With the increasing use of the prescription glasses, different frame designs of prescription glasses have become available. Prescription glasses are divided into three different kinds – full rimmed, semi rimmed and rimless. The most popular and used design are the full rimmed prescription glasses. These full rimmed glasses have a rim around the lenses which offers protection against falls or shocks, but it also increases the weight of the pair. Semi rimless glasses on the other hand offer the advantages of both full rimmed and rimless glasses, all the while radiating a dynamic appeal. Though the protection offered by the semi rimless glasses are lower than the full rimmed, the reduction in weight make up for it. Rimless prescription glasses are the most expensive of the prescription glasses as well as the lightest and most comfortable.
As the prices of the semi rimless and rimless glasses are more than the full rimmed ones, proper care must be taken to check the fitting of the pairs. An incorrect fitting will render the prescription glasses uncomfortable and will lead to the wastage of your money. Follow the steps mentioned below to ensure a better fitting.
Obtain a copy of your prescription from your eye care provider. Your eye doctor is required by law to provide you with a copy of your glasses prescription. Many retail eyeglass stores have on-site optometrists as well. Decide the type of rimless frames you would like to wear. Metal frames are available in both formal and casual styles. Try on several different types to find the look you want. Select the right shape. Ideally a frame should be a different shape than your face shape. A good guideline is to pick a rounder frame if you have square or angular features and look for a square-shaped frame if your face is round. Look for smaller frames if you have a strong prescription.
Your glasses prescription will have numbers in the sphere category that indicate the strength of power in your lenses. A number above 2.00 to 3.00 indicates a stronger power. Don't try to fit rimless frames for prescriptions that are over 6.00. The edges of the lenses become too thick for nearsighted prescriptions (written as -6.00 or higher) and too thin for farsighted prescriptions (written as +6.00). There are certain exceptions, depending on other factors in your prescription, so if you are unsure, check with your eye care practitioner.
