Aspherical lens & 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.
Spherical Lenses
Due to their design characteristics, spherical lenses will produce significant distortion at the edges, especially when the degree is high. The lenses may appear thicker in appearance, which can cause deformation or distortion when the wearer sees objects. Wearing spherical lenses for a long time can lead to eye fatigue or discomfort.
Aspherical Lenses
Significantly reduce edge distortion, allowing wearers to see objects more realistically and helping to reduce eye fatigue.
Blue Cut
The Hazards of Blue Light
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 visual impairment.
Which is irreversible: Anti blue light lenses use special technology to filter out some harmful blue light, thereby reducing the harm of these blue lights to the eyes.
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.
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. Make the lenses easier to clean and maintain.
Frequently Asked Questions
What are the technical specifications of the 1.56 Blue Cut Lens?
The 1.56 Blue Cut Lens has a refractive index of 1.553, an Abbe value of 34, and is made of high-quality resin material. It is available in diameters of 65/70 and features an HMC Green Coating.
How do Aspherical lenses differ from Spherical lenses?
Spherical lenses produce significant distortion at the outer edges, look thicker, and can cause eye fatigue. Aspherical lenses are designed to significantly reduce edge distortion, offering a more realistic view and superior wearing comfort.
Why is harmful blue light dangerous to human eyes?
Short-wave blue light with a wavelength between 415 and 455 nanometers directly penetrates the crystalline lens to the retina. This can damage retinal pigment epithelial cells, leading to irreversible visual impairment and eye strain.
What technologies are used in these lenses to block blue light?
These lenses utilize coating technology (a film that reflects/absorbs blue light) and substrate absorption (anti-blue light factors built into the lens material). High-end options combine both for double protection.
Can wearing anti-blue light glasses improve sleep quality?
Yes. Blue light exposure at night inhibits the natural secretion of melatonin. By wearing anti-blue light glasses to filter out blue light from electronic devices, you can help restore healthy melatonin levels and improve your sleep.
How does the oil pollution prevention coating work?
It uses an organic hydrophobic film layer on the lens surface. This layer minimizes the contact area for water and oil, preventing droplets and smudge adhesion, which makes the lenses much easier to clean.
