How much do you know about the pupils of your eyes? Perhaps you haven’t given much thought to this black-colored circle in the center of each eye, but they play a vital part in your eyesight. Each pupil is surrounded by the iris, the portion of the eye that is tinted in a variety of colors (brown, blue, green, hazel, etc.).
At the office of Optivision, we use our extensive knowledge of the whole ocular system and the complexities of the eye to fit you with the perfect lenses and frames. Our team is made up of friendly, highly trained specialists who are eager to help you feel comfortable and relaxed while benefitting from the very best in optometric care.
While the average adult’s pupils vary between 2 and 4 millimeters in bright light and 4 to 8 millimeters in dark environments, you should know that if a pupil doesn’t change in size in response to alterations in lighting and gaze, there might be something wrong.
The sizes of your pupils change throughout the day. They shrink in bright environments so less light can enter your eyes. Conversely, they enlarge in dark settings so your eyes can take in more light. Pupils’ sizes also change in relation to the distance from an object at which you’re looking—such as while reading a book compared to while driving. And here’s one of their unusual traits: To a certain extent, one pupil can expand or contract to light and distance independently of the other pupil.
The pupils’ sizes can also change in reaction to your emotions, such as when you feel excited or nervous, or if you see someone laughing or crying. Pupils tend to enlarge when you’re engaged in a task that requires deep concentration, such as intricate sewing, working on an intricate math problem or studying for a test.
These sensitive little back dots also respond to prescription, over-the-counter and recreational drugs. Medical professionals get a good look at the innards of your eyes by using drops to dilate or widen them. Changes in pupil sizes can also indicate the use of illegal or recreational drugs, specifically cocaine, LSD, Ecstasy, heroin, methamphetamines, and ketamine.
We at the office of Optivision are committed to the health of all of our patients. We’ve earned the trust of all of our patrons and look forward to earning yours. For more information about our practice and many services, please don’t hesitate to call us today.
