This is a low vision reading loupe. Easy and cheap DIY loupe.
People with low vision, need something to magnify the letters to be able to read it.
With this, all you have to do is place it over the text and read.
PD: English is not my native language, sorry.
Step 1: Saw the Bottom of the Lightbulb
Remember to wear protective gloves and glasses!!!
Step 2: Remove the Inside Parts of the Lightbulb
Step 3: Fill the Lightbulb With Water
Step 4: Close the Lightbulb With Epoxy Putty
Don't leave air inside the lightbulb.
Is hard to take all the air, I fill it with water and do the close underwater.
There is no problem putting the epoxy putty under the water.
Once I have it close, I take it out and let it dry.
