The ciliary muscles in the eye contract to increase the thickness of the lens, but this is actually a change from distance viewing to close viewing, so the ciliary muscles are relaxing to let you view at a greater distance.
It is possible for a person to determine whether ot not their eyes are focused. This can be determined by visiting an eye doctor, who will look at their eyes through specialized instruments.
If you are touch-typing, your eyes should be on the 3rd to 5th word beyond what you are currently typing.
Anything related to your eyes is best initially checked by a qualified optician. Once your eyes have been checked, the optician may then refer you to a specialist in a hospital, or to your general doctor for treatment.
Convergence of the eyes is achieved by the inward movement of the eyes, controlled by the medial rectus muscles, to focus on a nearby object. This allows both eyes to be directed towards the object, creating a single focused image.
The convergence reflex in the eyes os responsible to keep your eyes aligned and focused on an object. Try moving a pen towards and away from your face; your eyes will follow the object naturally and keep it in focus.
Lights out and pray with your eyes open in the darkness. Best way to speak with God!
Eyes detect light and visual information in the form of colors, shapes, and patterns. Light entering the eyes is focused by the lens onto the retina, where it triggers nerve impulses that are then processed by the brain to create the images we see.

This phrase likely means that the animal's eyes were shining brightly, resembling glowing embers in the darkness of the night. It could suggest that the animal's eyes were intensely focused or perhaps conveyed a sense of danger or mystery.
Because the lens has been focused depending on the available light. if you enter a darker room, your eyes have to re-adjust to allow more light through them.
