The human eye and vision centres in the brain are quite complex. Detection of colour, depth, and central and peripheral visual fields are all important functions that help us perceive and interact with the world around us. However, just like the rest of the body, our vision steadily declines over time. One of the most common complaints that occur in adults between the ages of 40-60 years is trouble seeing objects nearby, such as difficulty with reading a book or working on a computer.
Other more complex issues can arise such as cataracts and age-related macular degeneration. Cataracts involve cloudy buildup within the lens of the eye. This can lead to opaque, blurry vision, faded appearance of colours, difficulty seeing at night and double vision. Proteins within the lens breakdown with age and clump together causing this cloudy discolouration[i]. According to the Canadian Association of Optometrist, an estimated 3.2 million Canadians have cataracts and most are over the age of 60[ii]. Age related-macular degeneration is a condition whereby the central part of the retina known as the macula, deteriorates slowly causing difficulty with focusing on objects such as during reading, driving, and observing fine details. Peripheral vision is not affected in age-related macular degeneration[iii].
Both of these conditions, as well as the normal and expected age-related decline in vision can be prevented or delayed by simple lifestyle changes:
Making better lifestyle choices, eating a balanced diet, regularly having your eyes examined by your eye specialist and supplementing with antioxidant rich formulas can help prevent poor vision and common eye disorders.
