But before you try to buy the products, you need to understand the contact lenses base curve. You would see that there are some numbers on your prescription. Therefore, you should try to base on these numbers to select the most appropriate type of contact lenses for yourself. If you ignore this, you will usually find that there would be great trouble.

In the first column of the prescription, you would usually find the abbreviation indicating left or right eye. O.D. refers to your right eye while O.S. refers to your left eye. Of course, some of the prescriptions would use RE to stand for right eye and LE for the left one. This is important if you really want to find the contact lenses base curve.

Then, you can move to the column next to it and you will see that there would be indication about the power of your eyes. The number would usually be between + and – 20.0. The power would be a little bit different from the one when you wear the normal glasses. It is because the contact lenses would be closer to your eyes so the power would be changed a bit.

After that, it comes to the way for finding contact lenses base curve.

The column showing B.C. means the base curve. It refers to the curve measurement of your lenses. Some of the brands in the market would try to offer a fixed size of base curve, while some of the brands would provide the base curve for several sizes. Usually, you would find that the contact lenses base curve number would range from 8 to 10 in the prescription.

After that, you can find the diameter of the lenses. You would then be able to make a comparison between the products and find the lenses which can be worn by you in a comfortable way.

To conclude:

• Contact lenses base curve would be meaningful to you only when you understand the information of other things, like the left or the right eyes, on the prescription. Therefore, you should always try your best to ensure that you can understand all the things on the prescription, and you can compare the contact lenses base curve of your prescription and the information provided by the sellers regarding your target products of contact lenses. If you do not pay attention to this, you will find that there is a difficulty for you to get the appropriate product of contact lenses. Therefore, you should always work hard to search for the information from the sellers and match them with the information you have in the prescription.
