You can tell them apart because the light from each source is traveling through your eye and hitting a different set of light-sensitive cells called photoreceptors.
If you move those lights closer together, they'll start hitting photoreceptors that are closer to each other, especially because as the light travels through the eye, it spreads out a little bit.
You have photoreceptors on your skin, and if light touches your skin, it can actually disturb your sleep.

This is where those rods and cones, those photoreceptors are.

When we talked about the eye, we talked about photoreceptors and how we see.
Photoreceptors take in light, then change the light into a signal.
Yes, mantis shrimp and many other aquatic animals have the ability to see far more colors than we can because they have more photoreceptors in their eyes.

and it will change the ratio of red light to far-red light. Now plants have these photoreceptors
Now plants have these photoreceptors called phytochromes,
Humans have three photoreceptors in our eyes.

Thermoreceptors respond to changes in temperature, photoreceptors react to light, chemoreceptors pay attention to chemicals,

Blue light triggers the photoreceptors in our retina to send a signal to our brain to suppress the release of melatonin.

and that's where the photoreceptors in, in, in all life first evolved.
