How to Read Your Eyeglass Prescription Your prescription generally has three numbers. For example, it could read -5.00 -1.50 x 180. The first number indicates the power of the lens required to correct your nearsightedness or farsightedness. If this number is negative, you are nearsighted, or you have difficulty seeing distant objects. A positive number indicates you’re farsighted, or you have difficulty seeing close objects. The higher this first number is, the stronger your glasses will need to be. The second number is a measure of your astigmatism, an uneven or oval shape of the front surface of your eye that results in blurred vision. Many people who are nearsighted or farsighted have some astigmatism. The third number, ranging from 0 to 180 degrees, represents the axis or direction of your astigmatism. If you have further questions about your prescription, speak to your doctor. #ttd_eye#ttdeyeofficial#ttd#purchase#ordering#tips#tipsmakeup#contactlensestips#eyehealth#eyeprotection#eyedoctor#lensescase#contacts#makeup#faceart#eyelook#contactlenses#eyeglasses#eyecontact
