Sloan Eye Chart
Sloan letters, designed by Louise Sloan in 1959, are a set of optotypes used to test visual acuity.
This set of optotypes consists of ten specially formed "letters", C, D, H, K, N, O, R, S, V and Z. These letters, unlike the ones used in older Snellen charts, are designed to give acuity testing results that are comparable to tests made using the Snellen Eye Chart.Subsequent rows have increasing numbers of letters that decrease in size. A person taking the test covers one eye from 6 metres or 20 feet away, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that specific eye.
The major differences between the Snellen and Sloan eye charts lie in the optotypes themselves. Snellen optotypes use bold, larger lettering with serifs—the smaller strokes attached to the ends of a letter symbol. Sloan optotypes don't utilize serifs; rather, they use a more modern design and font.

Please see our "Details" section for more information on the construction, and care of our table trays. In the potichomania process, the glass acts as both a foundation and protective finish, saving the step of varnishing. The original intent was to recreate Greek and Etruscan vases by simulating rare and expensive Sevrés porcelain.

Details & Care of Tray
This tray measures approximately 8x8 inches. The relative thinness of the tray – just over 1/8” thick – belies the complexity of the potichomania process. Each of our trays is comprised of a glass tray, three layers of 28# paper, four coatings of varnish, and finished with two coats, each of paint and clear acrylic spray. We’ve added a high-quality felt pad on the bottom in order to protect your home surfaces.a
Care: Please spray with a gentle glass cleanser and wipe clean. Do not submerge in water. For decorative purposes only.
