Gosh, they feel great. I’ve been coming to Specsavers more than a month and they cannot adjust the focus of my eyes. My eyes get blurred when I try to watch telly or read my phone. At the shop it seems fine when they adjust it. It’s only when I’m back and in the evening I struggle. But then I struggle the following days. And it gives me excruciating pain in my temples muscles of the head straining to focus.
