Eighty (80%) of learning is visual. One in six children have visual performance problems. A child may have 20/20 vision but still have learning problems due to inefficient visual skills and/or perceptual problems, making it difficult for the child to read and learn.

The Canadian Association of Optometrists (CAO) recommends all children have a complete vision examination between one and three years of age and again before entering school. It is recommended children to be seen yearly thereafter, even in the absence of symptoms.

Vision Correction

Low Vision

What Is Low Vision?

Partial vision loss that cannot be corrected causes a vision impairment known as "low vision." A person with low vision has severely reduced visual acuity or contrast sensitivity, a significantly obstructed field of vision -- or all three. Some of the most common causes of low vision.

Cataract



A cataract is the clouding of the eye's lens that can cause vision problems. Understand the condition, its symptoms, diagnosis and surgical treatment options.

Diabetes-Related Eye Disease



Did you know that diabetes is one of the leading causes of blindness? Diabetics can develop eye disease such as diabetic retinopathy -- the most common diabetes-related eye disorder -- as well as glaucoma and cataracts. Find out about diabetes and vision loss -- plus how to manage diabetes to reduce your risk of developing eye disease.

Glaucoma



Glaucoma encompasses a group of diseases that can damage the eye's optic nerve and lead to vision loss, even blindness. Many treatments, including medication and surgery, can help glaucoma patients. Learn more about the disease, its symptoms, diagnosis, as well as treatments.

Macular Degeneration

Macular Degeneration is the most common cause of vision loss among people over the age of 60, macular degeneration impacts millions of older adults every year. The disease affects central vision and can sometimes make it difficult to read, drive or perform other activities requiring fine, detailed vision. Here, you'll find all you need to know about the disease, symptoms, diagnosis and treatments.

Retinitis Pigmentosa



Retinitis Pigmentosa (RP) is the name given to a group of hereditary retinal diseases characterized by progressive loss of visual field, night blindness and reduced or absent electroretinogram (ERG test) recording, which indicates that a large portion of the retina is damaged.
