Correcting Astigmatism with Contact Lenses
Astigmatism for a long time was an eye problem that could not be fully corrected with contact lenses. Mild astigmatism could be adequately improved with soft contact lenses, but there weren't options for more severe cases. The eye problem itself results from a misshaped cornea - rather than being spherical like a ball, the cornea in people with astigmatism is oblong, shaped more like a football. Because of this shape, light rays can't refract properly against the retina. Instead of focusing the rays on one spot, the odd shape causes light to refract in multiple locations on the retina, causing the blurred vision, regardless of distance, that is symptomatic of astigmatism.

Gas Permeable Contact Lenses
Gas permeable contact lenses offer the best of both worlds. Rigid but less so than traditional hard contact lenses, gas permeable contact lenses are extremely comfortable. And because they're more rigid, they are better at correcting vision than soft contact lenses. It all has to do with the structure of the polymers used to make these lenses. The oxygen-permeable materials are better able to hold onto the lens shape and better shape means that vision is crisper and clearer.

Prosthetic Contact Lenses
When you look at someone, one of the first things you notice is the other person's eyes. What you may not notice is that sometimes, those eyes that peer back are covered with prosthetic contact lenses. Prosthesis is any artificially-created device that's been created to replace a body part. Most often it's the prosthetic limbs that grab the media attention, but prosthesis can be created for various body parts including heart valves, teeth and even the eyes.

The Different Types of Contact Lenses
The types of contact lenses available today are nearly as numerous as the corrective issues they're designed to correct. But today's contact lenses don't even need to be corrective in nature. Many are purely aesthetic, enabling a wearer to change eye color from brown to violet, for example, or to change from the appearance of human eyes into eyes that resemble that of a cat or wolf or even an alien!

Bifocal Contact Lenses
Nature intended for us to see both near and far, but for some reason nature also decided that as people aged, these vision-enhancing abilities would begin to diminish. The condition in which the lens in the eye becomes less flexible with age is called presbyopia and it causes a diminishing ability to see objects up close. Fortunately bifocal contact lenses can help correct what nature has taken away.

Contact Lens Maintenance
Many people don't realize how important proper contact lens maintenance really is. When you think about it, wearing contact lenses isn't natural. What you're actually doing is willingly placing foreign objects into your eyes which are some of the most sensitive parts of the body. You wouldn't normally allow something unsanitary into your body, yet people place dirty contact lenses into their eyes all the time!

Color Deficiency
Understanding and Living With Color Deficiency
A color deficiency is what most people mistakenly refer to as color blindness. Labeling an individual as color blind is inaccurate because overall a person's eyes function properly. The individual is able to detect, focus on and process images. Except for the condition called monochromacy, an affected person is not blind to color.
