Final answer:
Improved vision is not a common side effect of medications for skin disorders, unlike itching, rash, or hair loss.
Step-by-step explanation:
The common side effects of medications for skin disorders include itching, rash, and hair loss. However, improved vision is not a side effect associated with treatments for skin conditions. Medications for skin disorders typically aim to alleviate symptoms like inflammation, irritation, and infection, but they do not affect vision positively. In fact, some medications could potentially lead to adverse effects on vision, although it is not a typical outcome.
