A lenticular is a printed image that shows depth and motion as your viewing angle changes. We use lenticular images in this chart to illustrate how structures change from a normal to a diseased state. This chart shows one large normal eye at the top. The lenticular images showcase eight common eye disorders: glaucoma; conjunctivitis; corneal ulcers; macular degeneration; cataract; diabetic retinopathy; blepharitis; and retinal tear and detachment. Size: 21 inches x 29 inches, in 3D plastic, with a hole at the top for easy hanging.
