Aspherical Lens vs Spherical Lens
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 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 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.
