Patent Application
20120140307
The invention relates to windshield and windows installed to a vehicle for protecting operators and passengers of vehicle and items in the vehicle. The windshield and windows are made of photochromic materials made of Silver Halide or Silver Chloride. The photochromic windows are not transparent; specifically they filter out UV light. This does not represent a problem because the human eye does not see in the UV spectrum. The windows will begin to clear as soon as they are away from UV light and will be noticeably lighter within two minutes and mostly clear within five minutes. However, it normally takes more than fifteen minutes for the windshield/windows to completely fade to their non-exposed state.
The switching speed of photochromic dyes is highly sensitive to the rigidity of the environment around the dye. As a result, they switch most rapidly in solution and slowest in the rigid environment like a polymer lens.
A study by the Institute of Ophthalmology at the University College London has suggested that even in dark conditions; photochromic windows can absorb up to 20% of ambient light. Ambient lighting can refer to the available light in an environment.
With the many external and internal environmental factors when driving a vehicle, this invention will revolutionize the driving experience. Below depict the many safety and benefits of the invention:

Global warming
Climate is hotter
Need for skin protection is higher
Higher risks of skin cancer
It can be easier at night time for police to look into cars when looking for suspicious activity
