As well as Retinal Photography, at all Norman Prince Opticians practices we now have 3D OCT scanning available. This scans your eye in just a few seconds and gives us a 3D cross-sectional image of the deeper layers of your eyes. This helps us detect the early signs of many eye conditions including Macular Degeneration and Glaucoma.
