Intermediate Visual acuity (IVA) assessment

Intermediate visual acuity (IVA) will be assessed with the Intermediate Visual acuity chart which is similar to the prevalent Jaeger chart. It consists of short blocks of text in various type sizes.The computer screen is set at a specific reading distance (1 meter) and the patient is asked to read the passage with the smallest type he/she can see. According to the smallest text he/she can read, IVA is classified from IVA1 (which is considered the equivalent of 20/20 distance visual acuity) to IVA5
