What
is an Optometrist?
An optometrist is a doctor of optometry who is trained
to perform eye examinations for all ages. Optometrists
are primary health care professional who examine, diagnose,
treat and help prevent diseases and disorders of the visual
system, the eyes and related structures.
An optometrist is required to do a minimum of 3 years
in a bachelor of science program at university, followed
by 4 years of professional school at a School of Optometry.
Optometrists are licenced by the College of Optometrists
in British Columbia, the profession's provincial regulatory
body.
What
is an Ophthalmologist?
Ophthalmologists are physicians who, after graduating
from medical school, undertake several years of post-graduate
training in the diagnosis and treatment of diseases of
the eye. Eye surgery is preformed by ophthalmologists.
Patients require a referral from their optometrist or
family physician to visit an ophthalmologist.
What
is an Optician?
Opticians supply, prepare and dispense optical appliances
based on prescriptions prepared by optometrists and ophthalmologists.
Opticians in BC complete a 6 month to one year training
program after which they take a national examination that
enables them to dispense eyeglasses. Additional training
is required to dispense contact lenses.
What
is a sight test?
A sight test, more accurately called a refraction, determines
a spectacle lens prescription by relying on a combination
of computerized tests using automated equipment.
The comprehensiveness and accuracy of these automated
sight tests is limited. Eye muscle co-ordination is completely
ignored, and the test results can be influenced by eye
fixation and alignment, pupil size, corneal or lens irregularities,
and something called instrument myopia. This last problem
is caused by the eye's tendency to have its focus altered
by the device being looked through. This can lead to an
inaccurate measurement of refraction.
Sight tests will completely overlook many serious problems
and diseases that do not blur a person's vision at all
or until the disease is more advanced. Some of these include;
glaucoma, Type 2 diabetes, brain tumours, cancer of the
eye, high blood pressure and retinal detachments. Early
detection of these conditions is important to be able
to protect not only the health of the eyes and the clarity
of vision, but also the patient's overall health and maybe
even their life. Having a refraction (a sight test) done
without an eye health examination presents serious risk.
The regulatory bodies of medicine and optometry will
not allow their members to provide refractions without
also doing a complete eye health examination. In other
words, ophthalmologists and optometrists are not allowed
to sight test as it is considered to be dangerous for
the public.
Ocular
health can only be certified by a complete ocular examination,
by an Optometrist or Ophthalmologist.
On
May 1 2010 the BC government allowed opticians to perform
sight testing without the supervision of an optometrist
or an ophthalmologist.
The
College of Optometrists of BC, the BC Association of Optometrists,
the College of Physician and Surgeon and the BC Medical
Association have all criticized the sight testing regulation
as being a serious health risk. So far the government
has been unwilling to listen to the advice of the medical
community.
