Frequently Asked Questions (FAQ)
What is the difference in material between anti-blue light lenses and regular lenses?
Anti-blue light lenses are manufactured by adding specialized chemical agents to the lens material to absorb or filter high-energy blue light. Regular lenses do not contain these additives and cannot filter blue light effectively.
What specifications and indices are available for these lenses?
These anti-blue light lenses come in refractive indices of 1.553, 1.597, and 1.667. They are available in materials such as Resin, Acrylic, MR-7, and MR-8, with diameters ranging from 65mm to 75mm.
Why does blue light pose a hazard to human eyes?
Short-wave blue light (415-455 nm) carries high energy that can pass directly through the eye lens to the retina. This generates free radicals that can damage retinal pigment epithelial cells, potentially leading to irreversible vision impairment.
How do anti-blue light lenses relieve eye strain?
By filtering out high-energy blue light and reducing glare, these lenses ease the visual stress and dryness associated with long-term exposure to digital screens, computers, and smartphones.
Do anti-blue light lenses change color under light?
Yes, some anti-blue light lenses exhibit a subtle light purple or blue reflection when exposed to strong light source. This is a visual indication of their active blue light filtering coating, which is absent in standard lenses.
