This is a floral-themed diagram which one can use to gently exercise the eye muscles. Alternatively, one can use it as a focal point for meditation. Inspired by the "Tibetan eye charts" which have circulated for many years. I found them to be a bit harsh and linear so I designed my own more gentle nature-y version.
 
This is a digital download ZIP, consisting of 2 .pdf files. One is the eye chart itself and the other is the instruction page.
 
This will print nicely in both color and black&white.
