Which of the following is a soft lens disadvantage?

Explanation:
The main concept here is the practical handling drawback of soft lenses due to their flexible, thin material. Soft lenses are comfortable because they mold to the eye, but that same flexibility makes them relatively fragile and easier to tear or crease during insertion, removal, or manipulation. This fragility and the careful technique required for handling is a common disadvantage clinicians note, since mishandling can lead to tears or lenses folding in the eye. Other options don’t fit as a consistent disadvantage. Oxygen delivery to the cornea has improved with modern soft materials, especially silicone hydrogels, and can be comparable to rigid lenses for many wearers, so “lower oxygen to the cornea” isn’t a universal drawback. Cost can vary and isn’t an intrinsic material disadvantage, and improved vision is a benefit, not a drawback.
