How Do Our Eyes Compare with Cameras?

January 15, 2018

Have you ever taken a picture and noticed it didn’t turn out how you saw it? Have you ever wondered why this happens? Although our eyes and cameras both see images and have similarities, there are still a vast amount of differences between them. So how do our eyes compare with cameras?

The Aperture

One similarity between our eyes and a camera is the ability to control the amount of light which passes through the lens. Our eyes utilize the iris, which can relax and flex to control the amount of light. In a camera, the aperture can be adjusted to let in different amounts of light.

The Lens

A major difference between our eyes and a camera is the lens. In our eyes, the lens can change shape in order to correctly focus on objects which are at different distances. A camera lens, however, cannot, changing the focus requires you to move the lens closer or further from the film/imaging sensor chip. Our eyes also only have a single lens whereas a camera can have multiple lenses.

Dynamic Range

Another major difference and benefit of our eyes is their dynamic range in comparison to any camera. Our eyes have the ability to see both during the bright day and moonless night, only taking 30 minutes to adjust completely. Although there are cameras that can see in more darkness and withstand bright lighter, there is no camera with a greater dynamic range.

Caring for Your Eyes

Another major difference between our eyes and a camera is the fact that you can simply buy a new camera. Unfortunately the same can’t be said about our eyes. Scheduling regular eye examinations can help ensure your eyes are working properly and there are no risk factors for optical complications.
