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
1. Why is short-wave blue light particularly harmful to the eyes?
Short-wave blue light with a wavelength between 415-455 nanometers carries high energy. It can bypass the eye's natural crystalline lens and penetrate straight to the retina, generating free radicals that cause the decline of retinal pigment epithelial cells. This process can lead to irreversible visual impairment.
2. Who should be most cautious about blue light exposure?
Children and individuals with diabetes have a significantly lower natural resistance to blue light damage, making them much more vulnerable to retinal strain and vision issues from digital screens.
3. How do anti-blue light lenses differ chemically from regular lenses?
Anti-blue light lenses are manufactured by adding specialized chemical compounds to the lens material that selectively absorb or block harmful blue light wavelengths. Regular lenses do not contain these protective additives.
4. What specifications and materials are available for these lenses?
Our 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, with Abbe values ranging from 32 to 42, and diameters of 65, 70, 72, or 75mm.
5. Will my anti-blue light lenses change color under light?
Yes, some anti-blue light lenses are designed to display a subtle light purple or blue reflection when exposed to strong light sources, which indicates that the blue-blocking protective coating is active.
6. What protective coatings are applied to these lenses?
The lenses can be customized with various advanced optical coatings, including HMC (Hard Multi-Coat), SHMC (Super Hard Multi-Coat), specialized Blue protective coatings, and standard Green coatings to enhance durability and clarity.
