"The prism is designed to reduce binocular eye fatigue and reading stress", said Dr. Kinkade. "The closer the book is held to the eyes, the more the eyes must turn in for binocular viewing. Without prism, there is a limit to how much the eyes can naturally and comfortably turn in."
There are also limits to the amount of prism that can be beneficial in a prescription. Twelve units of prism in each eye is often the practical limit. At a 4" viewing distance patients may be better off reading with one eye; the best eye. At this point the prescription is changed from PMRs to monocular microscopic glasses (very high power for one eye only).

The macula is an extremely important part of the retina used for seeing. It allows us to focus and carry out many vision related duties like reading, writing, driving and crafts. The macula is essential for crisp detail vision.
Dry macular degeneration is considered the most common (80-90%) and consists of yellow deposits (drusen) developing in the macula. In dry macular degeneration, blind spots develop within the line of vision. The decrease in vision is usually gradual and takes many years to develop. There is not effective treatment for this form of the disease.
Wet macular degeneration is more prone to rapid and severe vision loss if not treated. In this cond
