The objective of this study is to determine if multifocal contact lenses affect accommodation and/or binocular vision when worn by pediatric patients. This will be accomplished through subjective and objective accommodative and binocular experiments in children wearing single vision and multifocal soft contact lenses.

Inclusion Criteria:

• 7 to 15 years of age
• Refractive error between -1.00 and -8.00 D sphere, with less than or equal to 1.00 D astigmatism
• Corrected visual acuity of 20/25 or better in each eye

Exclusion Criteria:

• Ocular or systemic disease known to affect accommodation or vision
• Convergence or accommodative disorder, or any strabismus
• Use of oral or topical medications known to affect accommodation

The study population includes children and teens that are recruited from the University Eye Center at SUNY College of Optometry and from the greater New York City area.
