All you'll need to know about your ophthalmic Prescription in order to buy glasses online
Before you sit down to have a look it's probably best if you have your most recent optical prescription to hand (this should have been given to you by your optician and is valid for a maximum of two years). Your prescription should have your pupillary distance measurement in millimetres to ensure that your lenses can be made to perfectly suit your eyes.
Next, make sure that you have a bright and clean digital photograph of your face taken while you are looking squarely at the camera with a smile or a neutral expression. Some sites offer Live Try On facilities and these will usually take your photograph for you.
Go to a suitable website that allows you to Try on & Buy glasses online and click on the "Try On" button beside any frames of interest. Next, upload your photograph or else click on the webcam icon. If you opt for the webcam option, a dialogue box will appear asking if the Try On software can interface with your webcam. You should click "Allow" when this happens. The glasses frame of interest will now appear in front of your face. Some versions of Virtual Try on will allow you to snap up to six pictures of your face wearing different frames so that you can try on up to six pairs of glasses and then quickly scroll through the Try on photographs. This allows you to narrow your search and find the pair(s) that are perfect for you.
If you are tempted to buy then you should click to purchase. Many sites then present the customer with the dimensions of the frames of interest in millimetres. These should be checked against the measurements of your own frames. Thus you eliminate the risk of purchasing frames without adequate bridge width for your nose or temple length to sit comfortably behind the ear etc. As a rule of thumb you should opt for frames of similar dimensions to your existing comfy pair.
Next you need to enter your prescription details into the form dedicated for that purpose.
Remember: Don't check once, check twice and check thrice that
