ABSTRACT:
The invention presents goggles for preventing a patient from developing exposure keratitis. The goggles include first and second concave eyepieces which form chambers over the patient's eyes. The goggles also include an adjustable nose strap connecting the eyepieces and an adjustable head strap for securing the goggles to the patient. The first and second eyepieces have first and second holes, respectively. A first valve assembly is attached to the first eyepiece for regulating fluid flow through the first hole, and a second valve assembly is attached to the second eyepiece for regulating fluid flow through the second hole. Liquids such as artificial tears are instilled in each chamber through the valve assemblies to keep the patient's eyes moist. The goggles further include first and second cushioning members, preferably air bladders, attached to the rims of the eyepieces. The cushioning members seal the goggles to the patient's face while preventing the patient from developing skin damage or pressure sores.
