Contact lenses are an extremely versatile and popular way of correcting common refractive eye errors, such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. These conditions occur when the light that passes through the eyes isn’t refracted directly onto the retina at the back of the eyes, where it’s turned into messages sent up to the brain. This happens when the cornea – the clear, domed part at the front of the eye - isn’t perfectly shaped, such as when it is too long compared to the focusing power of the eye.

Did you know that babies have to learn how to see? It might seem strange, since using our eyes is something we do automatically all day, but babies need to develop a number of visual skills in order to effectively use their eyes and process what they’re seeing, just like they have to learn how ...

We might get more hours of daylight in the summer, but sunglasses are important in winter too! Harmful UV rays can do just as much damage on a snowy mountainside as on a sandy beach. Our skin might be protected by layers of snow gear in winter, but our eyes are still vulnerable if we aren’t car...

A smoking habit damages every organ and system in the body, including the eyes. We typically think of lung cancer as the main health risk associated with smoking, and then maybe oral health problems next, but the parts of the body that have direct contact with the smoke aren’t the only ones hur...

One of the many things diabetes can impact when it isn’t carefully controlled is eyesight. Whether it’s type 1, type 2, or gestational diabetes (which functions like type 2 while it lasts), the risk of developing a variety of eye diseases (including cataracts, diabetic macular edema, diabetic...

Human eye color comes from melanin, the same compound that determines skin and hair color. Melanin absorbs light, even some UV light, which is important for the iris — the part of the eye that controls how much light enters the pupil. Melanin and Pigment Types There are two different types of m...

Human eyes are incredibly complex, which means there are many ways something can go wrong. The particular one we want to focus on is retinal detachment: a serious, sight-threatening condition that will affect 1 in every 300 people at some point in their lives. Retinal detachment can be treated wi...

If you have poor vision caused by nearsightedness, farsightedness, or astigmatism, but you are frustrated by the limitations posed by wearing prescription eyewear, then you may be considering laser vision correction. More specifically, you may be considering LASIK.

Since as early as 60 A.D., people have been using vision-correcting tools to help them see. Around that time, the Roman philosopher Seneca used a glass globe of water to magnify text, while Emperor Nero needed a magnifying emerald to see gladiator fights. Thanks to millennia of innovations since ...

Vision problems can’t all be corrected with glasses or contact lenses. When even the strongest corrective lenses aren’t enough to produce clear vision, that’s visual impairment. Even for those of us who don’t live with visual impairments of our own, it’s good to understand them so that ...
