Subject selection is based on a history of wearing one of two types of contact lenses for at least five years. Age-matching subjects into 4 age-brackets will be attempted with a target of five subjects in each age bracket among the two types of lenses.
Exclusion Criteria:
Subjects who have worn a soft contact lens without UV protection for the past five years or more.
Device: No Intervention
Subjects who have worn a soft contact lens with UV protection for the last 5 years or more.
Device: No Intervention

Macular Pigment Optical Density (MPOD) after 5 years of contact lens wear
The MPOD will be assessed at a single visit will be compared between wearers of contact lenses with UV protection and those wearers of lenses without UV protection, based on their 5 year wear history.
Time frame: Approximately 40 minutes
Amplitude of Accommodation after 5 years of contact lens wear
Measured with autorefractor at a single visit and will be compared between wearers of contact lenses with UV protection and those wearers of lenses without UV protection, based on their 5 year wear history.
Time frame: Approximately 40 minutes
