The Hubble Space Telescope is the common name of the satellite with which we are familiar. The satellite contains a large optical telescope which does the observations of space objects. The telescope is a fairly straightforward Ritchey-Chrétien Cassegrain reflector with a primary mirror 2.4 meters (94 inches) in diameter. The telescope images objects with a variety of cameras and spectrographs. See the links for more.
to enable them have free movement in their surrounding environment
HeatCorrection:Cyanobacteria contain chlorophyll which enable them to produce their own food.
The microscope makes transparent objects visible to enable study.
They enable us to grasp objects.
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.

The crystalline lens in human eye is indispensable to perform refraction so as to enable us to see objects clearly.
