Ebbnivs Large Magnifying Glass

My dad never needed a magnifying glass because he had bifocals on his actual glasses. After cataract surgery he doesn't need to wear his glasses anymore to see distance. However he needs glasses to see how close. The doctor told us not to use his old glasses for reading because that would mess with his brains ability to learn how to use the new lenses he has in his eyes. During the transition time I pick this up for him and he's able to read his paper, magazines and bills. I do really like that it has a light on it however there is what is stated in the description as a UV light. I don't understand the purpose of that. My issue is that one click turns the light on, a second click turns the light off but the UV light on and the third click turn everything off. My father forgets the third click so he ends up leaving it with the UV light on that runs down the AAA batteries inside. Other than that issue it's a nice large magnifying glass that is light and easy to hold.
