Protein and lipid deposits on the contact lens surface were assessed for each eye by the investigator using a biomicroscope, which magnifies the appearance of the contact lens on the wearer's eye. Deposits were graded on a scale of 0 to 4, with 0 being none and 4 being severe.

Each eye was tested individually while the participant read distant charts in normal lighting. Corrected visual acuity was measured using a Snellen chart, which was converted into logMAR units (logarithm of the minimum angle of resolution). A 20/20 Snellen acuity equates to a logMAR acuity of 0.0 and is considered normal distance eyesight. Positive logMAR values indicate poorer vision, and negative values denote better visual acuity.
