What is the correct handling practice for contact lenses?

The correct handling practice for contact lenses involves washing hands before handling them and following proper cleaning protocols. This is crucial because the hands can carry bacteria and oils that may contaminate the lenses, leading to potential eye infections or discomfort. Proper cleaning techniques include using the recommended solutions for rinsing, disinfecting, and storing contact lenses, ensuring that they remain safe for wear and effective in vision correction.

By adhering to these protocols, wearers minimize risks associated with handling contact lenses, such as corneal ulcers or other complications stemming from poor hygiene. It is important to routinely check the care instructions provided with specific lens types, as different lenses or solutions may have unique handling requirements.

The other options suggest practices that could lead to complications. For example, using any surface to clean contact lenses could introduce harmful contaminants, while storing lenses in water can result in bacterial growth. Additionally, continuing to wear lenses beyond their expiration date can compromise eye health, as the material's integrity may degrade, making them unsafe for use.
