Why is “protective eyewear” to be used with the UV black light?
Prolonged and direct exposure to UV light can be harmful to the eyes. This is generally a concern only for professionals who use the very bright Industrial Black Light on a regular basis. With the Consumer model (or mini Black Light), the output is not so bright as to cause a problem in ordinary use, though caution should be exercised in never looking directly into the light. As far as protective eyewear goes, most modern prescription glasses include a UV coating. Inexpensive safety glasses from the hardware or home-improvement store generally include a UV coating –check the product labeling to be sure.
