Includes red and green bars for color vision screening.
HOTV optotypes are great for testing preliterate children 3-4 years old.
The child must be briefly taught each optotype before testing and shown the response key included.
HOTV chart also includes red and green bars for quick color vision screening while testing acuity vision.
Chart Size : 9×14 in (23×35.5 cm). Chart Distance 6m / 20ft, Optotype : HOTV, Contrast Level : High

This takes the guessing out of pediatric vision testing and make recording more accurate.

Poor quality.The color is too dark. It's much darker than A4 paper.

I bought this to conduct the vision screenings in my high school because I did not like the chart that they had and theirs did not have the color blocks either. This is much more functional and easy!! All in one, you just need to hang this up and measure 20 ft away and mark that spot then either have the student cover their eye or use a small cup to cover each eye.
