I am an optometrist, and I still get kids in for their first eye exam with terrible vision. Visual loss due to the need for glasses does not happen suddenly, so I know these kids were handicapped with poor vision for a long time prior to coming in. Parents often wait until the child complains loudly. I'm sure the situation was even worse in the 20's when there was less availablility of care, no insurance, and scarce dollars to pay for non-urgent care. Al
