Bifocals offer only two lens strengths (and trifocals, three). So sometimes objects at a semi-close distance can be out of focus. Progressive lenses offer a much wider gradient of viewing distances. Progressive lenses may take a few extra days to get used to.

The main difference between simple and compound tissue is that simple tissue is made up of only one type of cells whereas compound tissue is made up of several types of cells. Further, the simple tissue consists of parenchyma, collenchyma, and sclerenchyma while compound tissue consists of xylem and phloem.

Best Answer: The difference is a simple microscope has one lens where a compound microscope has an objective lens and an eyepiece with a longer focal length. a simple microscope only has one type of lens, usually objective lens, but a compound microscope had both objective lens and ocular lens.

The difference between the receptive fields and the characteristics of simple and complex cells is the hierarchical convergent nature of visual processing. Complex cells receive inputs from a number of simple cells. ... The manner through which simple cells are able to make up complex cells is not fully understood.

Differences between Sheep eye and Human eye Sheep eye has tapectum lucidum that is a layer f tissues causing reflection of light. This is lacking in human eye. Human eye has six muscles for eye movement whereas sheep have only 4 muscles to mover their eyes.

A biological or compound microscope (pictured left) might have a binocular (two eyepieces) OR monocular head, and magnifies at a much higher power than a stereoscope. A compound microscope is designed for viewing small cells, or thin sections of organs or tissues placed on a glass mounting slide.

The insect compound eye is like having lots of little eyes looking in different directions, but each little eye doesn't see very well. The human eye can swivel, but it only looks in one direction at any given moment.

Progressives. Standard progressives are multi-focal lenses with three viewing areas: distance-, intermediate-, and near-vision. ... Many people confuse the terms “bifocal” or “trifocal” with “progressive,” but it is key to remember that bifocals and trifocals have a visible line in the lens, while progressives do not.

The simple / compound distinction is based on on duct shape. A simple gland has an unbranched duct (or no duct at all). There is only a single secretory unit (acinus or tubule). ... A compound gland has a branching duct.

Diplopia, or double vision, is a condition where a single object is seen in duplicate. Double and blurred vision are often thought to be the same, but they are not. In blurred vision, a single image seen by one eye appears unclear.

Compound microscopes have the advantage that they allow you to magnify an object to a much greater extent (up to 1000x) compared to a stereo microscope (max. about 300x). Compound microscopes also have disadvantages. Not every object is suitable for observation.
