On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
The 'object lens' in a compound microscope is closest to the object being examined.
The term for an eye in which the natural lens has been replaced with an intraocular lens is "pseudophakic eye."
The lens you look through in a telescope, binocular, or microscope is called the eyepiece. It is the lens closest to your eye that magnifies the image produced by the objective lens.
The objective lens of a compound microscope is the lens closest to the object being examined. It is responsible for magnifying the image of the specimen.
The lens closest to the eye in a microscope is called the eyepiece or ocular lens. It is where the viewer looks through to observe the magnified image of the specimen being examined.

The eyepiece in a microscope is the lens that you look through to observe the specimen on the slide. It magnifies the image created by the objective lens, which is the lens closest to the specimen. The eyepiece typically provides additional magnification to allow for detailed examination of the specimen.

A crystalline lens is the lens in the human eye.

The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
