Of course, you can use your own Test Lenses to accurately measure your own refractive state, to 0.25 diopters. This works accurately in engineering-ecience. Thanks for your review.

Dear Dr. Guyton, Very interesting - thank you! I had never seen this detail before. I measure a positive state for my normal eyes, by using a Snellen and a plus lens. At 20/20, clear vision. Then I use a plus lens, until I achive "just blur", on the 20/20 line. My refractive state is therefore, +0.5 Diopters, spherical. This assures me that my 20/20 is very solid.

Getting rid of accommodation in this measurement, is extremely difficult. I always use test lenses on my eyes for accurate objective measurements of my refraction state.

Why do Optometrists use minus cylinder, rather than plus cylinder?

Aren't you supposed to start in the + Direction by starting with + fears to fog the patient and relax his accommodation?
