Brief Summary:
The purpose of this trial is to compare the functional visual performance of Precision Profile Multifocal (MF) contact lenses to Progressive Addition Lens (PAL) spectacles in a presbyopic population.

Condition or disease Intervention/treatment Phase
Presbyopia Device: Multifocal soft contact lenses Other: Progressive addition lens spectacles Not Applicable

Detailed Description:
Habitual contact lens wearers will be randomized to one of three commercially available MF contact lenses. Progressive addition lens wearers will wear their habitual spectacles. Subjects will be expected to attend 1 or 2 office visits.

Arm Intervention/treatment
Experimental: Multifocal Contact Lenses
Multifocal soft contact lenses according to the subject's prescription and fitted using the Alcon MF fitting guide. Lenses will be worn bilaterally (in both eyes) for up to 3 hours, 1 day only.
Device: Multifocal soft contact lenses
Commercially available contact lenses
Other Names:
  • DAILIES TOTAL1® Multifocal contact lenses
  • DAILIES® AquaComfort Plus® Multifocal contact lenses
  • AIR OPTIX® plus HydraGlyde® Multifocal contact lenses

Active Comparator: PAL Spectacles
Progressive addition lens spectacles according to the subject's habitual prescription, with testing up to 3 hours, 1 day only.
Other: Progressive addition lens spectacles
Per subject's habitual prescription
Other Name: PAL

Primary Outcome Measures :
  1. Average transition time during alternate distance (4 m) and intermediate (80 cm) viewing [ Time Frame: Time to Event (Day 1, up to 3 hours) ]
    The subject will be asked to read text at distance (4 meters from the subject), followed immediately by text at intermediate (80 centimeters from the subject) and start reading when the text becomes clear. The interval (milliseconds) between when the subject stops reading the distance text and starts reading the text at intermediate is defined as the transition time.
