Optical scanning is primarily used for inputting data from barcodes into a computer system, which is essential in various settings such as retail, inventory management, and logistics. This process involves using a scanner to read the patterns of light reflected from the barcode, converting it into a digital format that can be processed by computer systems. The efficient and accurate transfer of this data greatly enhances inventory tracking, reduces human error, and speeds up transactions.

Understanding the other options provides clarity on why they do not suit the definition of optical scanning. Enhancing the visual appearance of documents relates more to graphic design or printing techniques rather than data input. Physically counting inventory items engages manual processes rather than digital scanning technologies, while scanning the overall health of patients typically involves medical imaging technologies, such as MRI or CT scans, unrelated to optical scanning in the context of data input. Thus, the use of optical scanning is distinctly focused on the capture of data from barcodes.
