I've had my camera since I was in high school (I just recently graduated from college, so I've had it for awhile). My camera worked great--until a few weeks ago. Everytime I turn on the camera, if flashes E4 and won't let me take a picture. It doesn't always do this and will turn on with no problems at all. When the error message does appear, I have to keep pressing the power button until the error message turns off and I can take a picture or turn the camera off. Any idea to what this error message means? And if so, is it worth fixing?

An optometrist holds a Doctor of Optometry (O.D.) degree, which takes seven years of study to complete. O.D.s diagnose vision problems, diseases of the eye and related diseases. They are also responsible for prescribing corrective eyeglasses and contact lenses.

Difficulty: Challenging
Instructions
Things You'll Need:
Take numerous science and biology courses in high school.
Go to a college where you can take three years of pre-optometry courses. Consult your guidance counselor during your junior year about colleges that offer such a program.
Find and visit optometry Web sites with the help of a major search engine like Google or Yahoo. Look for information on optometry schools and their admission requirements.
Take the Optometry Admissions Test during your second or third year in college. The test will measure your academic and scientific knowledge.
Apply for admission to optometry schools accredited by the Council on Optometric Education of the American Optometric Association. Keep in mind that competition is great.
Complete your optometry school's four-year course of study and pass a written and clinical state board exam.
Apply for your state license after receiving your O.D. degree. You should ask your state's Board of Optometry well beforehand about its licensing procedure.
Consider a one-year postgraduate program if you want to become a specialist.
