Explain how the pupil changes size in different light conditions and how myopia is corrected.

Here is the completed table and the answer for question (c). | Structure | Darkness | Bright light | | :---------------- | :------------ | :------------ | | Radial muscles | Contract | Relax | | Circular muscles | Relax | Contract | | Size of pupil | Dilates | Constricts | c) Step 1: Understand what myopia is. Myopia, or nearsightedness, occurs when light rays focus in front of the retina, causing distant objects to appear blurry. This can be due to an eyeball that is too long or a lens/cornea that is too curved. Step 2: Determine the type of lens needed for correction. To correct myopia, a lens is needed that will diverge the light rays before they enter the eye, causing them to focus further back, directly on the retina. Step 3: State the correction method. Myopia can be corrected by wearing spectacles or contact lenses that contain concave lenses. Concave lenses are diverging lenses that spread out light rays before they reach the eye, allowing them to focus correctly on the retina. Myopia can be corrected by wearing concave lenses in spectacles or contact lenses. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
