Hi everyone, working on solving some visual acuity problems and could use some help on what steps to use
1) in a 20 feet lane if the patient is seated at 15 feet and obtained 20/20, what is their actual acuity?
2) if a patient can see 20/20 at 4 feet, what is their acuity at 20 feet?
3) if a patient can see a letter that 10mm at 13 feet what will their acuity be at 5 feet?
4) what will the size of a 20/20 letter be if they are in a mirrored 10 feet lane with the chair 4 feet in front of the chart?
Would greatly appreciate any help
