Please download EYE HANDBOOK from iOS App Store or Google Play Store.
Once installed, click on 'Continue without login'. Perform the pre-assessment tests with the screen set on the brightest tolerated lighting. Begin with the right eye. Cover the left eye with a patch/palm (do not apply direct pressure on the left lid or eyeball, to prevent blurring of vision). Wear prescription glasses if available. Keep the screen 14 inches away. Stay in a well-lit room. After completing the test on the right eye, transfer the cover, and test the left eye.
EYE HANDBOOK --> TESTING
(1) VISION TEST --> NEAR VISION TEST --> ALPHABETS
There are 7 charts. Begin with chart 1/7. Read the lines, swipe left to reach the smallest readable line. Take note of the chart number. Take a screen shot and label right or left.
(2) AMSLER GRID
Chose the white background with black grid. No need to test using the other grids. Stare at the dot in the middle of the grid. While staring at the dot, describe the grid. It is important not to look around the grid. A normal test result will show equal sized boxes/grid. An abnormal result would be, curved/wavy lines, missing lines, shadows, moving lines, etc. Take a screen shot and draw the findings on the image. Save the edited image.
(3) COLOR VISION
There are 16 color plates. Identify each number and list down the number you see per plate.
Submit all images via the NOW SERVING App. Go to the chat box/text box and click on the clip to attach the 2 Alphabet screenshots, 2 Amsler grids, and the color vision test results.
