Dr. Mandell highlights that while double concave lenses are primarily used for their elongating and diverging properties, the materials they're made from can sometimes lead to unexpected outcomes. "Many users assume that any lens material is safe for close contact, but that's not always the case. Low-quality plastic lenses can shatter, posing a significant risk to users," she explains.
