Good advise from Zooma, I got mine done at the same time as my reading glasses,it's a slightly weaker prescription,so that the target doesn't look too fuzzy,also took my pistol,the optician said he really enjoyed doing it,as it was a break from the normal stuff they do,he also took a lot of care correcting a slight astigmatism as he thought it may effect alignment of the sights,all for £25 Specsavers,Kingston.....highly recommended
