The Bower Bird
.png)
( A male satin Bower bird ) TOTALLY random stuff I've collected on the web and doesn't have a place in the jazz guitar, ukulele or main publishing pages on the site.
I remember seeing a this bird on TV years ago. And, it stuck with me. Some of the strangest things get into ones's long term memory. Good for Trivial Pursuit but not much more.
Just like the Bower bird that collects a variety of objects like shells, leaves, flowers, feathers, stones, berries, and even discarded plastic items. A bower's U-shaped nest, a structure of sticks and leaves can include hundreds of these objects. The bird will spend hours carefully sorting and arranging his collection, with each thing in a specific place.
All of this to attract the female Bower bird. The things we do!!!

Adjustable Focus Eyeglasses are prescription eyeglasses with an adjustable focal length. They compensate for refractive errors (such as presbyopia) by providing variable focusing, allowing users to adjust them for desired distance or prescription, or both.
Current Bifocals and progressive lenses are static, in that the user has to change their eye position to look through the portion of the lens with the focal power corresponding to the distance of the object. This usually means looking through the top of the lens for distant objects and down through the bottom of the lens for near objects. Adjustable focus eyeglasses have one focal length, but it is variable without having to change where one is looking.
Possible uses for such glasses are to provide cheap glasses for 3rd world countries, or to accommodate for presbyopia.

Listing Info
( from listing's site ) - Superfocus glasses give you the ability to focus the entire lens to any distance. You set the focus you need, when you need it.
Read a book, work on the computer, watch television, replace a faucet under the sink or shop for groceries. Distance and height don't matter. Your vision is always crystal clear at whatever distance you need to focus on, whether you are looking up or down or out of the corner of your eyes.
When Dr. Stephen Kurtin reached the age when his eyes could no longer focus on nearby objects, he found that none of the then-available “answers” satisfied him. Bifocals, reading glasses, swapping multiple glasses, and progressive lenses all had major flaws. A successful inventor with over 30 patents and a Ph.D. in Applied Physics from Caltech to his credit, Dr. Kurtin set out to develop a better solution.
