“I thought Eyesight has to do with heredity”

It’s common for people to think that your vision has to do with your genetics. People think that because they commonly notice that a child has glasses as does the parent and vice versa.

However, this does not mean that it is the genetics. Similar to this, we could look at obesity. Obese parents are more likely to have obese children, but is it because of their genetics or is it because of their behaviors? Obese people eat more calories and exercise less and they are selecting the food and much of the activities of their children.

Similarly, myopic and hyperopic parents are choosing to use glasses as a response to blurry vision and are essentially stuck in their ways, unless they begin to entertain the notion that there is a true cause to their blurry vision and that they can do something about it.

But the real data to look at is the staggering increases in myopia that have occurred in the last thirty years. I haven’t checked in a while, but last I read – in the 1970’s in the United States the rate of myopia was around 23% and now it is around 42%. One cannot attribute genetics as the cause of that jump because the genetics have not changed that much – but people’s behaviors are. Furthermore, in the African American community the rate of myopia increased around three fold from around 13% to 38%.

People are spending less time outdoors and more time indoors. That means less time relaxing and getting natural sunlight and looking to the distance and more time using unnatural light (some that are known to be harmful directly and others that simply mess with bio-rhythms) and more time in small enclosed areas literally staring at screens.

For more than just our eyes, there’s a big difference between a video of a forest and being in an actual forest. When you watch a video you can pretend that it’s 3d, but it’s not. However, that pretend process may be quite harmful to your eyes because you are staring at the same distance from yourself and not moving.

Vision is more than just about having acuity and sharp resolution. Vision is a dynamic interactive process with the world. Three dimensionality, quickness of environmental appraisal, and ability to process experience are fundamental parts of vision that need to be looked at.

I wish you greater clarity than you’ve known.
