Contact lens wearers may have experienced once the discomfort of dust from the contact lenses when they enter your eyes together. Then remove the contact lens from the eye, remove the dust with lens preservative, and try again to avoid discomfort. However, if you continue to feel uncomfortable when wearing contact lenses, you should remove them immediately to prevent other damage. Occasionally, contact lenses may have been slightly distorted by long fingernails and damaged, or contact lenses from the product process may be defective. In such cases, remove the lens immediately to protect your eyes. If you keep wearing it, it can damage your cornea.
