Assertion (A) is true but reason (R) is false. The light from a distant object arriving at the eye lens may get converged at a point in front of the retina. This type of defect is called near-sightedness or myopia. This means that the eye is producing too much convergence in the incident beam.

Assertion and Reasoning
Assertion: Light from a distant object arriving at the eye lens may get converged at a point in front of the retina.
Reasoning: The eye is producing too much divergence in the incident beam.
Explanation:
The eye is an optical instrument that produces a focused image of the visual world on the retina. The retina is a light-sensitive tissue located at the back of the eye that contains photoreceptor cells called rods and cones. The rods and cones convert light energy into electrical signals that are sent to the brain for interpretation.
When light from a distant object enters the eye, it passes through the cornea, the aqueous humor, the lens, and the vitreous humor before reaching the retina. The lens of the eye is responsible for focusing the light onto the retina. However, in some cases, the light from a distant object may not be focused properly on the retina, and instead, it may be focused in front of the retina.
This happens when the refractive power of the eye is too high, causing the light to converge too much. This condition is known as myopia or nearsightedness. People with myopia have trouble seeing distant objects clearly, as the light from these objects focuses in front of the retina, rather than on it.
The Reasoning given in the statement is not correct because the eye is not producing too much divergence in the incident beam. In fact, it is the opposite. The eye is producing too much convergence, causing the light to focus in front of the retina.
Conclusion:
Hence, the correct answer is option (c) Assertion (A) is true, but Reasoning (R) is false.
