- Coating technology: A special film is coated on the surface of the lens, which can reflect or absorb some harmful blue light, reducing damage to the eyes.
- Substrate absorption: Adding anti blue light factors to the substrate of the lens can absorb the blue light entering the lens, further reducing the impact of blue light on the eyes.
- Double protection technology: Some high-end anti blue light glasses combine coating and substrate absorption technologies to achieve more comprehensive blue light protection.
- Anti blue light lenses can filter out some blue light, reduce the intensity of blue light, reduce the stimulation of blue light to the eyes, thereby reducing fatigue and making the eyes more comfortable when watching electronic device screens.
- Blue light can inhibit the secretion of melatonin and affect sleep quality. Wearing anti blue light glasses can reduce the intake of blue light at night, help increase the secretion level of melatonin, and thus improve sleep quality.
What are the key technical specifications of the 1.56 Blue Cut Lens?
The lens has a refractive index of 1.553, an Abbe value of 34, and is made of high-quality resin. It features an HMC Green Coating and is available in diameters of 65mm and 70mm.
What are the visual benefits of aspherical lenses over spherical lenses?
Aspherical lenses significantly reduce edge distortion, providing a more realistic visual experience and helping to decrease eye fatigue. Spherical lenses, conversely, often cause distortion at the edges, particularly for higher prescriptions, and can make objects appear deformed.
Why is harmful blue light dangerous to the eyes?
Harmful blue light with a wavelength between 415 and 455 nanometers penetrates the crystalline lens directly to the retina. This can lead to the decline of retinal pigment epithelial cells, causing irreversible visual impairment.
How do anti-blue light lenses filter out harmful light?
They use two primary methods: coating technology, which reflects or absorbs blue light via a surface film, and substrate absorption, which uses blue light-absorbing factors within the lens material itself. High-end lenses combine both technologies for double protection.
Can wearing anti-blue light glasses improve sleep quality?
Yes. Blue light inhibits the secretion of melatonin, which disrupts sleep. Wearing anti-blue light glasses at night reduces blue light intake, helping to maintain healthy melatonin levels and improve sleep quality.
How does the oil pollution prevention feature work on these lenses?
It is achieved through an organic hydrophobic film layer on the lens surface. This layer reduces the contact area between the lens and oil or water, preventing droplets from adhering and making the lenses much easier to clean and maintain.
