Eye Lens
The structure in the eye that focuses light onto the retina
Real World Example
Imagine trying to read a book in a dimly lit room, struggling to find the perfect angle under a lamp to clearly see the words. Just as you need to adjust the light and angle to focus on the text, the lens in your eye adjusts to focus light onto your retina for clear vision. In this analogy, the book represents the retina, the lamp is the light entering your eye, and the perfect angle is the adjustment your eye's lens makes to provide clear and focused sight.
