Seeing light is broken down into two parts - seeing, and light.
Light is a phenomena very unique in the world of physics as it exists with properties both reflecting a wave and particle, simultaneously. Light is emission of energy, which implies that there must be a source of said energy.
Seeing also has two components. You see, the human eyes are photoreceptors, which can detect light via the rods and cones in the eye. Other photoreceptors exist, most commonly the cameras on our phones.
These photoreceptors can detect different wavelengths of light. Our human eyes can only detect light in the visible spectrum, which ranges from around 380 nm to 750 nm. Your phone camera picks this up too. However, unlike our eyes, our phone cameras can also detect infrared light, and will see an IR led flashing -while our human eyes will not see the flashing.
Philosophically, seeing is basically the most important sense we have, especially in our technology driven world. Without it, it is difficult to navigate the world (not impossible though).
Does this answer the question well?
Welcome to Dinks, I promise I'm not always like this.
He definitely always is like this. Don't trust him for a second
