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.
