One:the advantages and disadvantages of color-changing cycling glasses
There are many kinds of cycling glasses, one of the more common is color changing glasses, then color changing cycling glasses is good?
1. Advantages of color-changing cycling glasses
Color changing glasses protect our eyes by changing the UV and temperature in the environment.When riding outside, long-term exposure to ultraviolet light may cause eye diseases, and in serious cases may lead to cataracts and other eye diseases. Wearing color changing glasses can prevent ultraviolet light from entering people's eyes, prevent glare, provide comprehensive protection for the eyes and provide comfortable visual enjoyment for the eyes.
2. Disadvantages of color-changing cycling glasses
The price of colour-changing cycling glasses is relatively high, which is mainly caused by people's insufficient understanding of colour-changing glasses. Moreover, due to the large market demand, some fake and inferior colour-changing glasses produced by some illegal businesses enter the market. Such colour-changing glasses cannot protect the eyes, so we should pay attention to purchase them through regular channels.
In general, color-changing glasses are more suitable for cycling, but it should be noted that the color-changing effect of color-changing glasses will be affected by ultraviolet intensity and temperature and other factors, and its color-changing also needs time.
Two:Are color-changing cycling glasses useful under strong light
The color-changing cycling glasses add silver halide to the lenses, making the originally transparent and colorless lenses turn into colored lenses under strong light irradiation, which has a very obvious effect on protecting the health of the eyes.According to the principle of reciprocal change of light and color, the lens can change color when irradiated under strong light and fully absorb ultraviolet light.It has neutral absorption to visible light.Back in the dark, the lens will fade back to its original state of colorless transparency.
Color changing glasses need sunlight to change color, so they work even under strong light. On the contrary, in areas such as indoor, because there is no strong light, they will change to the original color.Color changing glasses are especially suitable for outdoor, indoor strong light and other places, which can prevent the sun, ultraviolet ray and other damage to the eyes.
However, it is important to pay attention to the use of color-changing cycling glasses. To buy high-quality color-changing cycling glasses, it is generally required to completely change color within 40 seconds of strong light irradiation. It is a better product to fade to a translucent degree within two minutes after leaving the sunlight.In addition, the color-changing cycling glasses purchased should be checked regularly under the sun, and special attention should be paid to whether the photosensitive color-changing depth of the lens is consistent, so as to avoid the situation of one dark color and one light color.
Thank you for watching.
