Women Prefer Contact Lens Under-Correction
Clinic-based study suggests sex differences in preferred contact lens under-correction during presbyopia management
A retrospective study published in Clinical Optometry analyzed contact lens prescriptions of over 3,000 patients aged 20 to 79 in Kanagawa, Japan, revealing that women aged 40 to 59 preferred greater under-correction of contact lens power than men of the same age, despite similar near addition requirements. The study noted pronounced sex differences in lens power preferences, with women exhibiting higher under-correction. Factors influencing under-correction varied by sex, and limitations of the study included its retrospective nature and reliance on data from a single clinic.
1. Women aged 40-59 prefer greater under-correction in contact lenses than men. 2. Study involved over 3,000 patients from a single clinic. 3. Mean Δ lens power was 0.41 diopters for women vs. 0.34 for men. 4. Factors associated with under-correction differ by sex. 5. Study limitations include a lack of objective measurement and reliance on retrospective data.
