How do they block blue light?

At Raval Eyewear, we use blue light lenses crafted with a specially developed coating designed to shield your eyes from the harmful effects of prolonged exposure to blue-violet light and LED screens.

Our high-quality CR-39 organic lenses block 100%UV of blue light below 410 nm and 43% of blue light in the 410-450 nm spectrum.

We use two advanced technologies:

• Reflection: The coating reflects blue light away.
• Absorption: The coating absorbs blue light to reduce its impact on your eyes.

The effects are immediate: your eyes feel more rested, relaxed, and comfortable when using digital devices.
