Visual Acuity range 8M to .2M (20/400, 6/120 to 20/10, 6/3 equiv.)
Two smaller groups 2M to .20 M for repetitive vision testing (20/100, 630 to 20/10, 6/3 equiv.)
Visual Acuity range 2M to .32M (20/100, 6/30 to 20/16, 6/4.8 equiv.)
This near point vision chart features two smaller groups of optotypes for repetitive testing. This is helpful because two groups will lessen the possibility of unwanted memorization while testing. Non memorization leads to more accurate vision records and higher repeatability. Eye chart is great for testing pediatric patients.
