Smart Glasses

People with photosensitive epilepsy could soon be able to watch TV without worry. Scientists in the UK have created glasses that can block out specific wavelengths of light known to cause seizures.

Presbyopia is a common form of age-induced far-sightedness. Now a Stanford team has developed a pair of high-tech specs called autofocals, which use fluid-filled lenses, depth-sensing cameras and eye-tracking technology to make sure whatever a wearer is looking at stays sharp.

Prototype contact lenses have been created that have tiny telescopes built in to boost vision, and increase magnification in response to the user's eye winks. Originally designed to improve battlefield vision for soldiers, the new lenses may also help people with age-related macular degeneration.

Researchers at the University Teknologi Petronas, Malaysia, are developing a Smart Veins Locator, that will allow them to see a patient's veins through their skin, regardless of their skin color.
