These are the colours your eyes can’t see

From an early age, we’re lead to believe that the so-called colour spectrum contains all the colours out there. And it’s true, if you are only considering colours that are perceptible by a normal human eye. Colour is the limited range of light along the electromagnetic spectrum that humans can see. In other words, colours are the way your brain, and mine, by use of our eyes, interpret a stream of minute energy packets radiating at varying frequencies in a wave motion.… Read more

The incredible vision of a south-east African tribe

Our vision adapts to the world we live in. But natural evolution can only move so fast, and there’s no limit to the speed at which the world can change. So, when in just a few generations the average person’s day shifts from spending hours out in wide-open spaces, full of natural light, different colours and contrasts, and moving objects at varying distances, to sitting in an office in a city and staring at a computer screen all day, it’s no surprise… Read more

What do your eyes reveal about who you are?

Everyone has heard the saying “the eyes are the windows to the soul”. It’s been so overused in advertising and daily speech that it’s almost lost all meaning. But like most cliches, there’s a reason it has stuck around in the public consciousness. Mentioned in the bible in Matthew 6 22-23, and being very similar to proverbs in several languages, such as the French, ‘Les yeux sont le miroir de l’dme’, “The eyes are the mirror of the soul”, the saying bears a… Read more

Dolphins, eagles and other animals with better vision than you

When it comes to a lot of natural abilities, humans are by far top of the pile. We can use tools like cutlery and computers and surgical equipment to improve our lives and society as a whole. We can conceive complex, multidimensional ideas, and project into the future and think back long into the past. And when it comes to vision, well, we can see pretty well. We can perceive a decent range of the colour spectrum. We can see stars that… Read more

4 Misconceptions about your eye health

There’s an abundance of ideas and misconceptions about vision and keeping your eyes healthy out there. At best, they’re funny and harmless, like if you cross your eyes for too long they’ll stay that way. At worst, they can be damaging to your health. The big problem is, because there are so many, it can be difficult to know which are fact and which are fiction. To know what’s fake news and what’s legitimate, and ultimately how you can best look after… Read more

Do eye health supplements really work?

Health supplements are a modern invention. Yet, after a few minutes of browsing the shelves of Holland and Barratt or just your local supermarket, you could be fooled into thinking they’re essential for everyone to maintain a basic standard of health. Together, all products or supplements that aim to improve your health—multivitamins, protein powders, detox tonics, etc.—make up a multi-million-pound global industry. The fact is, they’re convenient, incredibly-well branded, and often promise for results that no vegetable or piece of fruit ever… Read more

Are glasses bad for your eyes?

Glasses as we know them today—framed lenses with sides, or temples, that sit on your face as opposed to being held up by your hand—have only been widely available for the last hundred years or so. Yet, by the sheer number of people who wear them today, the endless number of styles and shapes available, and the ease with which you pull them on and off and wipe a smear on the lens, you would think they’d been around forever. Playing such… Read more

Children and eye health care

Every single eye is different. It’s why retinal scanners are so good at identifying you from the crowd. But your eyes are so unique they’re also different from each other. Just take a moment to look in the mirror at each iris, the coloured part of your eye that controls the amount of light that hits your retina. No doubt you’ll see small, random patterns in one iris that appear completely different from the other. Even identical twins don’t share the same… Read more

What do your eyes say about your health?

The eye may, or may not be, the window to the soul. But the eyes are definitely a window into the body. Thanks to the connection with the optic nerve at the back of the eye, your eyes give doctors an exclusive look into your central nervous system. This is one reason why your eyes can often show the first signs of health problems and potential issues in the body. Everyone’s eyes are different. But there are certain common signs that you… Read more

Smoking and your eyesight

As a nation, we’re well aware of the risks associated with smoking. From respiratory and cardiovascular diseases to cancers and the accelerated ageing of your skin. Less is known, however, about the many ways that smoking is damaging to one of our most precious organs: the eyes. There are the obvious effects, like the discomfort, irritation, and dryness after spending a night in a smoke-filled club. But the way that tobacco smoke – a toxic mix of more than 7,000 chemicals and compounds – enters your blood… Read more
