What does the supenser ligament in the eye do?
The suspension ligament holds the lens in a position and changes the focus so you can see everything clearly and properly
How do your eyes adjust for seeing objects at different distance from you?
The muscles in the eyeball pull the shape of the lens (the black bit !) to change the focus of the eye. This takes place very quickly, so you hardly notice it.
How far does light travel from a flashlight during the day?
The distance light from a flashlight can travel during the day is technically unlimited in a vacuum, but in practical terms, it is significantly reduced due to sunlight and atmospheric scattering. During daylight, the bright ambient light can overpower the flashlight's beam, making it difficult to see beyond a few meters. In clear conditions, the beam may still travel several kilometers, but its visibility diminishes rapidly in the presence of sunlight.
