Eye Exam (Overview)

An eye exam consists of checking the vision. If this is not normal a manifest refraction is done to determine if any glasses are needed. This is the test where the patient is asked which lens is better number one or two. Then the health of the eye is evaluated with a microscope called a slit lamp. To be able to see the back of the eye, the retina, the pupils are dilated.

Retinal exam: Floaters are usually not described as having colors. The description you provide does not suggest a single problem but may be due to pathology of the retina not observed in your exam. Did an ophthalmologist perform your exam? If so, may I suggest that you are having a variant of migraine. Ask your primary care doctor if this is a possibility. ...Read more

Are the eye drops that the optometrist uses prior to an eye exam safe?

Are the eye drops that the optometrist uses prior to an eye exam safe?

Yes: These drops will dilate your pupil (make the black dot in the center of your eye bigger) so the eye doctor can see the retina and inside of your eye better. Your eyes will be somewhat blurry and extra sensitive to light for a few hours after the exam, but it doesn't do any long-term harm. ...Read more

Why did a dilated eye exam hurt so much today? I think they had the light turned up high. Could it be photophobia?

Why did a dilated eye exam hurt so much today? I think they had the light turned up high. Could it be photophobia?

Light sensitivity: Dilation opens the eye so your ophthalmologist can see the periphery of the retina. Because of the increased light input, the eye is uncomfortable with this and going outside afterwards in the sun can be painful. This is temporary photophobia which will disappear when the dilation recovers. ...Read more

How do I read the results of my eye exam to know how bad my vision really is?

How do I read the results of my eye exam to know how bad my vision really is?

Difficult: A problem is that the number you receive for your eyeglass prescription does not easily correlate with the snellen fraction (the one that says 20/20 or whatever). So for instance a +2.00 correction might see 20/40 uncorrected while a -2.00 (note the sign) correction might see 20/100 uncorrected. Ask your ophthalmologist how bad your vision is in a meaningful way if this is important. ...Read more

Recent diagnosis of B12 deficiency, level was 169. Can low levels affect my vision? Eye exam in a month should I let opthamologist know about this diagnosis?

B12 and the vision: There are some reported vision problems found with B12 deficiency, though this deficiency is not well known for causing these problems. Eyelid twitching (myokymia), blurred vision, double vision, and nystagmus (back and forth movements of the eyes) have been reported. Since B12 deficiency can affect the myelin sheath around nerves, many neurological symptoms can result, including visual. ...Read more

What do they do in a normal eye exam?

Dilated exam: A typical new patient examination has three parts: refraction to determine whether you need glasses, checking the health of the front of the eye (from the cornea to the natural lens), and dilation. Although most people dislike the effects of dilation, it is necessary to allow the doctor a view of the structures in the back of the eye. Pressure is tested and the nerve is checked for glaucoma. ...Read more
