Sight glasses are transparent industrial glass that are used for observing levels of liquids or gases inside of a pipe, tank, or boiler. This is critical as it allows plant managers or engineers to look inside their systems without disrupting the flow of operations.

Often referred to as viewing glasses, they offer you a way to see the levels of liquids or gases that are traveling through a critical point of your design, monitor pressure changes, and virtually anything else that sight glass windows could allow you to do.

Magnifiers won't damage your eyes, but you may feel your eyes get tired if you're using them constantly. If so, there are ways to use magnifiers for your low vision that won't negatively impact your quality of life and help make you and your eyes feel better.
