The harm of blue light to the eyes
Blue light is a high-energy light with a wavelength between 400-450 nanometers, especially short wave blue light (415-455 nanometers), which poses the greatest harm to the eyes. Blue light can penetrate the crystalline lens directly to the retina, producing free radicals that cause the decline of retinal pigment epithelial cells, leading to visual impairment, which is usually irreversible. Children and diabetes patients have lower resistance to blue light and are more vulnerable to blue light damage.
Advantages of anti blue light lenses
Reduce eye fatigue
Effectively filter harmful blue light, alleviate eye fatigue and dryness caused by long-term use of electronic products.
Protect vision
Prevent blue light from damaging the retina, reduce the risk of vision loss and eye diseases.
Personalized customization
Providing multiple functions and material choices to meet the needs of different groups of people.
Difference from regular lenses
Lens material
Anti blue light lenses reduce the damage of blue light to the eyes by adding special chemicals, while ordinary lenses do not have these additional chemicals.
Blue light filtering effect
Anti blue light lenses can effectively filter out high-intensity short wavelength light, reducing eye fatigue and photophobia; Ordinary lenses do not have this function.
Color change
Some anti blue light lenses may appear light purple or blue under strong light irradiation to indicate their anti blue light function; Ordinary lenses do not experience this situation.
Frequently Asked Questions
What is blue light and why is it harmful to the eyes?
Blue light is high-energy visible light with a wavelength between 400-450 nm. Short-wave blue light (415-455 nm) is especially harmful because it can penetrate the lens directly to the retina, generating free radicals that cause visual impairment, which is often irreversible.
What are the primary benefits of using anti-blue light lenses?
Anti-blue light lenses help reduce eye fatigue and dryness from digital screen use, protect the retina from long-term light damage, and provide custom options to suit various vision needs.
How do anti-blue light lenses differ from regular lenses?
Unlike regular lenses, anti-blue light lenses contain special chemicals that filter high-intensity short-wavelength light. They also may display a light purple or blue reflection under strong light to show their active filter coating.
What materials and refractive indexes are available?
These lenses are available in refractive indexes of 1.553, 1.597, and 1.667. They are manufactured using high-quality materials including Resin, Acrylic, MR-7, and MR-8.
Who is most vulnerable to blue light damage?
Children and diabetes patients have lower natural resistance to blue light, making them more vulnerable to light-induced retinal damage. Anyone using digital screens for long periods can also benefit significantly from these lenses.
