Women Prefer Contact Lens Under-Correction

Clinic-based study suggests sex differences in preferred contact lens under-correction during presbyopia management

1

Women aged 40 to 59 years preferred greater under-correction of contact lens power than men of the same age.
2

The study analyzed refractive data from 3,082 patients aged 20 to 79 years attending an eye clinic in Kanagawa, Japan.
3

In the 40 to 59 year group, women had a mean Δ lens power of 0.41 diopters, compared to 0.34 diopters in men.
4

Regression analyses showed different factors associated with under-correction for women and men, with age not significantly influencing results.
5

The study concluded that under-correction is used to maintain distance vision while improving near vision during daily activities.
