Nosy fish inspires help for the eyes

Presbyopia is a common visual condition, in which the eye's lens stiffens to the point that it can't focus on close objects. Glasses, surgery and regular contact lenses do help, but they also cause a loss in contrast, sensitivity and night vision. That's why scientists from the University of Wisconsin, Madison are developing an alternative – self-focusing contacts that are inspired by a fish.Read More

​New cataracts treatment restores infants' vision using stem cells

While you might generally associate cataracts with more mature patients, as many as three in every 10,000 children suffer from the condition, which can cause significant vision loss. Now, researchers at the University of California, San Diego (UC San Diego) have tested a new approach to tackling congenital cataracts, turning to existing stem cells to repair the patient lenses post-surgery, restoring vision.

Vitamin C-detecting sensor could assess eye injuries on the spot

Although any eye injury can be painful and upsetting, those that involve damage to the inside of the eye are the most serious. For people like battlefield medics or rural physicians, however, it can be difficult to judge the extent of such injuries without the resources of a hospital. That's why scientists from the University of Illinois have created OcuCheck – it's a portable sensor that assesses eye injuries based on the amount of vitamin C in the patient's tears.Read More

Implantable LCD eye lenses may make glasses obsolete

The potential for replacing aging or damaged eye lenses with artificial lenses that do more than just restore eyesight has long been recognized. With everything from telescopic capabilities to those with built-in heads-up displays, electronically-enabled synthetic lenses promise to bring useful cybernetic enhancements to the human body. In pursuit of this goal, one researcher at the University of Leeds is developing a unique, auto-focusing liquid crystal lens that may help cure age-related long-sightedness.Read More

Opternative's online eye-testing service returns prescriptions in 24 hours

Taking time out of your day to make an appointment and see an optometrist isn't always that agreeable, and that's before they blow those little puffs of air onto your eyeballs. But one Chicago-based startup has visions of making eye examinations a lot more accessible. Since 2012, Opternative has been developing an online eye tester that lets users obtain prescriptions for glasses and contacts from the comfort of the home or office. And now with clinical trial success under its belt, it's rolling the service out to the public.Read More

New study shows Peek eye test app works like a pro

Peek, the smartphone eye test app designed to improve eyecare in remote areas, has been found to be as accurate as traditional methods. According to a study published last week, tests with the app carried out between December 2013 and March 2014 produced levels of accuracy that were on a par with paper-based charts and expensive illuminated vision boxes found in clinics.Read More

Italian company hopes to market synthetic eyeballs

Imagine being able to see in black and white or with an Instagram-like filter, or to have what you see through your eyes transmitted wirelessly, simply by swallowing a pill. Or imagine having vision so sharp and accurate that your visual acuity is on par with the most sight-adept people in the world. Italian research studio Mhox hopes to one day make this a reality with its EYE concept, which would offer 3D bioprinted eyes that replace your existing eyeballs.Read More

Biohackers develop night vision eye drops to see in the dark

It sounds like something from a science-fiction movie, but a biohacking group in California has managed to develop eye drops that temporarily give a human being excellent night vision. The chemicals used are still very much at the experimental stage – this isn't something you'd want to try at home just yet – but the first trial has been a successful one.Read More

NASA seeks to understand vision changes due to microgravity

Having evolved under the pressure of Earth's gravity, it isn't surprising that our bodies experience adverse physiological affects after long periods in low-Earth orbit. NASA hopes that a new experiment, the Fluid Shifts investigation, set to launch to the ISS later this year, will shed light on the causes of vision loss and deformation of the structure to the eye often suffered by astronauts over the course of a stay aboard the ISS.Read More
