Objective and Subjective Evaluation of Ophthalmic Lenses With Extra Power

Inclusion Criteria: * Subjective report of visual fatigue * Non-presbyopes * Permanent wearers who wear glasses for at least 5 hours a day * Distance refractive error within the range of \[+6.00 to -6.00\]\* (with cylinder in the negative form), * Cylindrical component of the refractive error within the range of 0 to 2 D in both eyes, * Anisometropia ≤ 1.00 D in sperical equivalent, * Visual acuity of +0.10 logMAR or better in each eye with new prescription at distance (high contrast/high luminance), * Distance visual acuity difference ≤0.20 logMAR between right and left eye (high contrast, high luminance) * Near binocular visual acuity of +0.10 logMAR or better with a new prescription (high contrast, high luminance), * Study frame characteristics: Frame B size at least 22 mm Exclusion Criteria: * Vulnerability of the subject, * Participation in another study which might have an influence on vision or interfere with study assessments, * Binocular vision problems, * Known ocular pathology (e.g., age-related macular degeneration, glaucoma…), * Any previous ocular surgery which might have an influence on vision or interfere with study assessments (e.g., iridectomy, refractive surgery…), * Any untreated and/or uncontrolled systemic condition which might have an influence on vision, or interfere with study assessments (e.g., uncontrolled diabetes, uncontrolled high blood pressure…), * Any medical treatment or medication that might have an influence on vision or interfere with study assessments (e.g., antidepressants, drugs with atropinic effects…), * Knowledge/expertise in optometry, ophthalmic lenses, or optics based on past or current professional activity (e.g., optometrists, opticians, ophthalmologists…)
