Which statement about soft contact lenses is true?

Explanation:
Soft contact lenses are designed to be comfortable and breathable for the eye. Their softness comes from flexible hydrogel or silicone hydrogel polymers, which mold gently to the eye’s surface and move with blinking. This comfort is paired with oxygen permeability, especially in silicone hydrogel lenses, which lets more oxygen reach the cornea and supports healthy corneal metabolism during wear. Because these characteristics—softness for comfort and good oxygen transmission—are defining features of typical soft lenses, the statement about soft contact lenses being true aligns with real-world lens performance. While individual experience can vary, the general truth about their comfort and oxygen permeability holds across standard products.
