A vision improvement coach has urged people to make sure they exercise their eyes as well as the rest of their bodies.
Walter Parij, based in Winnipeg, told the London Free Press that wearing glasses could cause eye muscles to weaken and said that these muscles need to be exercised to be kept strong.
He suggested exercising these muscles through such means as looking at things far away and close up or rolling their eyes in circles.
Furthermore, a healthy diet is important, with Mr Parij especially recommending that people get enough zinc.
"Really effective eye care means spending a few minutes every day exercising your eyes," he said.
Medfinds writer Kimberly Beauchamp recently quoted an article from Archives of Opthalmology which said that eating fish and nuts once or twice a week helps to fight age-related macular degeneration, which can cause sight loss.
Recommended foods included wild salmon, mackerel, sardines, pecans, Brazil nuts, walnuts, blueberries, cherries, strawberries and red apples.
