The images perceived are blurred in far vision, but remain clear in near vision.
The eye must make an effort to see at all distances, resulting in visual fatigue or blurred vision.
The images perceived are duplicated and distorted. Most people have some degree of astigmatism.
Difficulty focusing near vision. Presbytia generally begins between ages 40 and 45 and is related to aging.
A visual condition in which the eyes are not aligned together.
The crystalline lens of the eye, which is normally clear, becomes clouded and opaque. Vision then becomes blurred. Nearly 50% of people over age 65 are affected.
An increase in pressure within the eye, which damages the optic nerve. This damage may result in major vision loss, and even blindness if untreated.
A condition that blurs the central vision without affecting the peripheral vision. Generally associated with aging, this is the main cause of blindness in North America among adults over age 55.
Alteration of the tiny blood vessels that supply blood to the retina. Nearly 40% of diabetics have mild signs of diabetic retinopathy and 3% of them suffer from severe visual loss because of this disease.
This is a treatment to increase the transparency of eyeglasses while reducing the annoying glare of the light around you.
Scratch-resistant treatment allows protection of the lenses against scratches in normal use.
Polarized glasses are made from a polarizing film, which is applied in the factory to the front face of the lens. The film is then coloured. This film filters light rays and reduces dazzle (caused by surfaces such as snow or water), thus improving vision under high-luminosity conditions.
This is a lens that improves the clarity of images, offers high-quality contrasts and broadens the fields of vision, regardless of the luminosity. Manufacturing of these lenses is based on precision work, known as digital surfacing.
Digital surfacing is a process used to apply the design to the lens. Digital surfacing offers greater precision than traditional technologies:
1- a digitally controlled diamond tip working with a precision of 1/10 of a micron;
2- a flexible, unique and patented tool, allowing perfect polishing of the surface;
3- exclusive control methods, essential for an impeccable result for each lens produced.
There is no age limit for wearing contact lenses, but you must be able to maintain them or have them maintained.
If you do not notice anything abnormal, it is a good idea to bring your child to visit us around age 2½ or 3.
By a vision examination with techniques adapted for children (for example: drawings).
Your complete annual eye examination allows:
1) control of the natural evolution of your vision;
2) detection of eye problems, such as glaucoma and cataracts;
3) evaluation of the impacts on your eyes of a health problem, such as diabetes;
4) ensuring your visual efficiency at all times.
Technically speaking, our specialists examine your vision and the health status of your eyes.
The specialists examine visual acuity, with and without eyeglasses. Visual acuity is the ability to distinguish details. It is examined by a classical eye chart test. The refraction examination measures the power of the eyes. This is the stage at which the various degrees of myopia, hypermetropia, astigmatism and presbytia are verified. Convergence is the ability of the two eyes to move inward to focus on a point in space (for example: a word in a book). Focus is the ability of the eyes to adjust, regardless of the distance from which you are looking. Insufficient focus results in blurred vision. Depth perception corresponds to the perception of colours in three dimensions. It requires the total participation of both eyes. The specialists also study eye movement. Given that the eyes move in every direction in coordination, the movements must be flexible, easy and precise so that you can read and write efficiently.
B) Eye Health
To examine the visual field, the optometrist measures the space that an eye sees when staring straight ahead. The optometrist also examines the fundus oculi to evaluate the health status of the back part of the eye. The eye is the only part of the human body where the veins and arteries can be seen directly. Biomicroscopy is used to evaluate the condition of the cornea, the iris, conjunctivitis and the crystalline lens. The optometrist also examines neurological integrity or the reactions of the pupils to light, the condition of the lachrymal system, which provides information on the integrity of lachrymal gland tissue and intraocular pressure, particularly in people age 40 and over, when necessary. If the internal pressure is too high, this can cause retinal damage.
This vision specialist’s main role is to perform the ocular-visual examination. Having completed five years of university training, the Doctor of Optometry is the front-line professional of ocular-visual health. In addition to the vision examination, the optometrist is trained to diagnose and treat various eye disorders and diseases.
The dispensing optician, who holds a 3-year college diploma (DEC), advises you and installs or replaces a product adapted to the characteristics of your eyes and your prescription.
The ophthalmologist is a medical specialist in the diagnosis and treatment of diseases and anomalies of the eye and its annexes. This professional is trained to perform a complete evaluation of the visual function, examine the health status of the eye, and treat the problems determined, by a therapeutic or surgical approach.
