Final answer:
The average tear osmolarity is about 308 mOsmol/L, while the osmolarity of the cornea is around 320 mOsmol/L. This difference in osmolarity helps maintain the stability and hydration of the cornea.
Step-by-step explanation:
The average tear osmolarity is about 308 mOsmol/L. The tear film on the cornea has a higher osmolarity compared to the tear layer. The osmolarity of the cornea is around 320 mOsmol/L. This difference in osmolarity helps to maintain the stability and hydration of the cornea.
