The vitreous and lens primarily absorb UV wavelength ranging from _______ to ________ nm?

The vitreous body and the lens of the eye are effective in absorbing ultraviolet (UV) light, particularly within the range of 300 to 350 nm. This absorption is crucial for protecting the retina and other sensitive structures in the eye from the harmful effects of UV radiation, which can lead to conditions such as cataracts and photochemical damage.

In this specific wavelength range, the lens becomes increasingly absorbent as wavelengths decrease below 350 nm, providing a protective mechanism against potential UV-induced damage. By absorbing these UV wavelengths, the lens and vitreous help to prevent the transmission of light that can cause photochemical injury to the retinal layers, ultimately helping to maintain ocular health.

The selected range of 300 to 350 nm represents the part of the UV spectrum predominantly filtered out by the eye's natural structures, emphasizing the critical role they play in visual and overall ocular health.
