Glasses sold at the online shops are always called the internet eyeglasses. Most online eyewear providers feature a catalog that shows the frames they offer in detail. You can view each available color and read descriptions on the features, such as what material the frame are made of and whether they have spring hinges. You can sit at the computer to search from one to another. Generally, you can be recommended several styles in the local shops. But you have to decide by yourselves completely at the online shops, which seems to be overwhelming.
Also, you need to decide the materials of lenses and lens coatings. Are polycarbonate, high-index or regular plastic lenses best for you? Do you need ultraviolet (UV) coating? What about an anti-reflective coating? Is a tint a good idea? If you have no problem in making these decisions by yourself, internet glasses are just OK!
Concerning the prescriptions, most online optical providers present you with several ways to go about this important task. Some suggest the simplest method, which is to have your prescribing eye doctor or an optician take the measurement for you. Alternatively, they offer step-by-step explanations of how to take your own PD in the mirror, or how to have a friend take it for you. Basically, there is no problem to worry about any more.
Internet glasses are supplied at reasonable prices, and the latest designs can absolutely attract your attention. If you get a chance, why not try?
