Believe it or not, your eyes can get sunburned, too, but it’s not the same as what happens to your skin. It’s a prolonged process that occurs over time. This doesn’t mean you should be applying sunscreen to your eyes, but wearing sunglasses can definitely help.

Although your retinas have red, green and blue colour receptors, the “red” receptor only detects yellow-green, and the “green” receptor detects blue-green. Your brain combines these signals and turns them into red.

A process called Troxler’s phenomenon causes static objects in your gaze to disappear if you stare at them for too long. Micro saccades stop this from happening.

Do you know what your eyes are made up of?
The eye is made up of three coats, enclosing three transparent structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera. The middle layer, known as the vascular tunic or uvea, consists of the choroid, ciliary body, and iris.

Slight vision changes are common for pregnant women to experience. If you notice that your vision has steadily changed or is periodically different, you’re likely experiencing refractive changes (changes in eye structure/shape) caused by fluid retention.

Did you know your child could get Toxocariasis from playing in a sandpit which could lead to vision loss?
Sandboxes are giant litter boxes for a passing animal. Humans can become infected by ingesting Toxocara eggs, which can happen easily when a child plays in an infected sandbox and then touches their mouth. Once inside the human body, the eggs hatch and the larvae use our bloodstream as a highway, traveling to our major organs and possibly causing damage. Some infected people experience no symptoms, but others experience devastating ones such as liver or heart failure, or loss of eyesight.
