    Optometrists believe that the reason for this is that we’re tending to be inside more than we used to be, rather than going outside as much, so our eyes basically aren’t getting as much exercise in looking at stuff far away.

      I’ve also heard the theory that eyes need ultraviolet light to grow properly, which is missing in artificial lighting.

      Yeah, I’ve noticed that my eyes focal point has become the distance to my monitor.

      You mean to tell me, that in this day and age, with half a zillion cars out on the road damn near every day, that people don’t go outside as much as they used to? Let alone have to look half a mile down the road to find the exit sign on the highway?..

        Myopia develops in children. If you have any, you’ll know they don’t generally look out of car windows.

          Oh, I’ve got myopia, like -5 vision, and yes I was born with it. That’s why I ain’t buying that whole ‘we don’t go outside as much’ theory for even a second.

          Edit: Thank goodness for glasses/contact lenses.

            So because you were born with myopia, you don’t believe that some people develop it later in life? What are you talking about?

              Do you even know what causes myopia at birth? The eyes aren’t properly spherical, they’re elongated. This doesn’t tend to change all that much over one’s lifetime either.

                You aren’t born with adult sized eyes. Your eyes grow as you grow, and their growth appears to be regulated by how they’re used. It’s covered in the article, maybe read it?

                  No shit Watson. It’s still all about the shape and proportions of the eye, not the size. Anyone with myopia can literally push their eyes in gently via the eyelids and see a bit better.

                  Your eyes don’t get longer from being indoors, you’re either born with longer than normal eyes or you aren’t. Some are even born with shorter eyes, called hyperopia (also better known as farsightedness).
