Continuous E

Continuous E“ typically refers to a standard optotype used in vision testing, specifically in eye charts. It consists of the letter ”E“ oriented in different directions (up, down, left, right) to test visual acuity. The patient is asked to identify the direction the ”E" is pointing. This type of visual acuity chart is especially useful for non-verbal patients or those who cannot read letters, such as young children or people with language barriers.
