Tha comas aig craiceann àbhaisteach solas a ghabhail a-steach gus na h-organan agus na toitean a dhìon anns a 'bhodhaig bho mhilleadh aotrom. Tha comas solais a dhol a-steach do stuth daonna co-cheangailte ri tonn-tonngan aige agus structar clò craiceann. San fharsaingeachd, is ann as giorra an tonn-tonn, an spioradaiche a-steach don chraiceann. Bidh an stuth craiceann a 'gabhail a-steach solas le dìomhaireachd follaiseach. For example, the keratinocytes in the stratum corneum can absorb a large amount of short-wave ultraviolet rays (wavelength is 180~280nm), and the spinous cells in the spinous layer and the melanocytes in the basal layer absorb long-wave ultraviolet rays (wavelength is 320 nm~400nm). Bidh an stuth craiceann a 'gabhail a-steach diofar tonnan de sholas gu eadar-dhealaichte, agus tha a' mhòr-chuid de ghearanan ultraviolet air an glacadh leis an epidermis. Mar a bhios an tonn-tonn a 'meudachadh, ìre ri dholead solas cuideachd ag atharrachadh. A 'toirt a-steach ghathan faisg air an inneal aotrom dearg a dhol a-steach do na sreathan as doimhne den chraiceann, ach tha an craiceann air an glacadh. Tha an tonn fada-uisge (tonn-pàighidh 15 ~ 400μm) a 'dol a-steach gu math dona, agus tha a' mhòr-chuid dheth air a ghabhail a-steach leis an Eleidermis.
