Hazards and Risks Associated with using Lamp

Reading the pmt notes, you can see two core practicals require using a lamp. One of them mentions a hazard is "lamp gets hot" which is true and makes sense.

The other paper says "temporary eye damage". Isn't that just bleaching of the rods so they're light-adapted? Or is it actually temporary damage? Can I write this in the exam?

Edit: changed bleaching of eyes to bleaching of rods
