Vision

A surgical procedure to restore the power of sight to blind patients using their teeth is gaining traction around the world, with Canada opening its first clinic for this treatment. Here's how Osteo-odonto-keratoprosthesis works, and who it's for.

Eye injuries that damage the cornea are usually irreversible and cause blindness. But a new clinical trial has repaired this damage in patients thanks to a transplant of stem cells from their healthy eyes.

Scientists in the UK have successfully used gene therapy to restore some vision to legally blind children with an inherited retinal condition. All 11 children in the clinical trial saw improvements within weeks of a single surgical treatment.

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.

Scientists remain puzzled as to why some people taking popular weight loss and diabetes medications like Ozempic and Wegovy are losing their vision suddenly, highlighting that there's still so much we don't know about this life-changing class of drugs.

A clever new set of glasses may offer new hope to people with macular degeneration. By copying the structure of a fly's eyes, the specs are claimed to "fill in" the missing section of the wearer's view of the world.

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.

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.

CRISPR gene-editing has improved the vision of patients with a form of blindness in a Phase 1/2 clinical trial. The results give new hope to patients with the condition, and show that CRISPR could be put to use in humans to treat a range of conditions.

Blinking keeps our eyes moist – but we actually blink way more often than we need to if that was the only reason. Scientists have now found that the involuntary action plays a bigger role than we thought, helping us process visual information.

Imagine waking up one day and seeing every face distorted into demonic proportions. That’s reality for patients with a rare condition called prosopometamorphopsia (PMO), and a unique case study has now given us a glimpse through their eyes.

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.
