Every driver has experienced the annoyance that bright sunlight presence when driving. In order to combat the issue I have come up with an idea that uses the same concept of transition lenses and applies it to cars. Instead of putting on sunglasses or putting down the shades, the car's mirrors will automatically detect the presence of UV rays and switch into a tint which helps deter sunlight from reaching your eyes.
The transition glass is photochromic. Photochromic means the glass will change from clear to dark in the presence of ultraviolet radiation, such as when exposed to sunlight. This glass is clear as any other glass but when exposed to sunlight will automatically turn into a tint which enhances the quality of vision by reducing glare, thereby lessen eye strain and fatigue, and improves contrast in all light conditions. The other benefit of this idea is that the whole process is automated leaving the driver to not have to do anything physical while driving.
Although the automobile industry is heavily focused on creating fuel efficient vehicles, the idea of creating transition glass for cars is an innovation that helps the driver be more safe. In the fast paced world we live in, drivers are constantly bombarded with outside factors such as a cellphone which keeps the driver's eyes off the road. Even a small thing like not having to look for you sunglasses or putting down the shades could help prevent an accident and potentially save a life.
