One-Day Contact Lenses should be comfortable immediately upon

placement on the eye. Care should be taken to ensure the lens is free of

foreign particles such as lint, and is not inverted prior to placement on the

eye. Reex tearing due to an uncomfortable lens may cause the lens to

stop moving and give the appearance of a tight t.

Allow the lenses to settle on the eyes for approximately 5 to 10 minutes.

This allows time for the patient to adapt to the lenses and time for the lens

to equilibrate.
