I would make an appointment with your eye doctor to have him/her check to see what the problem is. That doesn't sound like it is going to be good for your eyes.

What are gas permeable contact lenses?
GP contacts are made of a firm, durable plastic that transmits oxygen. GP contact lenses clean and disinfect easily, don't dehydrate, are easier to handle, and last longer than soft lenses.
How did the market for contact lenses grow in the 1990s?
about 30 million people in the United States wore contact lenses, creating a $2.5 billion market. The largest market was for soft lenses, with 27.6 million wearers. Rigid gas permeable lenses accounted for 5.6 million wearers.
How can I have my astigmatism corrected?
Contact lenses for correction of astigmatism are generally either gas permeable lenses, which are semi-hard lenses, or toric soft contacts. There is also a type called Orthokeratology lenses which are worn at night to help reshape the eye. Your Opthamologist will know they best type of you or if contacts are even the right way to go.
What are the different types of contact lenses?
Contact lenses may be daily or monthly.Daily disposables are worn once and thrown out. They are convenient and hastle free and do not require any lens care regimes.Monthly disposable lenses are worn for a month and require cleaning every time they are used.Depending on your need and frequency of use either option could be suitable for you.Contact lenses basically are of two types soft and hard – These are made of plastics and other material that allow oxygen to pass through to the cornea. The hard lenses most commonly used today are rigid, gas-permeable lenses for short. Excellent
What are rigid gas permeable contact lenses?
made of plastic that holds its shape but allows the passage of some oxygen into the eye. Some believe that RGP lenses may halt or slow the progression of myopia because they maintain a constant, gentle pressure that flattens the cornea
Is flannel permeable?
Flannel is a loose woven material that is soft. It is permeable to gas and liquids.
Why was contact lenses invented?
In 1948, California optician Kevin Tuohy (1919-1968) introduced the first contact lenses that resembled modern gas permeable contact lenses of today. Wichterle and Lim's discovery led to the 1971 launch of the first FDA-approved soft contact lenses in the United States - Bausch & Lomb's "SofLens" brand contacts. It was done for people who didnt like to wear glasses..

What are the best contacts if your eyes are getting really dry and blurry and you have astigmatism?
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.
