Space Telescope Optics Aids Design of Eye-Saving Light Bulb

Throughout its existence, NASA has made many amazing discoveries in the field of optics that have led to improved eye care and eyewear applications on Earth. Innovations such as laser eye-tracking for LASIK vision-correction procedures, eye trackers that enable people with severe disabilities to communicate and control their environment using only their eye movements, and scratch-resistant and radiation-blocking lenses are just a taste of the Space Agency's optical accomplishments.
