The lens of the eye plays a critical role in absorbing harmful UV radiation. It contains specific chromophores that effectively filter out a significant portion of UV light, especially UV-B and UV-C rays, which can be damaging to the ocular tissues. This protective function helps to safeguard the retina and other structures in the eye from potential harm that could lead to conditions such as cataracts, macular degeneration, and other UV-related damage.

The cornea does absorb some UV radiation, but its primary role is more about refracting light rather than filtering it. While the retina is sensitive to light and performs the crucial function of capturing and transmitting visual information, it is not inherently a filter for UV light; rather, it is susceptible to damage from excessive UV exposure. The choroid, located behind the retina, is mainly involved in providing nourishment and supporting the retina, but like the retina, it does not serve primarily as a barrier against UV radiation.

Therefore, the lens is specially designed to absorb and thereby protect against UV radiation, making it the correct answer in this context.
