They’re heavily promoted. Your optometrist may even prescribe them. But when we looked at the evidence, this is what we found.
Why is it so difficult to swat a fly? A team of insect experts explains how a fly’s sophisticated vision allows it to quickly react to visual cues.
There’s more to reindeer than meets the eye.
Orthokeratology involves wearing a specially designed rigid contact lens overnight. There’s good evidence it can help slow the progression of myopia. But like all treatments, there are risks, too.

Some viruses can hide out in the body and reemerge at later times. Which viruses do this, and can the new coronavirus do this too?
Strategies to cure various types of blindness are looking more plausible after a series of recent breakthroughs using gene editing and gene therapy.
Having longer top eyelashes can enhance our ability to express our feelings and communicate with others. But the most significant reason we have them is to protect our eyes.
The causes of most inherited forms of blindness are unknown. Now more than 260 genes never before linked to eye development could lead to new therapies and diagnostics.
For roboticists looking to nature for inspiration on how animals see the world, there’s a tension between mimicking biology and capitalising on the advances in camera technology.
In an ant’s world, the smaller you get the less you can see. So how does that affect an ant’s ability to avoid hitting any obstacle as it walks about?
Stem cell treatments for eye disease always seem to be just on the horizon, but real progress is being made.
We’re used to thinking of our eyes detecting light as the foundation of our visual system. But what’s going on in other cells throughout the body that can detect light, too?
Glaucoma is a slow and silent progressive disease and the second leading cause of blindness, that requires early diagnosis.

Mammals’ ancestors had a third eye and the fossil record of its disappearance tells us the story of the evolution of one of our most important features: warm blood.
Is someone looking at you or are you just imagining things? A neuroscientist explains.
How does your brain deal with the ambiguous and variable visual information your eyes collect? Neuroscientists think it bets on what’s the most likely version of reality.
Lasers are getting smaller, cheaper and better. It’s time we were far more careful with them.
