Evaluating Contact Lens Optics

Evaluating Contact Lens Optics

This study will evaluate changes in refractive error and visual performance between a single vision soft contact lens and multifocal soft contact lens

Inclusion Criteria:

• Able to read and understand the informed consent document
• 18 to 39 years of age (inclusive)
• Best corrected visual acuity of 20/25 or better in the right eye
• Refractive error from -1.00D to -6.00D with astigmatism less than or equal to -1.00D in the right eye (corneal plane)

Exclusion Criteria:

• Any ocular or systemic conditions affecting vision, refraction, or the ability to wear a soft contact lens
• History of ocular trauma or surgery causing abnormal or distorted vision
• Current Rigid Gas Permeable (RGP) contact lens wearers
• Unwilling to have contact lens fit photographed
• Pregnant and/or lactating females, by self-report
