The main use of color-changing lenses

Since the color-changing lens has many of the above-mentioned excellent properties, this lens has become a high-tech product integrating multiple functions. Its main uses include the following aspects:

1. Dual-purpose mirror for vision correction and sunshade

The luminosity range of the color-changing resin lens currently on the market covers a variety of luminosity such as myopia, presbyopia, astigmatism, progressive multifocal and bifocals. Because of its high transmittance to visible light when it is in a transparent state, it can be used for vision. For correction. At the same time, it can be used as sunglasses in the sun, so it is very convenient to use one lens for two purposes. This is currently the largest use of color-changing lenses.

It needs to be particularly emphasized that many people in the society, including some people in the optical industry, still have varying degrees of misunderstandings about color-changing lenses. They think that color-changing lenses are only used in the summer high temperature season and are mainly used as sunglasses. Therefore, the main sales season is summer. In fact, this kind of thinking is not comprehensive. In fact, color-changing lenses are equally important to the eyes throughout the year, because the ultraviolet rays of the sun are relatively strong throughout the year, and even the ultraviolet rays around noon in winter can cause greater damage to the eyes. , Wearing a color changing mirror should be the most convenient and practical.

2. Used as protective goggles

Color-changing lenses can also be used in many special occasions, such as making ski goggles, protecting against wind and sand in the wild, climbing, fishing, swimming, etc. Because the intensity of ultraviolet rays in snow, mountains, and water is much stronger than ultraviolet rays in general occasions, the damage to the eyes is particularly serious. At the same time, people in these occasions must ensure that the eyes have sufficient clarity, and the color will change at this time. The lens can meet these various requirements.

3. For fashion mirror

In addition to being used for sun shading, colorful color changing mirrors and double color changing mirrors also have a strong beautification effect, so they are mostly used for fashion mirrors, and the market prospect is extremely broad.

4. Used as car driving mirror

There is often strong light interference when driving a car. At this time, if you wear a pair of driving glasses with dual functions of polarized light and photochromic, you can operate freely in various light conditions. It is worth noting that choosing color-changing lenses with too shallow discoloration depth may not achieve the purpose of shading under high temperature conditions in summer. Therefore, it is recommended to choose color-changing lenses with a discoloration depth of more than 70% when used in summer, otherwise, you can choose a discoloration depth below 50% in winter. For the color-changing lens, it is best to choose a color-changing lens with a depth of more than 60% when used throughout the year. In addition, some specially designed color-changing mirrors are also used to correct some people's eye diseases.
