About Contact Lenses
Maybe you are attracted to the idea of wearing contacts and are looking for information. A lot of people with vision problems prefer contacts because they are more comfortable than glasses and they do not affect their appearance. For many people glasses can be annoying as they can slip down, irritate your nose and ears and cause reflections. Also you need to have a second pair to act as sunglasses or you need to pay more for transition lenses. A contact lens allows you to get rid of this paraphernalia and simply have your vision problems corrected. Most individuals won’t even realize you are wearing a contact lens because they are virtually impossible to see in your eye.
A lot has changed since contacts were first introduced. A hard contact lens was the first lens to be made. These were made of a type of glass and were very rigid and uncomfortable to wear. Most individuals felt glasses were the only way to go because of the uncomfortable material and expense. After all it was very easy to scratch your eye with a hard contact lens when trying to get it out because of the rigidity of the material. These type of lenses were then superseded by polymer based lenses which resulted in greater comfort. However the restricted oxygen flow to the cornea was causing eye sight problems in individuals who wore contacts for several years.
The latest products are silicon hydrogel lenses. These are usually referred to as “soft” lenses. They are made from a plastic like material which allows them to fit the eye much better than earlier lens types. In addition they are very thin and oxygen can pass through them. This does result in them being rather delicate but they are more comfortable than earlier versions. It is an almost weightless material so your eye will barely feel its presence.
With the introduction of the silicon hydrogel contact lens we also have seen the introduction of more color contact lenses. There are a range of colors available, some look natural and some are just for effect. These color contacts can be very effective but there is a downside. They are a bit heavier than normal lenses and they tend to let less oxygen through to the eye. You can also have corrective lenses for conditions like astigmatisms. For people who need to correct both far and nearsightedness bi-focal contact lenses are also available.
The first step in getting contact lenses is to have an eye exam and get your prescription covering the lens type you require (of course you have to take the advice of your eye doctor on this). You should then try out the lenses to make sure that they are comfortable and do not cause any problems. At that point you can think about buying discount contact lenses online. Buying contacts on line is actually much easier than buying eyeglasses online because with glasses there are more issues to consider. Buying contact lenses is easy because you just input your prescription and receive identical lenses but at a lower cost.
