Product description
The Sloan board uses traditional optotypes that follow a 5×5 grid idea. The Sloan vision test uses a logarithmic format and has equivalents on each side. They include LogMar, decimals, 10 feet and meters for easy visual acuity recording. Two smaller groups from 5M to 2M for repeated tests (20/25, 6/7.5 to 20/10, 6/3 equivalents).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
