The insights afforded by this work inspire me to work on the manufacture of superior handheld magnifiers, devices which are somewhat difficult to make but no more so than the lenses I already need to wear. The goal would be to recreate tools that already exist, if in a more accessible form. My first attempts were with lenses manufactured in Egypt, and I have lately found ways to grind French glass to similar specifications. I can imagine that, someday, perhaps in our lifetimes, even greater degrees of perfection and thus magnification will become available, which could prove a boon to medical studies and those in the natural sciences. In the meantime, we can make better opera glasses and handheld magnifiers, which, it occurs to me, might be of use to examine evidence in criminal investigations ... indeed, when I perfect such a magnifier, I will send one off to Dr. Pekel for use in his work. Though not sturdy enough to survive all the perils of warfare, they will be sufficiently well made to compare to the telescope in durability and will have a similar, if opposite, use, not the making of far things near but the making of near things larger and, one hopes, clearer.
Bacon indicates some debt to Alhazen and Ibn-Sahl. It appears that such lenses may have been in use for centuries already, and it is only the difficulty in crafting them and the associated cost that keeps them from being a part of every student's basic equipment.
