It is a lens made up of two miscible fluid of different refractive index:
one a electrically conducting aqueous solution and the other an electrically non-conducting oil. It has no moving parts . Now it is used in phone ,cameras etc.
This works on the principle of mimics the action of the human eye using a fluid lens that alters its focal length by changing its shape.This also overcomes the fixed-focus disadvantages of present lenses

What is fluid focal lens?
A "fluid focal lens" is a type of lens that uses a fluid to change the focal intensity of the lens, instead of having to electronics to adjust a fixed-focal-point lens to adjust the focus when you're using it for applications like eyeglasses or digital cameras and may save space.
How do you focus your Nikon D5000 camera when filming?
If you have an AF, or auto-focus lens (like the kit 18-55mm lens) you can focus your lens prior to filming, but cannot auto-focus while filming. To manually focus, switch the switch on the side of your lens to 'M' for manual. To focus, turn the outer focus ring on the lens until your subject matter is clear.

A CPU camera lens has electrical contacts on it. This means that it also has the auto focus option, which is where the lens will focus itself.

What is the function of the lens in the eyepeice?

What is the correct microscope procedures?
Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
What is the medical term for normal adjustment of the lens to bring an object into focus?
The medical term for normal adjustment of the lens to bring an object into focus is "accommodation." This process involves the changing of the lens shape to focus on objects at different distances.
What type of lens is the lens of your eye?
The lens in the human eye is a convex lens, but it is flexible and when it is acted on by the ciliary muscle around it, the lens can be "flattened" to change the focus, or, when the muscle is relaxed, the lens can assume a more spherical shape. This is at the heart of the ability of the eye to focus on objects nearer or farther away.
What structure changes its shape to focus light at the back of the eye?
The lens of the eye also called the crystalline lens.
How do you improve resolution of microscope?
Focus the lens.
