They are reading glasses with standard prescription.
I buy expensive Kodak lenses that last me MANY years, and My prescription didn't change.
They do break and I move the lense to a new frame.
Since 2015 I have been using the same frame. And changed my lense once.
However, I do take care of my lenses so it won't scratch.
I mainly started this system because I just don't like change, it would make me go crazy or something. I am a bit cuckoo
Cuckoo out
Edit: cuckoo back, i have this soap dispenser that dispenses soap foamy.you fill it with 1 part liquid soap and 2 or 3 part water.
I use a tissue LIKE A BRUSH to brush away the dust, this way the dust ln the lense won't scratch it. Then use that mild foam soap to wash the lense and then dry it by DABBING tissue on the lense.
When you failed life and you feel ashamed to spend your sugar daddies money, you find ways to make things last.
Also, back hurts, not the hole area, the lower spine part. My legs hurt too... is that too much information? Well I think it is
