The most important tool a vision screening professional uses to measure eye health is a
Titmus vision tester. However, vision testing is not always considered to be an important part of an eye examination by busy vision screening professionals. The fact remains though that there is no better way to check on the progression of many eye diseases than a good vision tester.
The best
vision testers are able to measure visual acuity, potential visual acuity,
contract sensitivity, glare and color. Good
vision testers should require no
physical interaction and should automatically refract and allow minute
refinements in sphere and cylinder to provide the best optimal subjective
refraction. Vision testers should offer 16 white LEDs and a diffuser system for
thorough lighting. Two optical paths
typically are provided, which is key for patients who wear glasses with
protective lenses.
It should be
able to perform many vision screening tests in one sitting, including distance
and near visual acuity testing, astigmatism, phorias, stereopsis, fusion, ARMD,
glare testing, contrast sensitivity and potential acuity testing. The device
should be lightweight (10 pounds or less), and adaptable to each patient and
allow them to sit in a relaxed position throughout testing. Some vision testers
also do peripheral visual field analysis. It also should have user-friendly
software to save and print patient data and results. All of the tests should be finished within 2-4
minutes.
The latest
generation of vision testers provides vision screening professionals with all
aspects of vision assessment in one rapid screening device. In fact, a top
notch vision tester – such as the
Depisteo Vision Tester – is as important as a Strabismoscope!
