Over 70% of adults in North America need corrective eyewear. This statistic isn't surprising as we use our eyes very differently than we did even 20 years ago. If you
monitor your 'eye activity' on a daily basis, you will most likely realize your depth of focus is often fixed and limited to one activity for many hours.
For instance, if you work on a computer or spend periods of time online or watching t.v, you're limiting your focus. If you're a truck driver continuously looking at the road ahead, once again, you're limiting your point of focus. It's difficult to remember to take a break to care for your eyes, but there are some very simple techniques which can often help increase eye vision dramatically!
