Aspherical Lens vs Spherical Lens
There are significant differences between Aspherical lenses and spherical lenses in multiple aspects, mainly including design principles, visual quality, wearing comfort, lens appearance, and price.
Blue Cut Technology
Blue light with a wavelength between 415 and 455 nanometers is short wave harmful blue light, which poses the greatest threat to the retina. It can penetrate the crystalline lens directly to the retina, causing the decline of retinal pigment epithelial cells and ultimately leading to irreversible visual impairment.
- 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.
- Fatigue Reduction: 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.
- Sleep Quality Improvement: 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.
Anti blue light glasses cannot completely filter out all blue light, nor can they replace correct eye habits and scientific eye care. Wearing anti blue light glasses for a long time while watching electronic products may still cause eye fatigue, so it is necessary to rest your eyes appropriately and pay attention to eye hygiene.
Oil Pollution Prevention
The anti oil function of oil resistant lenses is mainly achieved through the organic hydrophobic film layer on their surface. This film layer can reduce the contact area between water and oil and the lens, making it difficult for oil and water droplets to adhere to the surface of the lens. This makes the lenses much easier to clean and maintain over long periods of use.
Frequently Asked Questions
Q1: What are the 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 material. It features a diameter of 65/70mm and comes with an HMC Green Coating.
Q2: Why should I choose an Aspherical lens over a Spherical lens?
Aspherical lenses significantly reduce edge distortion and are thinner in profile compared to spherical lenses. This provides a more realistic visual experience and helps reduce eye fatigue during extended wear.
Q3: How does the Blue Cut technology protect my eyes?
It utilizes double protection technology: a coating technology that reflects and absorbs harmful blue light, combined with substrate absorption that filters blue light directly within the lens core. This prevents harmful wavelengths (415-455nm) from reaching the retina.
Q4: Can wearing anti-blue light lenses improve my sleep?
Yes. Exposure to blue light at night inhibits melatonin secretion, which disturbs sleep patterns. Anti-blue light glasses reduce blue light intake, helping to normalize melatonin levels and improve sleep quality.
Q5: How does the oil pollution prevention coating work?
The lens features an organic hydrophobic film layer that minimizes the contact area for water and oil. This makes it highly resistant to smudges and fingerprints, ensuring the lens is easy to wipe clean.
Q6: Do anti-blue light glasses replace healthy eye habits?
No. While they significantly reduce screen glare and strain, they do not block 100% of all blue light. Wearers should still take regular eye breaks and practice proper eye hygiene.
