How to determine patient acuity Here are some basic guidelines for rating acuity. Patients are rated on a scale of 1-4 based on some of the following: Level 1: VS X 1, A&O,independent care, 1-2 PO meds, saline lock, room air, 1-2 closed incisions OTA, no procedures. These are basic guidelines and can be tweaked for any unit.

Vision Tests Visual acuity tests are the most common tests used to evaluate eyesight. They measure the eye's ability to see details at near and far distances. The tests usually involve reading letters or looking at symbols of different sizes on an eye chart.

- Visual acuity and sensitivity to motion[edit] The visual acuity of the horse, or how well it is able to see details, is around 20/33. This is slightly worse than the usual 20/20 in humans, but much better than the visual acuity of dogs (20/50), cats (20/75), and rats (20/300).

- Reading charts are often used to measure visual acuity. Visual acuity measurements evaluate how clearly each eye is seeing. As part of the testing, you are asked to read letters on distance and near reading charts. The results of visual acuity testing are written as a fraction such as 20/40.When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read.A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet in order to see it clearly. Normal distance visual acuity is 20/20.Preliminary testing may include evaluation of specific aspects of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils respond to light.eading charts are often used to measure visual acuity.

Visual acuity test Visual acuity test. The visual acuity test is used to determine the smallest letters you can read on a standardized chart (Snellen chart) or a card held 20 feet away. Special charts are used when testing at distances shorter than 20 feet. Some Snellen charts are actually video monitors showing letters or images.

Simulating visual acuity Simulating visual acuity. The purpose of this page is to give an idea of how blurry your vision is when you don't use your glasses or contact lenses, or when you use a prescription which doesn't match your eyes. This is illustrated by simulating the blurry perception of a Snellen eye chart, which is commonly used to make eye examinations.
