Terrible website, awful glasses.
Terrible website, no clear description of glasses or how they work. If you want cheap reading glasses Amazon has a few fixed single prescription options. But if your prescription is above a +6 you will struggle to find ready ad glasses that suit. I got some Occi Chiari glasses +6 that were OK for £15 per pair as I fall asleep and they drop off. So far they're lasting about a year to 18 mths of abuse in bed getting crushed and rolled on.
