Nonetheless, ordinary equipment can be assembled and modified to access the part of the UV spectrum closest to the visible range.

Solar radiation reaching the surface of the attention is targeted and concentrated by the cornea, the clear outermost layer of the eye. The rays that pass through the pupil of the attention are absorbed by the lens of the attention. This UV radiation may cause cataracts in the lens of the eye. Studies show that the UV radiation that reaches the eyes from above, below, and the sides is targeted and focused when it reaches the tissue on the opposite side of the attention. Small tissue elevations, called pingueculea and pterygia, may result.
