There isn't a single scientific name for "sight" itself. Instead, the scientific study of sight focuses on:

* Vision: This is the general term for the ability to see.

* Ophthalmology: This is the branch of medicine that deals with the eye and its diseases.

* Optometry: This is the profession that focuses on the health of the eyes and the correction of vision problems.

* Visual Perception: This refers to the process of interpreting and understanding what we see.

So, while there isn't a single word for "sight" in science, these terms represent the different aspects of this complex process.
