Aspherical lens & 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
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.

Frequently Asked Questions (FAQ)
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 available in diameters of 65/70. It is made of high-quality resin material and features an HMC Green Coating.
What is the visual advantage of Aspherical lenses over Spherical lenses?
Spherical lenses often cause distortion at the edges and look thicker, leading to eye fatigue. Aspherical lenses significantly reduce edge distortion, providing a more realistic visual experience and improving wearing comfort.
How do Blue Cut lenses protect eyes from harmful blue light?
Blue Cut lenses protect your eyes using coating technology to reflect or absorb harmful blue light and substrate absorption technology to filter out blue light entering the lens, preventing it from reaching and damaging the retina.
What is Double Protection Technology in anti-blue light glasses?
Double protection technology combines both coating technology and substrate absorption technology in a single lens to offer a more comprehensive and robust defense against harmful blue light.
How does the oil pollution prevention feature work on these lenses?
The lens surface features an organic hydrophobic film layer. This layer minimizes the contact area for water and oil, making it difficult for droplets to adhere to the lens surface, which makes cleaning and maintenance much easier.
Can anti-blue light lenses completely eliminate eye strain?
No, anti-blue light glasses reduce blue light stimulation and fatigue but cannot completely replace proper eye habits. It is still essential to take regular breaks and practice scientific eye care during prolonged screen use.
