Many people who are trying out contact lenses for the first time will have a lot of questions in their mind. They will not know how to wear the lenses, how the prescription has to be read etc. They may not know if the lenses can be interchanged between the eyes. Following these simple tips regarding contact lenses can clear many such doubts.

An eye doctor or an ophthalmologist should be consulted first. He will conduct a proper test for the eyes and determine the power of the spectacles or contact lenses that should be worn. In certain states, contact lens maker can also be consulted if the contact lenses are only required for cosmetic purposes like changing the color of the eye. People who want contact lenses only for cosmetic purposes do not normally wear spectacles for reading and other work. Contact lenses are objects that need to be fit into the eye in the right manner. An ophthalmologist or eye doctors are the best people to assist you in this regard. In countries like the United States of America, using a prescription that is valid from an eye doctor can legally purchase a set of contact lenses. But the doctor will first check if your eyes are suitable enough for contact lenses to be worn in them. Only then will he prepare a prescription for contact lenses that should be worn by you. Contact lenses are not recommended for certain people.

On first sight, a prescription for contact lenses might look like some kind of coded message. But, in reality, it is very simple to decode and understand what is written in this prescription. It will state exactly to what power your contact lenses should be made. These contact lenses will have to be replaced on a regular basis. Some lenses will have to be replaced every month or every two months and some lenses will have to be changed everyday. The replacement of contact lenses is done mainly on the advise of the doctor. Some brands of contact lenses are such that they have to be replaced regularly. But the eye doctor is the best person who can decide how often the contact lenses should be changed depending upon the condition of your eyes and your lifestyle.

The biggest question that comes next is how the contact lenses should be applied onto the eyes. Normally contact lenses are in the shape of a taco. Some people even say that they look like a small soup bowl. But many people are not able to make out the right side and the wrong side of the contact lenses. The best way to determine this is to hold the contact lens on your finger so that it stands like a cup. Then you should look carefully at the sides of the cup. The contact lens should stand in the shape of a ‘U’ and the top part should flare out in the shape of a fan. This indicates that the contact lenses are in the right position and they can be worn in this manner.

Many types of contact lenses have a mark on them, which has been made by laser, and this also shows the name of the manufacturer. This mark will also give you an indication if the lens is being held inside out. There is no need to worry if the contact lenses are worn inside out. They might cause a little bit of discomfort but they will not do any harm to the eye.
