Tips and Recipes for Better Eye Health
Here, we’re talking eye health and aging with Vancouver-based optometrist Dr. Pavan Avinashi.
Our eyes, like our skin, lose elasticity as we age affecting our ability to focus at close objects and that fine print. The condition is called presbyopia, the Latin translation of which is aging eye, notes Dr. Avinashi. “It starts pretty much in your 40s and it’s a gradual, consistent process that affects every human being,” he confirms.
So, what can we do? It turns out Avinashi recommendations start with what we shouldn’t do. That is to pick up a pair of generic readers in the drugstore aisle.
“They’re basically a magnifying glass. And using something that may be the incorrect strength can actually stress and fatigue the eye further,” he says.
See an eye doctor when you note vision changes
In addition to ensuring the correct strength, a prescription can correct for conditions such as astigmatism – irregular curvature of the cornea affecting as much as 40 per cent of the population.
Wear sunglasses, year-round
Also similar to our skin, sun exposure results in oxidative damage to the eye. Although he says that 50 per cent of the damage is down by the time we’re 20, Avinashi’s advice includes donning shades year-round. Look for lenses that block 100 per cent of UV rays and also absorb most HEV rays – both of which reach us whether it’s sunny or not.
Combat screen strain
We spend an average of 8 hours and 41 minutes per day in front of an electronic device and that can cause asthenopia, or eyestrain characterized by blurred vision, sporadic double vision, premature tiredness, and the inability to maintain a consistently clear image at a distance. Avinashi says to follow the 20-20-20 rule: every 20 minutes, look away for 20 seconds and focus on something 20 feet away.
Blinking helps regulate tear film and flow, which helps keep our eyes naturally moist. But we blink up to 50 per cent less often when focused on a screen, which can contribute to dry eyes. As can certain medications as well as hormone changes, most often in women as they age. Make a point to stop and actively blink through the day Avinashi advices, and stay well hydrated . (Dietitians of Canada recommends 2.2 litres (9 cups) of fluids each day for women and 3 litres (12 cups) for men.)
Avinashi says multifocal contact lens technology has come a long way since coming to market about 15 years ago. “Not everybody, but I’d say 95 per cent of people can get on with multifocal contact lens.”. Contact lenses inherently disrupt the eye’s natural lubrication and as we age our oil glands and our tear glands don’t function to the same degree. He recommends Alcon Dailies Total1 Multifocal contact lenses as their patented technology releases moisture molecules into the eyes as you blink. Bye, bye bifocals!
Avinashi also recommends seeing your eye doctor regularly. Not only to keep your prescription up-to-date but also to screen for conditions such as age-related macular degeneration – the leading cause of vision loss among older adults.
Research has also shown that a healthy diet including carotenoid compounds such as beta-carotene, lutein and zeaxanthin, and vitamins C and E. zinc and omega-3 fatty acids are important for eye health.

Long incidentally notes that an added advantage of multifocal contacts is that the lenses help keep him from crying when cutting onions. Bonus!
St. Lawrence Salad by Brad Long
Browned Butter Vinaigrette Ingredients:
8 tbsp. (125mL) salted butter (1/4 lb/125g)
1 tsp. (5mL) minced shallot
3 tbsp. (45mL) cider vinegar
3/4 tsp. (4mL) honey
1/4 tsp. (1mL) dijon mustard
Kosher salt to taste
2 carrots (or other fresh roots such as parsnips or beets)
About 6 oz. (170g) mixed salad greens and micro greens (about 12 cups/3L loosely packed)
About 1/4 cup (60mL) cold cooked grains (such as quinoa, pearl/pot barley, spelt)
About 1/2 cup (125mL) raw pecans or other nuts, toasted
1 pear or other tree fruit (such as apple or peach), thinly sliced with skin on
About 1/4 cup (60mL) dried cranberries (or other dried fruit such as raisins or cherries)
About 2 oz (60g) crumbled chèvre (soft, unripened goat’s cheese) or other young cheese
Fresh flat-leaf parsley leaves
For vinaigrette, in medium saucepan, melt butter over high and watch closely as it foams, falls and foams again while the solids start to brown and smell like toasted hazelnuts. This may take 3 to 5 minutes depending on your stove. Remove from heat as soon as the butter browns so it doesn’t burn.
Place shallots in medium stainless steel bowl. Place fine-mesh strainer over bowl. Slowly pour butter through strainer, being careful as it will foam; discard solids (little browned bits). Let cool 5 minutes. Whisk in vinegar, honey and mustard. Taste; adjust if desired. Whisk again. You should have about 1/2 cup (125mL).
