Colour blindness refers to an inability to distinguish between some of the colours that others can perceive as different. It is often the result of a genetic deficiency, but can also result from eye, nerve, or brain damage, or exposure to particular chemicals.
As is briefly explained in How the Eye Works, the retina contains primarily two types of cells – rods and cones. Cones are responsible for colour perception. There are three types of cones, and each is sensitive to different wavelengths. The receptors are often referred to as – green, red, and blue,- though this distinction is not entirely accurate.
Keeping your eyes healthy is about more than just vision. Regardless of whether you sport glasses, contact lenses, or have no need for either, dark, puffy eyes signify aging, stress and sleep deprivation. Taking care of your eyes with an eye cream will help ensure that your eyes are bright, no matter what hours you’ve been keeping.
That being said, navigating the eye cream market can be a daunting task. To help you out, we’ve compiled a bit of information to introduce you to the world of eye cream.
Eye colour is determined by multiple genes, though the actual number of genes involved remains unknown.
The most simplistic explanation of eye colour inheritance, using just blue and brown eyes, is as follows. You have one eye colour gene from each parent. If either or both of these genes are “brown,” you will have brown eyes. If neither is “brown,” you will have blue eyes. Remember, each of your parents has two genes from their parents as well, so it is possible for two brown-eyed parents to have a blue-eyed child. How? If each of the parents has a recessive “blue” gene that they transfer to their child. However, if both parents have blue eyes, it is impossible for them to have a brown-eyed child, as neither of them has a dominant “brown” gene.
Sports can be great for the body and wreak havoc on the eyes. Regardless of whether you’re playing contact sports or going for a sunny jog in the park, it is important to be prepared for whatever hazards your eyes might encounter.
Whether throwing on a coat of mascara and under-eye concealer for work, or glitzing it up with a dramatic smoky-eye for a night out, eye makeup is a part of everyday life for most women.
In order to keep your eyes healthy, however, while enjoying all the benefits of eye makeup, it is important to keep a few tips in mind.
