I probably missed it but I do not recall whether the increase is due to the increase in population; or did the "studies" say that the increase is for same people who did not need glasses suddenly needed glasses? As it is a numbers game, wouldn't it be likely that an increase of 1 million people will have a number of the million persons needing glasses; were they counted differently.
Same goes with increase obesity, diabetes, heart problems, etc. Never saw anything of a breakout of the numbers that excluded the increase in population. Is the study finally including non-eyeglasses users who had chosen operations on their natural lenses (karatomy?) or wear contact lenses?
More health services are now available for testing both eyesight and dental issues; and more people are more concerned about their health as the services are available(?).
