UV-blocking contract lenses are an effective means of helping to limit exposure to harmful rays, but do not offer complete protection, one expert has warned.
Dr Karl Citek, chair of the Commission on Ophthalmic Standards at the American Optometric Association, said that for those in need of vision correction, a "significant measure" of UV protection can be achieved with a combination of UV-blocking contact lenses and other precautions.
However, he added: "Although UV-blocking contact lenses provide important added protection for patients, they should not be viewed as a stand-alone solution."
The expert noted that such lenses should always be worn in conjunction with high-quality UV-blocking sunglasses and a wide-brimmed hat for maximum UV protection for the eyes.
Recently, Karen Walsh, professional affairs manager at Johnson & Johnson Vision Care, noted that UV-blocking contact lenses have been proven to protect the eyes from sun damage, because they cover the entire cornea and limbus, protecting against the peripheral light focusing effect.
