What are contacts made out of?
These are the types of contact lenses and the material(s) they're made out of: 1. rigid lenses - polymethyl methacrylate (now improved) 2. soft lenses - silicon hydrogel (which is the material that is being used in manufacture of contact lenses today) 3. hybrid - mixture of materials of both rigid and soft lenses
Why do my contact lenses tear I am wearing month to month contactlenses but they keep on tearing and do not even hold for a week then they are taered or chipped?
You probably have soft contact lenses. They are very thin and can easily be ripped you will have to be more gentle with them. I have contacts that have to be changed every other month and they are soft contacts but i am gentle with them so they never rip. If you have hard contacts then they are probably low quality.
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.
Why are soft contacts no good for astigmatism?
Soft lenses cannot correct astigmatism because it only has a sphere lens. For a lens to correct astigmatism it must have both sphere and cylinder lenses. Cylindrical lenses are used to correct the power of the astigmatism at a certain axis, spheres are only capable of correcting power. But it's not exactly true that soft lenses are no good for astigmatism. They are, we call them Toric contact lenses.
What happens if you cry while your contacts are in?
People do it all the time, just be aware of possible movement of the lens because of all the extra lubrication by the tears, is is possible that one may pop out. Dont fuss, just put it back in.
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.
Should I wear glasses or contact lenses?
This depends on how bad your vision is, if it is not super bad you can probably wear contact lenses rather than glasses. Also some people have dry or easily irratible eyes and therefore have a big problem with thier contacts. Finally make sure to check with your opthamologist about anything else that might be paticular to you. Hard contact lenses are typically more expensive than soft contact lenses because they are not disposable. Hard lenses are designed to be cleaned and reused and often last for more than a year. Hard lenses are typically reserved for special eye problems were soft lenses are not practical.
Can i wear my contact lenses multiple times?
Yes. There are contacts that you can wear for 6 months as long as you take care of them, there are also soft contacts that are called daily disposables that you can throw away after wearing them for 1 day.
You are 16 and both your eyes are around 700 near sight First of all for anyone who's been wearing RGP has it been helpful in terms of slowing your near sight down Would you recommend it for a teen?
I have never heard of any contacts of any type slowing down nearsightedness (myopia). RGP lenses unlike soft-lenses, take some getting used to as they are more rigid, but once they are gotten used to they do offer some advantages over soft lens contacts. Having been a very nearsighted teen at one time, I would highly recommend contacts as teens tend to make inappropriate comments to other teens with extremely thick lenses in their glasses. Contacts in almost all cases are used for cosmetic, not medical reasons.
What are eye contacts?
Eye contacts used to be plastic. They were very hard and uncomfortable too. But now though they are still made out of plastic. They use different types of materials that incorporate water. The water allows them to be soft and flexible. Also more oxygen can get to the cornea. Now a days both "soft" contact lenses (those that incorporate water) and "hard" contact lenses (those made out of hard plastic) can be bought. For a really basic answer. Eye contacts are plastic lenses that you put on the pupil of your eye. They do the exact same thing as glasses do, make you see farther or make you see nearer (or both!).
What are disadvantages of purchasing cheap contact lenses without prescriptions?
Advantages: * Glasses get annoying because you can't use your peripheral vision but with contacts you can see everywhere * You don't have to worry about your vision being obscured by dirty glasses * If you play sports contacts are much safer because glasses can break and injure your eyes * With contacts it's much less of a hassle doing daily activities because you don't have to worry about your glasses Disadvantages: * When you get tired your eyes start to feel really dry and they make you more tired * If you don't clean your contacts properly you can develop eye problems * It's sometimes annoying to have to bring around your contact case and liquid when you're not going to be coming home for the night Hope that helps =) As a side note, hard contact lenses are healthier for your eyes because they are smaller and allow your eye to get more oxygen but are more of a hassle in the beginning because they take a few months to get used to and are very irritating at first. They are not good for sports. Otherwise soft lenses are the way to go.
