Wikipedia estimates that between 0.8 and 2.3 billion people worldwide are nearsighted or have the condition called myopia. But cheer up, myopes! According to Arthur Jensen, the noted education psychologist, chances are you’ve got a seven to eight IQ point advantage over friends and neighbours with better eyesight.
There must be a lot of smart people in Canada. Take those world figures and split the difference, say 1.5 billion myopes. It means that there are about 7.2 million Canadians who are wearing or could use glasses for myopia alone.
How many of you, though, will get another condition called presbyopia? Answer: Everyone.
Presbyopia is part of the natural course of events as we age. It is, simply put, the diminished ability to focus on near objects. Its causes are up for debate, but it is progressive, and the first symptoms are unmistakable: Difficulty reading fine print or reading in low light, blurred vision in switching focus from far to near objects and eyestrain when reading for extended periods of time.
Recent innovations in the production of corrective lenses have created a new breed of progressive high-definition lenses, which are polished with computer-controlled precision on the inner surface. By putting the refractive surface closer to your eye, distance transitions feel more natural, and it increases your field of vision by up to 30 per cent compared to conventional progressive lenses. Wearers of these lenses report diminished neck, shoulder and back pain as they no longer “aim” their heads as much. I have a pair, and it has made a huge difference for me. People who know me know that I used to store my glasses on my forehead when I was reading things up close but had to put them back on to work on a computer. I don’t do that anymore, and working on a computer with its different font sizes and web pages is much easier now.
