I have had around 3 pairs of glasses via direct sight now (i constantly loose them) for £20 a time i'm very happy. I have been wearing glasses since i was 6 these glasses are far Superior to the boots glasses i had as a child they were a nightmare and by far the worse glasses i have ever owned. I wear my glasses all the time (hence having several pairs as i miss place them, order a new pair then the originals turn up) They are of the same quality as my converse glasses (in fact all have anti scratch on the lenses including my converse, the converse have scratched and the direct sight ones are still perfect) I've recommended direct sight to various people who have all been happy with the budget glasses.
