SOURCE: What are bifocal eye glasses used for then what's the purpose of bifocals

Bifocals are eyeglasses with two distinct optical powers. Bifocals are most commonly prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and/or astigmatism. Or are used for people who have a hard time seeing really small prints.

How can I turn off the zeiss Humphrey? only from the shut down button or there is a function from the software?


This is a brand name, not a specific device and model. That said, here is a page describing mode switch in the setup screen using the touch screen for a specific device. I assume a touch screen would have an icon for turning a device off.

How do I determine the open space in a 12" cube


Determine the volume of the cube

Which is calculated by:
length x width x depth

then subtract the volume of the sphere's

Which is calculated by:
Number of spheres multiplied by (4/3) * pi * radius3

To figure out how many sphere's you can fit in the cube

Divide the width of the cube by the diameter of the sphere then cube that number
(try it with a larger diameter sphere for example 6" sphere and sketch it out, you will see why)

0.01" Sphere-Total Volume

12"/0.01"=1200

1200^3 = 1.728 E 9 = Number of sphere's in the cube

1.728 E 9 x (4/3) * pi * 0.0053=904.32 cubic inches

Volume of Cube = 1728

Remaining Volume = 1728-904.32 = 823.68

You should be able to figure out how to do the other one.
