Lens refractive index
The refractive index of a lens is the ratio of the propagation speed of light in a vacuum to the propagation speed of light in the lens material. It reflects the ability of the lens to refract light. Currently, the mainstream lens refractive indexes on the market include: 1.56, 1.61, 1.67, 1.74, etc. Under the same prerequisites, the higher the refractive index of the lens, the thinner and lighter the lens.
Blue light blocking lenses
Protect your eyes from your everyday tasks in front of your computer and increase your productivity at both work and play. HPglasses' anti blue light lenses, are good for those who spend a good amount of time in front of their laptops and mobile devices. These lenses block out harmful blue light that emits from electronic devices and prevent them from entering our eyes. Blue light blocking glasses may help to reduce eye fatigue, dryness or other irritations caused by the harmful blue light!
Tinted lenses
Tinted lenses can be dyed on lenses with refractive power. Tinted lenses can effectively reduce the intensity of glare, ultraviolet rays and other light, reduce the damage of light to the eyes, prevent people from long-term exposure to strong light and cause eye fatigue, achieve real protection, and increase the decorative effect of glasses.
Photochromic lenses
What Are Photochromic Lenses? Photochromic lenses are lenses that stay transparent indoors, but darken when exposed to ultraviolet light from the sun. Essentially, they provide the benefits of glasses and sunglasses in a single frame.
Photochromic lenses are ideal for people who need to wear glasses all of the time. The two main purposes of photochromic lenses are to protect your eyes from UV light and to eliminate the need for a separate pair of prescription sunglasses. The lenses provide complete protection from UVA and UVB rays at all times
FOGLESS lenses
Our FOGLESS lenses can keep your glasses clear in different high humidity environments. FOGLESS coating technology uses the ion vacuum coating principle and magnetic control of electrochemical processes to add a transparent, highly hydrophilic layer to the lens anti-reflective coating.
Scenarios include kitchens, bathrooms, or wearing masks for long periods of time, and frequent temperature changes. These types of scenes can cause a layer of water vapor to form on the lenses, greatly affecting vision. Equipped with FOGLESS lenses can help you get rid of these troubles.
