Vision

An upcoming wearable device for the legally blind could help them navigate public and outdoor spaces independently, acting as 'glasses' that guide them through their surroundings. Maker .Lumen is accepting reservations now.

A team of researchers at Rice University has developed a haptic feedback vest and camera system for a blind dog known as Kunde. The vest helps guide the dog through daily obstacles and the hope is that it will soon do the same for other pups.

It certainly sounds like something from a new sci-fi series, but a power-free set of contact lenses impregnated with nanoparticles has proven successful in allowing humans to see what has previously been invisible – even when their eyes are closed.

It’s not always to picture what’s going on while listening to sports on the radio – so spare a thought for vision-impaired people who don’t have options. Now they do: meet the OneCourt, a haptic feedback device that works like braille for sports.

Elon Musk says Neuralink's BlindSight eye implants "ultimately may exceed normal human vision" – but researchers now contend that this is highly unlikely, and new videos show what the world will look like through direct pixels-to-neurons imaging.

Scientists have developed a new type of lens that creates multiple focal points, which could make for glasses or contacts that provide a clearer view over a range of distances. The secret? Making the lens a spiral shape.

The lenses in our eyes stiffen as we age, making it harder to switch focus between different distances. But autofocus systems are now getting so compact and efficient that they fit in a set of glasses – provided you don't mind looking a bit dorky.

Inspired by bats’ use of echolocation, researchers have developed smart glasses that transform visual information into unique sound representations that enhance the ability of blind and vision-impaired people to navigate their surroundings.

In fast-paced sports such as tennis, keeping your eye on the ball – and on your opponent – is essential to success. The FalconFrames wearable was designed with that fact in mind, as it's claimed to help boost its user's neuro-visual skills.

Sony has paired with QD Laser to create a retinal projection camera kit. By bypassing the outer layers of the eyes, the kit allows those who would otherwise have difficulty doing so see and capture the world around them.

One of the leading causes of blindness, age-related macular degeneration causes the center of an older person's vision to become blurry or even completely absent. Arges glasses are designed to help, by relocating the unseen images.

DARPA is starting a program to develop a new multispectral Enhanced Night Vision (ENVision) system for the military that replaces today's heavy night-vision goggles with ones that are as light and compact as a pair of eyeglasses.
