Night vision - wikipedia the free encyclopedia

Humans have lower affinity to night vision than many animals and in many cases it is not sufficient. Therefore, scientists have developed many types of night vision devices that helped creating the night vision concept. The traditional night vision goggles are too expensive and inconvenient. Therefore, the scientist are inventing new concepts, such as  night vision drops and night vision contact lenses.

Night vision eye drops 

Night vision eye drops might sound like a futuristic concept, but the first experiments have already been performed on a volunteer. He was able to retain the night vision and there were no side effects. Night vision eye drops are based on chlorine e6 that is present in marine organisms.
