The cornea is the part of the human eye that bends light rays the most when focused on a distant object.
the pupil that is why it gets smaller in the light
An eye is a complex structure and essentially all parts of the eye are required for vision to occur. However the part of the eye which detects the focused (by the lens) light image is the retina.
The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.

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.
Astigmatism is an eye defect characterized by clear vision in one dimension, but focused in a different dimension. It occurs when the cornea or lens of the eye is not perfectly spherical, causing light to be focused unevenly. This can result in blurred vision at different distances.
A laser is a beam of very strong and focused light. It is possible for this light to damage the retina of your eye permanently, and you will lose all or part of your vision.
If something "catches" your eye, it has snagged your attention. You are focused on that thing for whatever reason.
The iris is the coloured part of the eye.
As light enters the eye, it passes through the cornea, the aqueous humor, the lens, and finally reaches the retina. These structures help to focus and transmit the incoming light to the photoreceptor cells in the retina where the visual signals are initiated.
When light enters your eye, it is focused by the cornea and the lens onto the retina at the back of the eye. The lens adjusts its shape to help focus the light onto the retina, where it is converted into neural signals that are sent to the brain for processing.
