The purpose of this study is to assess the safety and efficacy of FID 123320 Ophthalmic Solution compared to Vehicle for relieving redness of the eye due to minor eye irritations in pediatric and adult populations.

This study will enroll 2 cohorts: An adult cohort (Subjects 18 years and older of age from any race and ethnicity) and a pediatric cohort (Subjects 5 - 17 years of age from any race and ethnicity).

The primary endpoint will be collected at Day 1 (Visit 2).

The expected study duration for each subject is approximately 10 weeks with approximately 8 weeks (56 days) of investigational product (IP) exposure.
