The Experimental Dyop Visual Acuity Test
(link above) is intended to be viewed at either 20 or 10 or 5 feet from your Personal
Computer monitor, and to give you a precise indication of your visual
clarity. Selecting the correct monitor
size and viewing distance insures that the rings are properly calibrated. The
SmartPhone test can be used on either an iPhone or an Android device. To use the Experimental Dyop Visual Acuity Test,
open the link for the test, fill in the value of your viewing distance from
the Monitor, and calibrate the monitor size using the “Calibration
Credit Card” image. Click the
Dyop logo to begin the test. Sit or
stand the desired distance from your monitor and observe the motion of the initial
Dyop rings. (See screen shots below). Use the mouse scroll wheel or the Up/Down screen
arrows to reduce the diameter of the Dyop ring to determine the arc width of
the smallest Dyop that can clearly be detected as rotating. That arc width is an indicator of your visual clarity endpoint. Since we actually see in Red, Green,
and Blue
rather than just Black/White, you
can also check your clarity in color.
There is an extreme likelihood that a preferential genetic perception
of Blue-on-Black
versus Green-on
White is indicative of symptoms of dyslexia, migraines, and epilepsy. Some visual conditions such as early onset
of glaucoma also have an increased deficiency to detect Yellow and Blue. The
images below are static screen shots
of the PC version of the test, and NOT
the actual test.
Your visual clarity may not be the
same for each eye (and differs for clarity in color). Check clarity first with BOTH EYES and then EACH EYE individually. Your visual clarity endpoint is the arc
width diameter of the Dyop® ring at the correct viewing distance. A 7.6 arc minute visual acuity endpoint is
equivalent to the Snellen 20/20 ratio. Example: If your viewing distance is 10 feet
from the Dyop ring,
and the smallest Dyop ring you can detect rotating
without using your glasses has a 15.2 arc minute width (13.5 diameter wide) then your visual clarity is similar to the Snellen ratio of 20/40. Note: Dyop
tests are for vision screening
purposes only and
are NOT a
substitute for an examination by a licensed vision care professional.
The computerized Dyop tests use
Adobe Flash and may be viewed virtually any computer using Google Chrome or Internet Explorer (with
ActiveX enabled) or Firefox or Safari or other graphics viewers such
as Irfanview
with the Flash Graphic
plug-ins and the free Adobe Flash Graphic Viewer enabled. To use the Dyop tests on a Tablet/SmartPhone, such
as an iPad or iPhone, you need to use the Adobe Flash SWIFFY HTML
Dyop test versions, however, the SWIFFY HTML tests will NOT properly display with older
versions of Internet Explorer. The Dyop® (Dynamic Optotype™) tests and concept are covered under U.S.
