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 features a refractive index of 1.553, an Abbe Value of 34, and is made of high-quality resin material. It comes with an HMC Green coating and is available in diameters of 65mm and 70mm.
What is the difference between spherical and aspherical lenses? ▼
Spherical lenses produce significant distortion at the edges (especially for high prescriptions) and appear thicker, which can lead to eye fatigue. Aspherical lenses significantly reduce edge distortion, look thinner, allow you to see objects more realistically, and help reduce eye strain.
How does the Blue Cut technology protect the eyes? ▼
Blue Cut lenses filter out harmful short-wave blue light (wavelengths between 415 and 455 nm) that can damage the retina. They utilize coating technology to reflect blue light, substrate absorption to absorb it, or double protection combining both methods to safeguard the eyes.
Can wearing anti-blue light lenses improve my sleep quality? ▼
Yes. Exposure to blue light from electronic screens inhibits the secretion of melatonin, which disrupts sleep. Wearing anti-blue light glasses at night reduces blue light intake, helping to maintain normal melatonin levels and improve sleep quality.
How does the oil pollution prevention coating work? ▼
The lens surface features an organic hydrophobic film layer. This film reduces the contact area between the lens and oil or water, making it highly resistant to smudges and droplets. This makes the lenses much easier to clean and maintain.
