The Sheridan-Gardiner Test contains both near vision and distance vision tests according to the Faculty of Ophthalmologists and Snellen Standards. This Test also includes a reduced Snellen Test. Testing depends on matching shapes rather than identifying or naming letters. All are reversible. The Sheridan Gardiner Test is primarily designed for children but is also usable for deaf mute or other patients unable to interact with traditional letter based visual acuity tests. Results are more reliable than illiterate E or similar tests. A series of orthoptic booklets in washable plastic finish are included with the basic kit to augment the range of letters in each size.

These are sometimes referred to as the Cambridge Crowding Cards.
