Your Oakville Optometrist Helps Your Understand Your Ocular Diagnosis

What Does 20/20 Vision Mean?

The sharpness of your vision is measured at a distance of 20 feet; so if you have 20/20 vision, it means you can clearly see what most individuals should be able to see at 20 feet. As such, 20/20 vision doesn’t imply perfect vision.

What is Amblyopia?

Amblyopia is also known as lazy eye. It occurs during the early stages of life, usually before 6 years of age. It is not a disease and it doesn’t cause blindness, but the central vision is impacted—the peripherals remain intact. This results in a poor link between the eye and the brain, causing a “lazy” eye.

What is Astigmatism?

When your cornea or lens is irregularly shaped (more oval than round), it causes blurred vision at every distance. This is called astigmatism. It is not a disease and clear vision can be achieved with eye glasses or contacts.

What is Colour Deficiency?

Usually incorrectly called colour blindness, colour deficiency is when you have a hard time deciphering colours and shades. It can be inherited or be the symptom of trauma or disease. Some affected individuals can’t identify red and green shades while others can’t identify blue and yellow shades.

What is Presbyopia?

Presbyopia is when you find it difficult to focus on objects close to you. This happens because the crystalline lens of your eye has become inflexible (for your eye to focus, elasticity is needed). Often, prescription reading glasses, bifocals, trifocals or contact lenses will correct presbyopia.

Cataracts, Glaucoma and Macular Degeneration Detection for Oakville Patients

Schedule an eye exam at Bronte Optometry to ensure the health of your eyes and detect eye diseases like cataracts, glaucoma and macular degeneration as soon as possible.


A cataract refers to the eye’s lens when it becomes cloudy in appearance, thereby impairing vision as light cannot focus on the retina to produce clear images. There are several variations of cataracts, but most are due to the lens’ chemical makeup being altered and may be a sign of disease. Three common types of cataracts are:

  • Cortical cataract
  • Nuclear cataract
  • Posterior capsular cataract

In Canada, glaucoma is the second leading cause of blindness. It classifies a set of disorders where the eye tissue damage is at least partly caused by pressure, or sometimes called intra-ocular pressure (IOP). Early detection via regular eye exams is ideal for treating glaucoma, as the condition’s symptoms are gradual and subtle, and if not identified, glaucoma can cause blindness.

Macular Degeneration

The part of your eye that illustrates fine details like face recognition is the central vision, and this is the part of the eye that is affected by macular degeneration (ARMD). With ARMD, your peripheral vision remains clear but details will not be visible. This condition is mainly caused by age; those older than 50 years are at greater risk. Genetics, smoking, exposure to UV rays, high blood pressure, diabetes, arteriosclerotic vascular disease all increase your likelihood of developing ARMD. There are 2 main types of ARMD:

  • Dry (a common form of ARMD and refers to the gradual breakdown of the retina’s light-sensing cells)
  • Wet (a less common form of ARMD and is caused by the growth of abnormal blood vessels that bleed, damaging central vision)

NON-Surgical Therapy

Understanding Your Ocular Diagnosis with your Eye Doctor in Oakville

At Bronte Optometry, we offer vision therapy treatments that provide our Oakville patients with a non-surgical solution to correct certain vision problems.

Vision therapy may treat:

Vision Therapy to Strengthen Visual Skills

Vision therapy works to develop and strengthen your visual skills, including tracking, vision perception, focusing and eye teaming.

Tracking Skills

Your ability to follow lines of text involves your tracking skills. This is controlled by your oculomotor system, which controls your eye movements. Yours eyes’ tracking skills involve other vision abilities, such as:

  • Pursuits (ability to smoothly track moving targets)
  • Saccades (ability to shift focus quickly)
  • Reading saccades (ability to move in a line from left to right without moving above or below the line)

Vision Perception Skills

This refers to your ability to interpret, analyze and understand what you are seeing.

Focusing Skills

Your focusing skills control your ability to clearly see objects close up and for prolonged durations of time. It also impacts your ability to easily switch your focus on objects close to you to objects that are far from you.

Eye Teaming Skills

Your eye teaming skills are what prevent you from having double vision. These skills control how each of your eyes work in unison.
