The purpose of this study is to examine the short-term protective effect of Ultra-Violet filtering contact lenses on macular pigment ocular density.

Inclusion Criteria:

• The subject is an adapted soft contact lens wearer
• The subject's spherical error equivalent (Best Sphere corrected for back vertex distance) must be from -0.50 diopters (D) to -6.00D or from +0.50D to +4.00D in each eye
• The subject must have a refractive astigmatism in each eye of -0.75D or less
• The subject must have a best corrected visual acuity of 6/9 or better in each eye.
• The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol
• The subject must read and sign the statement of informed consent
• The subject must be at least 18 years of age

Exclusion Criteria:

• Systemic or ocular allergies which might interfere with contact lens wear
• Systemic disease which might interfere with contact lens wear
• Ocular disease which might interfere with contact lens wear
• Grade 3 or 4 Slit Lamp Findings
• Greater than 0.1 difference in macular pigment optical density (MPOD) findings between right and left eye at baseline visit
• On changing stable medication or taking any medication known to affect tear film
• Active ocular surface pathology
• Use ocular medication
• Had had any anterior ocular surgery or other ocular surgery or injury within 8 weeks immediately prior to enrollment for this study
