An excerpt from Wikipedia

Photo-degradation is the alteration of materials by light.

Typically, the term refers to the combined action of sunlight and air.

Photo-degradation is usually oxidation and hydrolysis but does not apply to how materials may be aged or degraded via Infrared light or heat.

This basically says that light will break down the material into smaller and smaller pieces, in some cases the pieces are not visible with the naked eye.
