Contact lenses should feel comfortable during normal wear. If your lenses become painful, cause redness, blurry vision, excessive tearing, or sensitivity to light, remove them immediately.Discomfort may be caused by a damaged lens, dry eye disease, an eye infection, allergies, an improper lens fit, or debris trapped beneath the lens. Continuing to wear painful contact lenses can increase the risk of corneal injury or infection.If your symptoms persist after removing your lenses, or if you experience significant pain, worsening redness, discharge, or decreased vision, contact your eye care provider as soon as possible. Prompt evaluation and treatment can help prevent more serious complications and protect your vision.
