Most people should have their vision checked every two years, which may or may not include eye health tests, depending on your specific needs. If you’re due for an eye exam or if you’ve been experiencing frequent headaches or problems seeing your computer screen or street signs when you’re driving, contact Dr. Steven L. Cahan, an experienced and board-certified ophthalmologist practicing in Asheville, North Carolina. Dr. Cahan offers comprehensive eye exams to check your vision as well as your eye health. Call or schedule your appointment online today.
Like your annual physical, a routine exam checks the health and function of your eyes. Many eye conditions don’t cause symptoms in their early stages, and Dr. Cahan can diagnose and treat issues before they disrupt your life. Also, if you have a vision impairment, Dr. Cahan can prescribe corrective lenses like eyeglasses or contact lenses to correct your vision.
While you should have your vision tested every two years, everyone, including those who haven’t had prior eye health issues, should have a comprehensive exam with an ophthalmologist at the age of 40. This is when many people start to show signs of age-related vision and eye health problems.
When you check in for your eye exam, a member of Dr. Cahan’s team takes your insurance information and asks you to complete some paperwork.
Your exam starts with a few tests, including:
Then Dr. Cahan begins the refraction and slit lamp tests. The refraction test allows him to fine-tune your prescription. You look through a device and read lines of letters and he switches between a variety of lenses that you peer through, asking which option is clearer.
During the slit lamp test, Dr. Cahan carefully examines your eyes using a binocular microscope to examine the structure of your eye. You rest your chin against the machine and look into a light while Dr. Cahan looks into your eye. He may ask you to look up, down, or to either side so he can get a close look at all sides of your eye.
Occasionally, Dr. Cahan will need to dilate your pupils so he can examine the insides of your eyes in more detail. For a pupil dilation, he puts a few drops in your eyes that cause your pupils to open. Then he uses the slit lamp and other devices to examine the interior of your eyes. This test is especially important if you have a high risk of eye disease.
Your pupils may stay open for a short period of time, making you sensitive to light and unable to focus on nearby objects. You should bring sunglasses to wear after your exam and arrange for a family member or friend to drive you home.
