This video describes what the doctor sees when examining the retina (the light-sensitive tissue at the back of the eye), macula (the part of the retina needed for sharp, central vision) and optic nerve (which connects the retina to the brain).

Sharp vision depends on many factors. The parts of the eye work together to bend (refract) and focus light rays.

You might think your vision is fine or that your eyes are healthy, but visiting your eye care professional for a comprehensive dilated eye exam is the only way to really be sure.

Living an overall healthy life is good for your eyes. This includes: • Maintaining a healthy weight. • Eating healthy foods. • Not smoking.

Talk to your family members about their eye health history. It's important to know if anyone has been diagnosed with an eye disease, since many are hereditary. This will help to determine if you are at higher risk for developing an eye disease yourself.

This video shows patients how to use eye drops and ointments.

As you age, you are more likely to get flashes and floaters in your vision. Here is an explanation of what these are and when to get medical care.

Ptosis is when the upper eyelid droops down more than it should. If the ptosis is severe, it may block vision.

Brown syndrome is a problem with a tendon that attaches to the eyeball. In Brown syndrome, this tendon can't move freely. This limits the eye's normal movement. Brown syndrome is a rare disorder. It is usually present at birth (congenital). In some cases, it's acquired later in life.

Brown syndrome is a problem with a tendon that attaches to the eyeball. Most cases are congenital, which means they are present at birth. Here's what you need to know about this condition.

Your retina has special cells that detect color. If you have a problem with these cells, you may not be able to see some colors.

CVS is very common. Your eyes may itch and tear, or be dry and red. You may not be able to focus well. These problems are the result of a lot of computer use.

Convergence insufficiency (CI) is a problem with the way the eye moves. It makes it hard to focus on things nearby. When the eyes converge, it means they point inward (toward the midline) to focus on something close. With CI, the eyes have trouble doing this. One eye may turn out instead of looking inward. CI can cause blurred vision, double vision, and eyestrain.
