Clouding of contact lenses refers to a reduction in their transparency, resulting in impaired vision for the wearer. This opaqueness can manifest as a hazy or milky appearance on the lens itself. A visible example is when a contact lens that was previously clear becomes noticeably less so, affecting the sharpness of visual acuity.
Maintaining the clarity of contact lenses is crucial for optimal vision correction and ocular health. Clouding can significantly diminish the wearer’s quality of life by causing blurred vision, discomfort, and potentially leading to eye strain or headaches. Historically, advancements in contact lens materials and care solutions have focused on minimizing this issue to enhance user experience and reduce complications.
