Important InformationWe encourage arriving 10 minutes prior to your appointment time to ensure we can understand all of your vision needs.

We all know how powerful the sense of sight is - but when we think of body health, we often don’t think about what our eyes need.

An AR coating will help to prevent sunlight from reflecting into your eyes when the sun is behind you. This can help if you tend to experience those annoying reflections or ‘ghost’ images when wearing sunglasses.

Very useful to get a good reading of the power of your lasers. I’ve read a bit over 4000 mW on my most powerful laser so I’ve no idea how it works with the most powerful lasers of 5/6/7W and more. Seems to have problems reading powers under 10 mW Battery seems to last quite a lot of time too. Probably not the most precise but at this price there’s nothing to really complain about.
