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 the harmful wavelength of blue light to the eyes?
Blue light is high-energy light with a wavelength between 400-450 nanometers. Short-wave blue light with a wavelength of 415-455 nanometers poses the greatest risk, as it can penetrate the lens directly to the retina and cause irreversible visual impairment.
Who is most vulnerable to blue light damage?
Children and diabetes patients have lower natural resistance to blue light, making them significantly more vulnerable to blue light damage than others.
How do anti blue light lenses protect your vision?
They effectively filter out harmful blue light and prevent it from damaging the retina. This alleviates eye fatigue, dryness, and reduces the long-term risk of vision loss and eye diseases.
What is the chemical difference between anti blue light lenses and regular lenses?
Anti blue light lenses are manufactured with special additional chemicals that absorb or filter out high-intensity short wavelength light, whereas ordinary lenses do not contain these chemicals.
What specifications and coatings are available for these lenses?
The lenses are available in refractive indexes of 1.553, 1.597, and 1.667. They are made of Resin, Acrylic, MR-7, or MR-8 materials, and can be customized with HMC, SHMC, Blue, or Green coatings.
Why do anti blue light lenses sometimes change color under strong light?
Some anti blue light lenses reflect or filter blue light in a way that makes them appear light purple or blue under strong light irradiation, which indicates that the protective filtering function is active.
