Which sunglasses are best for driving, polarized sunglasses or non-polarized sunglasses?

Polarized and non-polarized sunglasses are the same in the ability to protect against ultraviolet rays. But when you work as a driver, in addition to the front of the sun, sometimes there are highway road reflective lights, other car body reflective lights, and so on. Glare will make people's eyes uncomfortable and fatigue, and affect the clarity of vision, stimulating the eyes. Polaroid lenses can filter out light from different angles, so when you driving, is best to wear polarized sunglasses.


Contact Lens Material - PHEMA material

It is the earliest material used in the production of contact lens hydrophilic material. The main advantage is water absorption, with a water content of about 38%. The material is soft, but its disadvantage is only partial oxygen permeability.



Bertoni polarized glasses

Bertoni polarized night vision driving glasses are made of strong, flexible, durable, and ultralight polycarbonate. Yellow polarization increases contrast, improves visual acuity, and filters out blue light. They are great for drivers, cyclists, and winter sports enthusiasts. The driving glasses with polarized yellow lenses block glare from headlights, reduce night driving glare, improve night vision, and improve color clarity and visual clarity.

What effect does a lens with the hard film have?

In order to improve the wear resistance of the lens, it is necessary to coat the surface of the lens with hard film. At present, silicon atoms are used to stiffen the membrane, that is, the stiffening solution containing organic matrix and inorganic superfine particles including silicon element is used to make the hard film have toughness and hardness at the same time. Because the common resin lens is far easier to wear than the glass lens, so the addition of hard film is mainly used for resin lens. It is usually applied to the front surface of the lens, and the anti-wear ability of the resin lens with the film will be enhanced a lot, and the light permeability will be strengthened.


What is blue light?

Blue light is an important part of natural light, and it is visible light with a wavelength of 400nm-500nm in the spectrum. Blue light can be divided into short-wave blue light (harmful blue light) and long-wave blue light (beneficial blue light). Short-wave blue light harms people’s vision and causes specific diseases, while long-wave blue light helps people maintain normal physiological functions, regulate biological rhythms, and treat specific diseases.

Blue light can be seen everywhere in daily life. In addition to blue light in the sun, electronic products such as TVs, computers, mobile phones, ipads, and LED lights also produce blue light in our daily.

What Are Colorblind Glasses?

Colorblind means that you can’t see the depth or richness of certain color shades. Colorblind glasses are eyeglasses with specially tinted lenses that help a colorblind person to see colors more accurately. Colorblind glasses do not cure color blindness or produce 100% normal color vision. But they enhance and partially correct certain color vision deficiencies of colorblind individuals.

Color blindness is common among people, especially in men. Blindness is an inherited condition, but can also be acquired. It can also occur if the eyes are damaged due to injury or from another disease that affects vision.

Colorblind glasses claim to assist with detecting differences between colors. They also claim to add additional vibrancy to the colors that people with color blindness may not fully experience.
