What color lenses are good for driving?

The optometrist reminded us that it is not advisable to choose pink, purple, light blue, and other colors with obvious decoration effects for driving sunglasses. These colored glasses basically cannot protect the eyes. In addition, they may change the color and cause chromatic aberration. Generally speaking, you should wear brown and gray glasses when driving. The brown lens can filter out a lot of blue light, which can effectively improve visual contrast and clarity. The gray lens can absorb any color spectrum in a balanced manner and will not produce obvious chromatic aberration after wearing.

Nowadays, the colors of lenses for sunglasses on the market are dazzling. Many people only consider whether they look good when choosing colors, and do not pay attention to the impact of lens colors on vision. When choosing sunglasses, we should not only pay attention to their decoration but also pay attention to their protective function for the eyes. We should avoid using blue lenses when driving because it will make us unable to distinguish the color of the traffic signal lights.


Clean your glasses correctly.

The dust of the lens will be washed (lightly), and then use a neutral detergent (cleaner) to clean. You can also buy professional glasses cleaning fluid, finally clean by water, and then use a professional glasses cloth to wipe. If the lens is covered with dust and particles before wiping, it is best to wash it with water and then gently dry it with a cloth.



The extraction of titanium

Nowadays, the commonly used extraction method is the reduction method of titanium tetrachloride. Compared to copper and zinc, although high in content, much more expensive.

Benefits of Progressive Lenses

Because the degree is gradual, the replacement of the adjustment effect is increased step by step according to the shortening of the close distance. There is no adjustment fluctuation, which is not easy to cause visual fatigue. Clear vision can be achieved at all distances in the visual scope.

Whichever you choose, a clear frame will help improve your style.

These frames vary from heavy traveler style to a more elegant corner frame to balance out your facial features. No matter what color or hue you choose, these clear frames show off your personality.
