I forgot to include some photos from our visual acuity projects for our psychophysics class. We had to create our own VA charts, caluclate and size it accordingly, determine the patient population we wanted to design it for, determine the type of contrast sensitivity we wanted, the type of optotype (letters, numbers, symbols) we wanted to use, size, testing distances, illumination levels, etc. The list goes on! To summarize, making an acuity chart is not as easy as it looks. My partner and I made a near-vision acuity chart to screen for amblyopia in children under 6 years of age, with 90% contrast, at a testing distance of 75cm.
