These days you can order anything online even prescription spectacles. 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.
Choose a legitimate seller
There are many online eyewear shops. The wise thing to do is order your spectacles from a reputable online store that has a lot of positive reviews and few negative posts. You also need to check the reliability of the online shop from the websites of consumer protection agencies. Making sure that you get a reliable seller is just the first step.
Get your 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. In case you do not have a current prescription (that was issued less than a year ago) then you need to see your optometrist to get one. The prescription needs to include your pupillary distance (distance between your pupils). This pupillary distance is a key measurement since this is what the online optician will use when placing the center of the lens. This measurement increases the accuracy of online spectacle orders.
Find out the return policy on the spectacles
Not every prescription glasses are equal and not all of them are a good fit for you. In case the glasses are not a good fit, you need to know whether you can return them and get others. You need to know after how long you can return the spectacles. The longer the time-frame to return the glasses the better. Make sure that the store that you order from has a return policy whose terms you are comfortable with.
Apart from the return policy you need to find out if the company offers some form of warranty on their products. You need to know the terms of the warranty since the glasses can sustain scratches and even cracks. 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).
Special perks offered by the company
Some online eyewear companies offer various benefits when you buy from them. Some companies allow you to order multiple frames then choose which one they like after trying them for some days. Other online eyewear companies also offer anti-scratch and anti-glare coatings with each order.
Some online opticians offer free shipping for orders above a certain amount. There are other companies that specialize in non-prescription spectacles as well as prescription spectacles. These companies are a good choice if you suffer from computer screen strain and just want great non-prescription glasses.
