflective coatings to further reduce glare and improve visual comfort.

Overall, blue light filter lenses provide a solution to mitigate the potential negative effects of blue light exposure, promoting healthier and more comfortable vision, especially in today's digital age.
