The macula is the small part of the retina that allows you to see fine details in color. Macular degeneration causes a blank spot in the middle of your visual field. As the condition worsens, you lose your ability to read or see faces. There is no cure for this affliction but there is hope for one in the future.
Humans & our primate relatives are unique when it comes to the perception of color. Among the mammals, only we have the ability to see our world in full color.

At some time in our lives most of us are faced with print that is too small to read. A frequent question we get asked is “how strong a magnifying glass do I need” to read a book, newspaper, pill bottle, contract or map? For most people, a simple & inexpensive hand held magnifying glass is all you need.
