The use of a chart called the “Snellen Chart”, which features random letters of different sizes, is used by your doctor to check your vision. You will then be given eye drops that will help your doctor better see the back of your eye. To see the back of your eye, your doctor uses a magnifying glass using a bright light, your doctor can then see if there are any areas such as; blood vessels in the front of middle parts of the eye, the back of the eye and the optic nerve area, that may be damaged due to diabetes.
Another device used is called a slit lamp which allows the doctor to clear the surface of your eye (cornea). The doctor may also take photos of the back of your eye to get a more detailed exam.
After your eye exam, your vision will be blurred for about 6 hours, this is specifically if you had had drops in your eyes during your exam. It will be harder for you to focus on things that are near to you, we highly encourage that you have someone with you at your appointment to assist with your transportation from your exam. Sunlight can damage your eye, during this time, please wear dark sun glasses or shade your eyes until the effects of the drops wear off.
