Bulbs that emit UVB and UVC (I’m not sure you can even get the latter easily) are not inexpensive, and do not have a phosphor coating. From what I know about gel coat nail polish, the lights use UVA. I would not look directly at them either. I used some UVB lights for aquarium water sterilization, and you would not want to look directly at them anyway. Just a glance with sunglasses hurts your eyes.

Airing on the side of caution is probably a good idea. I haven't noticed any effects if looking at these lights but I plan on not making it a habit. I'm planning on putting the lures in, then the cover on, then turning the unit on. Never hurts to be careful when it's easy to be and no reason not to be.

I made a UV curing both for my resin 3D printer and I just lined a cardboard box with tin foil and pointed a UV lamp from Amazon in there. Cures my parts great when I put it on a cheap solar powered turn table.  You could use it for lure curing if you just hot glued a coat hanger onto the turntable so it would suspend the lure body.

 

Safetywise I use these uv protective glasses when I am looking at the light. The 405nm wavelength which is what cures this stuff burns out LCDs so I don't want it doing  the same to my retinas. I'm quite fond of them.
