Yes because of pupil dilation
Yes, there can.
There are three common ways: through a pupil dilation test, through tonometry, or through a visual acuity chart.
We do experience a form of time dilation in everyday life, but the effects are extremely small. Time dilation occurs due to differences in gravitational potential and velocities. In our daily lives, these differences are relatively insignificant compared to extreme situations, such as near a black hole or moving at speeds close to the speed of light, where the effects of time dilation become much more pronounced.
Time dilation always occurs, at ANY speed. The reason it was unknown for solong is that it doesn't become noticeable to us at any speed where we have anydaily experience. But as soon as we had atomic clocks capable of measuringinsanely tiny time differences, and began using them to look for time dilation,there it was, right in front of us, all over the place, in just the predicted amounts.

The procedure for dilation of the kidney?
Dilation
The type of dilation that occurs with a scale factor of 14 is enlargement. Any time the scale factor is larger than 1, it is enlargement.
While we do not presently (with our large relative mass) have the energy to reach any speed near the speed of light, we can observe particles that are close to that speed. Time dilation has been verified using such techniques. Also, even at slow speeds, time dilation is observable, but the precision of the measurement is very tight.

The opposite of dilation in math is contraction
Time dilation is an actual change in the passage of time due to the relative motion between two observers. It has been confirmed through various experiments and is a fundamental prediction of Einstein's theory of relativity.
