Answer 2

➡️☺️ Hey your answer is

Pupil

▶️It's size is controlled by the relaxing and contracting of the iris.

✅When there is high light intensity, the pupil shrinks while it grows in low light intensity. This is to ensure there is enough light for vision without damaging the sensitive retina.

Lens:

▶️A transparent, biconvex, flexible disc behind the iris.

✅Focuses the light onto the retina ( the light sensitive part of the eye).

Thanks ✍️
