Whilst most of us have our eyes checked reguarly, very little thought is given to depth perception.
I hope this blog gives you some food for thought.

Ive been very interested lately about how our eyes work (prob due to me getting really into photography over the past year +)
one thing i have commented on here before is peripheral vision and how important that is in riding.The interesting article I read is that we shouldnt jump out focus from one item to another. e.g. from a car to a gap, to a pothole. as each jump causes a loss in vision, instead we should use a smooth, slow swooping movement.
I get my peripheral vision tested during my annual eye test (contact lens wearer).
The phenomenon you are referring to is circadian vision.
I’ve heard of circadian rhythm,but not vision
It gets covered on the BikeSafe course. I’ve also asked my optician for comment on TC’s post.
The primary circadian clock in mammals is located in the suprachiasmatic nucleus (or nuclei) (SCN), a pair of distinct groups of cells located in the hypothalamus. Destruction of the SCN results in the complete absence of a regular sleep–wake rhythm. The SCN receives information about illumination through the eyes. The retina of the eye contains “classical” photoreceptors (“rods” and “cones”), which are used for conventional vision. But the retina also contains specialized ganglion cells that are directly photosensitive, and project directly to the SCN, where they help in the entrainment (synchronization) of this master circadian clock.[66]
