This was the first time I'd purchased glasses over the internet, so I checked the SelectSpecs website and all the online reviews. This satisfied me enough to give them a try; I was not disappointed! The online form was simple to complete, and you can also upload a scan/photo of your prescription for their optometrists to double-check. The one bit of additional info they need is the distance between your pupils (for sizing the frames); this can be done easily with a ruler and a mirror (some apps can also do it for you via your phone). The glasses ordered arrived in a sturdy plastic box and black polythene packaging in about 1 week. I bought the cheapest frames, and with the lenses coming with 2 free coatings, the all-in the cost with postage was around £25; absolutely amazing price compared with high-street opticians! The glasses are great, perfect fit and amazingly clear lenses. Would use the site again
