| umls-concept:C0181752 | skos:definition | UMD: Masks designed to cover both eyes with an opaque material that does not allow the passage of light. These masks typically consist of an external covering made of plastic or other appropriate material and a padded liner (e.g., foam, gauze); masks may include shielding for visible, infrared, or invisible light between the external covering and the liner. Eye masks may be attached to the head using a cap, straps, and/or adhesives; some masks also include nasal cushioning. Eye masks are usually disposable devices that are intended to facilitate rest or sleeping in illuminated environments and/or at home; dedicated masks used during phototherapy treatments for neonates are also available. | lld:umls |
