Have You Ever Wondered What Causes Myopia?
Myopia is the medical term for nearsightedness. I think the biggest myth out there is that myopia is caused by excessive reading. This is because populations that have no formal education programs and who don’t read books have a myopia rate of less than 2%. That’s why brainy children are always seen wearing glasses. Before you pat yourself on the back and look down your nose at the people who don’t wear glasses, remember, it’s a myth.
Hermann Helmholtz vs. William Bates…..Who was Right?
In 1855, Hermann von Helmholtz performed experiments to show how the eye accommodates near and far objects. He noted that when an object was brought nearer to the eye, the curvature of the front of the lens increased. So he concluded that the changing curvature of the lens was the way the eye accommodated to near and far objects.
