A quality pair of sunglasses will protect your eyes from the sun’s harmful glare by blocking 99 to 100 percent of the ultraviolet rays aimed at your eyes (In fact, a cheap pair of sunglasses can work just fine, too, but be sure to check for the sticker). Aside from blocking ultraviolet (UV) radiation, sunglasses can minimize eye fatigue and eyestrain by reducing exposure to bright light. While the UV protection is typically the most important reason to wear sunglasses, many athletes prefer lenses that are tinted a specific color to allow for a competitive advantage in their sport of choice.
Anisometropia is a vision condition in which the refractive power of both eyes is unequal by a difference of of 2 diopters or more). A person affected by anisometropia will usually see a smaller image in one eye and a larger image in another. In many cases, anisometropia is present from birth, which can be difficult (but certainly possible) to detect. Anisometropia can develop at any age, however, and seems to equally affect males and females. An estimated six percent of children between the ages of six and eighteen will suffer from this visual condition.
A breathtaking 68.8 percent of American adults are considered obese. That’s over two-thirds of our nation’s population over the age of 18. Furthermore, three out of every four men are obese. Because of its high rates, and its health risks, obesity is a major concern of health care providers in the United States.
We’re all familiar with that burning feeling you can sometimes get in your eyes. Maybe it’s because you spent the day at the swimming pool, maybe it’s because you got smoke in your eyes from a firepit, or maybe you have been staring at a screen for too long--in fact, if you’re reading this and you’ve been staring at the screen for too long, take a little break before reading on. But, these are explicable and expected reasons your eyes might get irritated. What does it mean when you’re eyes are burning and you cannot think of a reason why?
Ahh, stress. We all have different thoughts that come to mind when we hear the word. The New Oxford American Dictionary defines stress as “a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.” For some people, this stress piles on in high-pressure situations. For others, stress is accumulated over a period of time. You may be aware of the negative effects emotional stress can have on your physical health. But, you probably haven’t given much thought to the effects of stress on your eyes.
