About a month ago I purchased a magnifying light off craigslist. My eyes are bad and I needed help.
This thing is fantastic and I recommend them to even the good-sighted people.
It has really help with getting sheds started, getting retained eye caps off and just general inspection of my snakes.
I was lucky enough to find a high dollar one for little money ($20.00) This is a dermatology grade light.
Just a suggestion.
