Optometrist
in Toronto undertakes different tests to determine the condition of your eyes.
These can be as simple as reading the eye charts or complex like use of
high-powered lenses for visualization of tiny structures within the eyes.
Comprehensive procedures will take more than one hour based upon your doctor
and complexities/number of tests involved. Optometrist in Toronto would like to evaluate the eye health and your vision thoroughly. Here
are some common vision tests.
Visual acuity
examinations
It
is for testing the vision sharpness. The optometrist will use eye, projected
charts for the purpose. This is for visual acuity testing for various
distances. It can also be in the form of acuity hand held charts for measuring
the near vision.
Test for color
blindness
Many
people suffer from color blindness without even knowing this. A visit to the
optometrist chamber followed by conduction of proper tests can help to identify
this problem. Screening tests to check your color vision is one of the initial
tests that the professional will conduct in order to rule out such
possibilities. This not only helps identify hereditary deficiencies regarding
color vision but also underlying issues that can lead to color blindness in
future.
Cover test
A
number of tests are there for determining eye coordination and one of the
commonest among these is the cover test. Your optometrist in Toronto will ask
you to focus upon small objects present across room. Now they will cover each
eye alternately where you will need to concentrate on the given target with the
open eye. You will now repeat this procedure with objects now placed nearby
your vision. The doctor will use these for assessing movement of uncovered eye
to pick fixation target, an indication of Arabists. It can also be subtle
issues related to binocular vision leading to myopically/lazy eyes or eyestrain.
Depth
perception/stereo psis test
This
describes teaming of the eye enabling depth perception as well as the
appreciation of various 3 dimensional objects around us. In a common scenario,
your optometrist in Toronto will ask you to wear 3D glasses. Now you will look
at various patterns presented before you in the form of test booklet. The
patterns contain 4 circles small in size. Your job will be to identify the one
that seems closest to your eyes. If you are able to identify each one
accurately, this indicates effective teaming pattern for normal perception of
depth.
Colonoscopy
This
test is for writing your glass prescription. For this examination, you will sit
in a room with dimmed lights and focus on large targets. This is usually a big
E written on the eye chart. When you look towards the alphabet, optometrist in
Toronto will focus light on the eyes and estimate lens power for distance
vision correction.
These
are some of the corrective examinations that are undertaken by the optometrist
to ensure that the right diagnosis is done. To read more Click Here
