Illiterate “E” Wall Chart
This sight testing chart conforms to the Snellen notation for 6, 4 and 3 metres. It can be used directly or indirectly (i.e. using a mirror).
The illiterate “E” also known as the “tumbling E” for testing visual acuity of people who are illiterate, handicapped or where English is not their first language or for persons who cannot speak.
It can be used in conjunction with a card with an E marked on it that the patient holds and rotates to indicate the direction the fingers of the E are pointing.
Alternatively, the fingers of the hand can be used to indicate the direction the E fingers are pointing to.
Each line is numbered for easy referral.
