Passage Summary: The ozone layer protects animals by blocking certain light, but holes in that layer are letting in rays that can seriously hurt the eyes of many different creatures.

Reasoning: The ozone layer's primary function for land animals is filtering specific light wavelengths, and the presence of holes in this layer poses a significant risk of eye damage across various species.

Analysis: We are looking for a synthesis of the facts regarding light filtration and biological damage. If the ozone layer's job is to filter light and its absence causes eye damage, it is highly probable that the specific wavelengths being let through the holes are the culprits. Look for an answer that connects the lack of filtration to the physical harm mentioned. We don't need to prove the ozone layer is the only thing protecting eyes, just that its specific filtering function is relevant to the damage described.
