Clinical Report: Women Prefer Contact Lens Under-Correction
Overview
A retrospective study reveals that women aged 40 to 59 years prefer greater under-correction of contact lens power compared to men of the same age, despite similar near addition requirements. The study analyzed data from over 3,000 patients and identified significant sex differences in habitual contact lens prescriptions.
Background
Understanding preferences in contact lens prescriptions is crucial for optimizing visual outcomes, particularly in presbyopic patients. This study highlights the importance of considering sex differences in refractive correction strategies, which may influence patient satisfaction and adherence to contact lens wear. The findings are particularly relevant as the population ages and the prevalence of presbyopia increases.
Data Highlights

Women (40-59)
0.41
1.34
Men (40-59)
0.34
1.35
Key Findings
Women aged 40 to 59 years showed a mean Δ lens power of 0.41 diopters compared to 0.34 diopters in men.
Near addition requirements were similar between sexes, averaging 1.34 diopters for women and 1.35 for men.
Men exhibited greater astigmatic error and anisometropia than women in the same age group.
Ocular surface parameters were generally worse in women, except for the Schirmer test.
Regression analyses indicated different factors associated with under-correction for each sex.
Clinical Implications
Clinicians should consider sex differences when prescribing contact lenses, particularly for women in the 40 to 59 age group who may prefer under-correction to enhance near vision. Tailoring contact lens prescriptions based on these preferences could improve patient satisfaction and visual performance.
Conclusion
The study underscores the significance of sex differences in contact lens power preferences, particularly in middle-aged women. These findings can inform more personalized approaches to presbyopia management.
