Investigators concluded that wearing protective eye glasses while sleeping may be a treatment option for glaucoma, reports Optometry Times.

Study researchers found a significant difference in IOP in the form of an increase from the induction of pressure by a pillow and the relative decrease from wearing protective glasses while simulating sleep.

Of note, with 11 glaucoma patients and 11 controls, the sample size of this study is quite small. More and larger-scale studies are needed to prove that one’s position on a pillow can have such a substantial effect on IOP.
