Vision is one of our most precious senses.
Yet we can have considerable loss in our ability to see without our being aware that the loss is actually taking place. Significant and often permanent loss of vision may be detected only after there have been several changes in eye glasses to improve vision. In such cases the underlying problem is not an error in glasses prescription, but due to an underlying medical condition. You are nearsighted. You have a history of high blood pressure.
