another satisfied Optilabs customer here – like that nice Mr Udder above.
don’t order based on the brochure – the ones I thought would be perfect on paper turned out to look just awful on my face. (some would argue that’s more about my face than the glasses , but I digress..). They have a trial mail order service I think if you can’t get there in person.
I can still defeat the glasses and get eye streaming if I really try hard – but its rare. I use mine every day pretty much and they look great and just work. The photochromic lens is excellent too – really clear and fine for night riding, yet able to shut down for bright days ( a little bright compared to a full mirror lens, but just fine for 99% of the time inc this summer).
If you can get to their showroom take a toddler with you and ask that you use their loos – its behind the workshop and you can have a gander at their trick specs making lathes and stuff. (technical description). very friendly people and independent too.
