| 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 | This near point chart features highly calibrated Sloan optotypes. They adhere to the Snellen 5x5 grid, equal blur at threshold, and equal difficulty. Also, each optotype is recognizable. This near vision chart also feature these optotypes in an ETDRS | Tumbling "E" charts, also known as Illiterate "E" charts, feature the use of only one optotype. This makes testing illiterate and mute patients easier. The patient only has to gesture the direction they see the "E" facing. Also the design of the "E" |
