Why is it important to know if the client wears contact lenses or glasses for make up treatment?

Knowing if a client wears contact lenses or glasses is crucial for makeup treatment as it influences product choice and application techniques. For contact lens wearers, it's essential to ensure that products are safe for sensitive eyes and won't cause irritation. Meanwhile, glasses may require specific makeup strategies to enhance the eyes without causing glare or obscuring features. Understanding these factors helps create a tailored and comfortable experience for the client.
