Everything You Should Know About Buying Eyeglasses Online.

It is possible to buy eyeglasses online but the thing is that you may not be able to recall what the doctor prescribed and even if you have the prescription it might not be nearby.Ideally, the standard prescription is only good for about 2 years and then you have to get another eye check-up for the ophthalmologist to decide on the way to go. You can get your optician to do another prescription but you do not have to limit your choices to what is available online. You will definitely walk out of the clinic with a prescription for the eyeglasses whether you ask for it or not. This is the prescription that will alert you about the eyeglasses you ought to purchase. Even so, make sure you do not do a blind order based on the clinical term written on the pad. You should be aware of your pupillary distance measurements which is commonly referred to as the PD. The figure can be found on the prescription but at times it is not available. You can check out this website on how to do a PD measurement at home or just call your eye doctor for this info. If you want to buy distance glasses the standard PD is 60 while 57 is for reading glasses.

You have to specify the frame when you are making the order. Generally, frames are made based on the size of your temple, bridge and eyes. These measurements are engraved on the inside temple and if you are happy with the fit of the eyeglasses you own you can use those. If that does not cut it you will have to try different kinds of eyeglasses at your local optical shop so that you can determine what works for you. In such a manner, you will not have a problem choosing the frame measurements when placing your order. Your face shape will also dictate the kind of eyeglasses you should buy. The main types of faces are triangular, square, round, oval, oblong and diamond. You can work with your doctor in determining your face shape and the eyeglasses which will be best for you. Since there are no complex examination required for this exercise you can fit the activity on your eye appointment so that you will be aware of what you should buy in the end.

The type of the lens you should buy is something else you have to think about prior to the purchase. Your eyeglasses can either have tinted lenses, clear or photochromatic. You cannot benefit from the eyeglasses if they do not come with lenses too. The strength of the lenses is proportional to the thickness.
