According to various embodiments, a medical sensor assembly may include compressible light barriers configured to prevent undesired light from being detected. The compressible light barriers may protrude from the surface of the sensor. However, when applied to the tissue, the compressible light barriers may be compressed to the point of being substantially flush with the tissue.
