Dyop™ Vision Testing. Seeing clearly has never been easier. “State of the art” vision
standards from 1862 may no longer be adequate for today’s needs for literacy
and activity. Dyop™
images (short for Dynamic Optotype™)
utilize motion, distance, contrast, and color perception to create vision
tests based upon retina physiology rather than 1862 standards of literacy.
Our eyes developed as
survival sensors to detect motion and distance and color, and NOT just the differences between static letters such as ‘E’ and ‘C’. When you see the pixel images on an electronic
display, unless you are TOO CLOSE, you don't actually see the pixels that
make that image possible. Your eyes function just like the pixels in
the display so that you see the images without noticing the pixel response of
your retina photoreceptors. Dyop™
images measure that photoreceptor pixelized
response as your acuity.
Incrementally-scaled
calibrated Dyop™ combine the image
diameter (angular arc width), segment/gap stroke width, circumferential
rotation speed, color, contrast, and the pixelized strobic photoreceptor
refresh rate of to create an Acuity
Threshold as an indicator for both visual acuity and the refraction end
point. As a result, Dyop™ acuity tests are more precise
than static Snellen/Landolt tests, faster to use, and do not require literacy
let alone the ability to read English. Static
images get increasingly blurry as they get smaller or further away. Dyop™
image rotation seems to disappear at the Acuity
Threshold to give that more precise indicator based upon the angular arc width of the image and your viewing
distance. Calibrated
Dyop™ images are intended as a
global replacement for both Snellen and Landolt optotypes. View the Sample

Acuity is
a measure of how clearly you are able to see images. Conventional
vision tests use static images such as the Snellen
letters and Landolt
ring whose measure of visual acuity is
partially based upon comprehension.
Static image acuity measures the ability to detect the gap in an
image, is frequently measured using negative stimulation (even though you
don’t “see black”), and depends upon fixation to minimize the saccade
process. Dyops™
take the guesswork and excess visual stress out of clear vision because you
either see the rotation at the Acuity
Threshold (your precise point of acuity/refraction) or you don’t. |
