The red reflex is caused by the reflection of light from the retina in the eye. When a light source, such as an ophthalmoscope, is directed into the eye, it illuminates the fundus, and the healthy retina reflects this light back, appearing red due to the rich vascularization and the presence of choroidal blood vessels. Any obstruction or abnormalities, such as cataracts or retinal detachments, can disrupt this reflex, indicating potential eye health issues.

What causes the let down reflex?
The let-down reflex is triggered by the hormone oxytocin, released by the pituitary gland in response to the baby suckling at the breast.

Emotional and physical relaxation also play a role in the let-down reflex.
