Final answer:
There are no drugs that directly turn the sclera blue. Certain medical conditions, such as osteogenesis imperfecta and Wilson disease, can cause a bluish discoloration of the sclera.
Step-by-step explanation:
There are no drugs that directly turn the sclera blue. The sclera is the white part of the eyes and it is typically white in color. However, certain medical conditions can cause a bluish discoloration of the sclera.
One example is a condition called osteogenesis imperfecta, also known as brittle bone disease. In this condition, the collagen in the body is defective, which can result in weak and brittle bones as well as a blue tint to the sclera.
Another example is a rare condition called Wilson disease, which is a genetic disorder that causes copper to accumulate in the body. This buildup of copper can lead to various symptoms, including a bluish-green discoloration of the sclera.
