It is generally not visible to the naked eye. Patients may perform appropriate acupressure on specific points during daily life. Gently pressing with the fingertips approximately 2 cm directly below the center of the eyeball can help improve ocular function. This condition results from congenital genetic abnormalities. In red color blindness (protanopia), individuals are unable to distinguish red hues. Patients should pay attention to their daily diet—opting for easily digestible foods while avoiding spicy items.
