Balsam Alabdulkader – Leat Reading Chart (BAL Chart) – Chart 1

The BAL chart is the first, standardized continuous text near visual acuity chart in Arabic. It was designed based on the accepted design criteria for reading acuity charts


The BAL charts allow the assessment of:
1. Maximum reading speed (the fastest reading that a person can attain using large print),
2. Critical print size (the smallest print that allows maximum, or near maximum, reading speed) and
3. Reading acuity (the smallest print that can be read). The charts can be used to measure near visual acuity for patients of all ages, determine near reading additions for presbyopes, predict performance with magnification devices, determine magnification, and measure performance with low vision devices.
