The speed of light is significantly faster than the speed at which your eye sees an object once you open your eye. The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second). This means that light can travel a distance of about 7.5 times around the Earth in just one second.
On the other hand, the speed at which your eye sees an object is determined by the speed at which light travels from the object to your eye, as well as the time it takes for your visual system to process the incoming light signals. While the actual process is complex, it generally takes a fraction of a second for your eye to capture an image and for your brain to interpret it, resulting in your conscious perception of the object.
Therefore, the speed at which your eye sees an object is much slower compared to the speed of light.
