After a workout you may notice that your eyes appear red or blood shot. This may occur for a number of reasons but, most commonly, as a result of dry eye or a broken blood vessel in the white of your eye. These conditions do not indicate a serious problem unless you experience sudden vision changes or severe pain.

Glaucoma is an eye disease that can lead to permanent loss of vision if the condition is not treated. Pressure within the eye, called intraocular pressure, increases and can hamper normal drainage of eye fluids. Both of these factors can cause the optic nerve to become damaged.

The colon is a muscular organ located at the end of the digestive tract. The primary function of the colon is the reabsorption of water, minerals and electrolytes, and the elimination of waste. The colon, rectum and anal sphincter muscles control normal bowel movement.

Caffeine does more than just boost energy levels. It can also increase pressure within the eye. This is concerning, because high eye pressure over time can lead to glaucoma, a potentially blinding disease of the optic nerve.

Bleeding can occur in any part of the eye, from the superficial external outer layer, the conjunctiva, to the lining of the back of the eye, the retina. Eye hemorrhages may cause no symptoms at all or cause total vision loss and severe pain, depending on the location.

While contact lenses are designed to enhance your vision, they can also cause problems with your eyes. Dry eyes and irritation are common issues that occur in contact lens wearers, according to the American Optometric Association.

The retina is the tissue that lines the back, inner part of your eye, and the light-sensitive cells of the tissue pass along the information converted to the images you see. Some people have a retinal detachment without a known cause, but in some cases, a detachment may stem from an eye injury or disease.
