theres: Soft Toric Lenses - Toric lenses have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There's also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around. To provide crisp vision, toric contact lenses cannot rotate on your eye RPG(rigid gas permeable) Lenses - Unlike hard plastic lenses, RGP lenses are gas permeable. That is, they allow oxygen to pass through to the cornea. They are less expensive and more durable than soft contact lenses, and provide wearers with clearer, sharper vision. Unlike soft contact lenses, RGP lenses have a low water content and therefore, resist protein deposits and bacteria. Because they are rigid, they hold their shape when the wearer blinks, allowing for crisper vision. Other benefits include ease of handling and ease of care. Because they do not contain water, proteins from the eye do not build up on the lens, so the lens stays cleaner, and requires less maintenance. RGP's are not for every patient. Because of their rigid form, they require more break in time for the patient to become comfortable with wearing the lenses. Also, if you discontinue wearing your RGP lenses for a few days, it may be difficult to become used to wearing them again. RGP's differ from soft contacts in that becoming comfortable with wearing a rigid lens requires the patient to wear their lenses all the time. Soft contact lens users may discontinue wearing their lenses for a few days, and immediately be comfortable with having them inserted again.
No, not really. Astigmatism simply means your eye is shaped more like a football than a baseball, and can be corrected with glasses. Eye pressure is the inflation pressure of the eyeball, like measuring the pressure of your tires. The eye pressure may be slighty off if measured on a patient VERY high astigmatism, but only by about one point, which is basically not significant. We usually don't pay attention to the astigmatism when measuring eye pressure.
If you put them in wrong, can cut like a paper cut if you really really do it wrong.
i think its because, people that wear contacts to sleep isn't comfortable with them in. Plus your eyes need air coming threw although you sleep in them less air comes threw. Its really uncomfortable for your eyes that's what makes it hard for you too sleep.
There is no telling if one or the other of you may share some kind of germs between each other. Do you really want to share contact lenses and take the chance on going blind?
wear glasses or some people are born with the ability to see things really close up.
Are you referring to astigmatism, which is an eye condition in which the lens of the eye is malformed (not perfectly spherical) and makes the person afflicted often feel as though they see the world as though its under water...
It may be possible that your astigmatism is not very severe, so that you are unconsciously compensating for it, with eyestrain and headache as a result. Sounds like something worth following up on, since you may need just a pair of glasses rather than something invasive or pharmaceutical. Here's an article on it: http://www.kellogg.umich.edu/patientcare/conditions/astigmatism.html Also, "blurry" is a very subjective evaluation for people to make. Some people think they see just fine when they have 20/80 vision and really should be wearing glasses all the time. Other people with a very slight eyeglass prescription think they see horrible and are surprised when the eye doctor doesn't prescribe glasses for them.
Really! Why does this happen? (Btw actual question)

No its not. It just depends on the color you get I guess. I don't really know whats wrong about men wearing colored contacts.

Yes! In the video, "You Belong With Me," Taylor was really wearing her real glasses. So, she does wear contacts.
