Yes, of course. Forces don't care how good your eyes are.
microscope
we can see microorganisms, we can see small objects
No, forces are usually observed indirectly through their effects on objects or systems. We cannot visually see forces like gravity, friction, or magnetic forces, but we can witness their impact on the motion or behavior of things around us.
A microscope is used to see small objects by magnifying them through a lens system. These devices are commonly used in scientific research, medicine, and various other fields to observe objects at a microscopic level.
What we can see is the reflection of light from other objects. Certain substances act as a filter, they absorb and repel certain frequencies of the Electro-magnetic spectrum to give colour etc. When there is no light source, there is no light for objects to reflect, so we can't see them. Our eyes can see only a very small fraction of the Electromagnetic spectrum.
The human eye can typically see objects as small as 0.1 millimeters, which is about the width of a human hair.
Most objects have a force of gravity acting on them that is proportional to their mass and the distance between them. If objects are far apart or have small masses, the force of gravity might not be strong enough to overcome other forces acting on them, like electromagnetic forces or internal forces within the objects themselves. This is why we don't see everyday objects being pulled towards each other due to their masses.
A stethoscope
so that you can see objects that are too small to be seen by the naked eye
Microscope
That is gravity. See: http://en.wikipedia.org/wiki/Gravity
A microscope is used to see micro objects clearly. It magnifies small objects that are difficult to see with the naked eye, allowing for detailed observation and examination.
