In [[aviation]] training, a '''view-limiting device''' simulates [[instrument meteorological conditions]] (IMC) by restricting a pilot's [[field of view]] only to the [[flight instruments]]. They are worn by pilots who are working toward an [[instrument rating]], which allows a pilot to fly under [[instrument flight rules]] in conditions that do not permit [[visual flight]]. They are also used by instrument-rated pilots while practicing instrument flight to maintain competency.<ref>{{Cite web

Examples include foggles and the IFR hood. Foggles are glasses that have been frosted on the top half of the lenses to simulate [[Fog|foggy]] conditions.

In 2021 The Instrument Conditions Awareness Recognition and Understanding System (ICARUS) Smart View Limiting Device was developed. ICARUS uses Polymer Dispersed Liquid Crystal Film or [[Smart glass|Smart Glass]] to electronically change between simulated [[Visual meteorological conditions|VMC]] and [[Instrument meteorological conditions|IMC]] to aid pilot training. This capability allows pilots to actually train for [[Continued VFR into IMC|VFR into IMC]] which often leads to [[spatial disorientation]].
