Things To Consider When Choosing Prescription Glasses Online
Technology has caught up with the eyewear industry and you can order eye ware online. This has led to the emergence of various known and reliable brands as well as a whole list of scammers just like any Internet-based industry.
Opt for a recognized seller.
The Internet is littered with online eyewear shops. Choose a seller that has many  positive reviews compared to negative ones.  You can also check the rating of the supplier on the websites of consumer protection agencies that vet online eyewear companies. Making sure that you get a reliable seller is just the first step.
Have a current prescription
Purchasing prescription glasses online still follows some of the protocols done in a physical store. You need to get a current prescription before you begin ordering for your glasses. If you do not have a current prescription (that has been issued over the last 12 months) then you need to visit your optometrist. You also need to make sure that the distance between your pupils (pupillary distance) is measured. This pupillary distance is a key measurement since this is what the online optician will use when placing the center of the lens. This is integral for online ordering because retailers want to make sure the lens measurements are accurate.
Find out about their return policy
All prescription sunglasses are not the same and different people like different kinds of glasses. You need to find out the conditions of the return policy just in case you get glasses that do not fit. You need to find out within what number of days can you return the spectacles. The longer the duration of return the better. Apart from just knowing if the company has a return policy you need to know what the terms are.
You also need to make sure that the website offers a warranty on their products. You need to know if the spectacles have a warranty so that in the event that your lenses are scratched or get some cracks you can get a new pair. When looking at the warranty assess the terms of a refund and whether you get the whole amount refunded (plus or minus the shipping cost).   Get more facts about glasses at https://en.wikipedia.org/wiki/Glasses.
Special offers given by eye-wear sellers
Some online eyewear companies include some special offers to their clients. Some of these companies allow you to order multiple frames, try each of them before settling on one frame then return the rest. There are other companies that include anti-glare and anti-scratch features in all their spectacles.
Some online opticians offer free shipping for orders above a certain amount. Some online eye ear companies specialize in both prescription and non-prescription glasses. These companies are a good choice if you suffer from computer screen strain and just want great non-prescription glasses.
