NEAR visual acuity testing

Visual acuity test charts are dynamically prepared based on a users choice of settings

• Test distances from 0.33 to 6 meters (14 inches to 20 feet)
Enhanced logic for resolution dependence of smallest optotypes at closest test distances

• Gesture driven:
- larger - smaller optotypes (swipe up and down)
- randomization (double tap)
- selection of highlighted letter / line
- One touch, pop-up magnifier. Helps test administrators verify small letters
