Dollar Store Reading Glasses Are Not Safety Glasses

I’m of an age that I need reading glasses for close up work. Unfortunately I also need safety glasses in many of the same situations. I know that you can buy magnifying safety glasses, but they are never as inexpensive as the $1.00 reading glasses from the local Dollar Tree.
I am a cautious person (milquetoast) so I thought it would be wise to do a simple test of the shatter resistance of the dollar store reading glasses. On with the science! The dollar store glasses. Poor sap. My RWS Diana Model 45 air rifle. I chose it because I thought I had it sighted in at 10 yards, which I didn’t. With 7.9 grain Crosman pellets at 715 fps, it should hit the glasses with about 9 ft/lbs of energy. 10 yards down the length of my deck. After shooting low a couple of times I finally hit the glasses. First lens. The other lens. Both lenses shattered and I couldn’t even find some of the pieces. As a control I gave my dummy some safety glasses. First shot dented the lens. Second shot knocked the lens out of the frame. I wonder if that’s by design? I remounted the lens and took a third shot. Which eyewear would you rather be sporting when a projectile is coming towards your eye?Imagine that small shard penetrating your eyeball. As you can see the safety glasses deform rather than shattering. 

So I guess I’ll spring for a pair of safety reading glasses, or wear the safety glasses over reading glasses. I won’t be using the readers as safety glasses.

Latest repairs…Dishwasher Slide Rollers, Datadesk Keyboard, Dream Machine.

The rollers on the upper basket of our Kitchenaid dishwasher are crumbling.They are losing teeth… Two lost all the teeth that hold the wheels on. So I tapped 5/16” coarse thread. A 5/16 hex bolt fits the wheel recess perfectly, I just turned down the top and made a screwdriver slot with the bandsaw.And it will work ok for a while longer. Note the zip ties holding the wheel assemblies to the basket, the clips that did so, do no longer. The Datadesk keyboard Max used for a while. It got a bit sticky…gross. Modular design…   Has a separate board for the USB hub and input. I cleaned all teh switches with contact cleaner. It works fine now at my treadmill desk. All I did was take the housing off and clean the switch contacts. Not that exciting.
