Normal Pupil Size Chart


This is the chart used to see normal pupils. The patient must eliminate the correction from the eye. The nurse uses a distant target with three outlines to correct the patient’s eyes. If the patient cannot see on the red filter, then the nurse will use another method and the patient must adjust the color. Patients can lead to the accommodation with small targets. This is related to narrowing of the pupil.

The nurse must have a millimeter ruler and a transilluminator to perform this test. The ruler can be replaced with a Gauge pupil. The pupils can be measured under normal light conditions using a ruler and the patient focuses on the distant objects seen before the eyes. This measurement is done when the eye test is not accommodating to an object. Nurses should keep the ruler out of the patient’s eyes to avoid an accommodative reaction. This will measure the pupil accurately and precisely. The ophthalmoscope will become a living flashlight so that it can measure pupils from a distance. Both pupils should be illuminated with the same intensity. Normal lighting can give you a normal pupil size of about 3.5 mm and 1.0 mm to 10 mm.

Your pupils are at a distance of 1 mm. There are some people with different pupil sizes called anisocoria.

If you find that anisocoria can cause problems, then you can report it to the nurse.
