Orbital Bone Anatomy
Seven bones, one socket, the thinnest skin on the human body. The orbital bone sits under approximately 0.5mm of tissue at the tear trough — compared to 2–3mm on the cheek. That thinness is why the periorbital region ages first, and why it responds to photons better than any other facial region. The 888-LENS is engineered for this anatomy specifically, not adapted from full-face hardware.
About this topic
The orbital bone (os orbitae) is the bony socket of the skull that houses and protects the eye, formed by seven cranial bones: the frontal, zygomatic, maxillary, lacrimal, ethmoid, sphenoid, and palatine. The periorbital region encompasses the infraorbital rim, lateral orbital rim, tear trough (nasojugal groove), and lateral canthus. The skin overlying these structures is the thinnest on the human body, measuring approximately 0.5mm at the tear trough compared to 2–3mm on the cheek and forehead. This thin tissue profile creates unique opportunities for phototherapy: photons encounter minimal attenuation before reaching dermal fibroblasts (200–500 microns) and capillary beds (300–800 microns). The six extraocular muscles controlling each eye perform approximately 100,000 movements daily.
