Actually it is. If your vision wasn't high definition, you would not be able to notice the difference between high-definition displays and regular displays. That is also why you can tell what is bad, since your eyes can detect much more detail than what an image you don't like that much has.
Each human eye has a coverage of about 160°. The coverage overlaps giving about 90° of stereo vision. The foveal vision (high definition in the center) is less than 2°.

There are roughly 120 million rod cells in the human eye. Rod cells are photoreceptor cells in the retina responsible for vision in low light conditions.
Glaucoma is a group of eye conditions that can damage the optic nerve and lead to vision loss. It is often caused by high pressure inside the eye, which can damage the optic nerve over time if not treated. Early detection and treatment are important to prevent vision loss from glaucoma.
