"Bi-ocular" typically refers to a type of binocular vision where both eyes work together to focus on an object. This allows for greater depth perception and improved visual acuity compared to using just one eye.
The word Biocular means two eyes in Latin language.
All primates - humans, apes, chimpanzees etc
The term "15 x 80 biocular" typically refers to binoculars that have a magnification of 15x and an objective lens diameter of 80mm. This means that objects viewed through these binoculars will appear 15 times closer than they do to the naked eye, and the larger lens diameter allows for better light transmission, making them suitable for low-light conditions. These specifications make such binoculars ideal for activities like birdwatching or stargazing.
The eyepiece of a microscope is called the ocular lens. It is the lens closest to the eye of the viewer and is responsible for magnifying the image produced by the objective lens. The ocular lens typically has a magnification power of 10x, and when combined with the magnification power of the objective lens, it determines the total magnification of the microscope.
