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. Patent US 8,083,353 and International
Published Patent WO 2011/022428. For further information contact:
