Special glasses reduce age-related visual impairment. A healthy human eye can see with an astonishing resolution of 25,000 ppi, a density that no electronic display has ever matched. Until now. Enter a Swedish research team that, with the help of tungsten oxide, has reduced pixel size to 560 nanometres. Corresponding to the size of one light-sensitive receptor cell in...

New glasses make blind spots visible again. In Australia, however, a research team is focusing on how to treat retinal diseases such as macular degeneration in the early stages of the condition. Preferably without the need for the injections. Lipo-soluble pigments from Gac fruit were integrated into a solution similar to eye drops. Using nanotechnology allowed the pigments -...

A smart pen deciphers Braille characters. But participating fully in digital life remains a challenge for those with no or limited vision. Enter a New York-based research team and its sparkling idea. The team’s square display contains 100 evenly arranged circular silicone sheets, each measuring 2mm in diameter. The sheets can be made to pop up within 0.24 milliseconds...

Smart glasses can protect blind people from collisions. Dogs are not immune to losing their sight either. Which is why Texas-based students are focusing on a solution that will stop blind dogs injuring themselves while out playing or walking. Their innovation: a smart vest with a hood. Attached to it at eye level are two cameras, with 8 vibrating...

Herbs and spices can aid memory and indigestion. Now, a blind female chef is aiming to make cooking safer for blind or vision-impaired people. In a series of accessible videos, she provides tips, cooks different recipes and introduces helpful tools. Like measuring spoons with tactile raised dots that make it easier to get quantities right. Or a ceramic coin...

A digital pen can detect and translate Braille in real time. Now, a Swiss startup has developed smart glasses to help blind people or those with limited vision detect obstacles and move around safely. Two radar sensors in the frames, which run for six hours on a single charge, scan the area above chest-level. An algorithm then analyses the...

Special lenses reduce the likelihood of epileptic attacks. Novel hearing glasses make for more inclusive conversations. Now, a New York-based company has developed smart glasses for vision-impaired people or those with retinal diseases like age-related macular degeneration. The trick? Two cameras in the frames record the field of vision, while two inward-facing cameras capture the eye and its movement....

Blind people can now navigate buildings more easily. Still, reading texts in braille requires training and a highly developed sense of touch. According to a Chinese research team, however, this role could soon be performed by a digital pen. The team developed a soft, thin film with an embedded fibre optic sensor, which uses light to feel. Like human...
