Presbyopia if uncorrected causes inability to see and do near work. It is unavoidable as one ages. High school teachers whose work depends much on near work need proper and adequate correction of their presbyopia to increase effectiveness and efficiency.
The aim was to determine the uptake of correction and prescription for presbyopia of presbyopic teachers of public Senior High School (S.H.S.).
Descriptive cross-sectional study.
The study was conducted in 12 public S.H.S. in the Kumasi, with a total sample size of 298. Questionnaire was administered to teachers. Their visual acuity, refraction and ophthalmoscopy were done.
The prevalence of presbyopia among the teachers was 68.1%. Out of the number examined 197(66.1%) were males and 10(33.9%) were females. Amongst the presbyopes 60 did not have presbyopic correction, representing 29.6% of the presbyopes. A total of 52 presbyopic teachers required an add of +2.00DS and this was the highest diopter of correction needed (25.6%). Among those with presbyopic correction 55.5% of them use single vision type of correction whiles the remaining 44.5% use bifocals. Out of the 48% presbyopic teachers who have had their presbyopia corrected before, 6% were not wearing their correction.
The study has demonstrated a relatively higher prevalence of uncorrected presbyopia amongst teachers in public Senior High Schools in the Kumasi Metropolis of 29.6%. Among those with correction 6 % were not using their correction. Proper and adequate correction is needed by presbyopic teachers through screening to ensure their maximum performance.
老花眼若不矫正会导致无法看清近处物体及进行近距离工作。随着年龄增长，这是不可避免的。高中教师的工作很大程度上依赖近距离工作，因此需要对老花眼进行适当且充分的矫正，以提高工作成效和效率。
旨在确定公立高中老花眼教师对老花眼矫正及配镜处方的接受情况。
描述性横断面研究。
研究在库马西的12所公立高中开展，总样本量为298。对教师进行问卷调查，并检查他们的视力、验光和眼底镜检查。
教师中老花眼的患病率为68.1%。在接受检查的人群中，男性有197人（66.1%），女性有10人（33.9%）。在老花眼患者中，60人未进行老花眼矫正，占老花眼患者的29.6%。共有52名老花眼教师需要+2.00DS的附加度数，这是所需矫正的最高屈光度（25.6%）。在进行老花眼矫正的人群中，55.5%使用单焦点矫正方式，其余44.5%使用双焦点矫正方式。在之前已矫正老花眼的48%的教师中，6%未佩戴矫正眼镜。
该研究表明，在库马西市公立高中教师中，未矫正老花眼的患病率相对较高，为29.6%。在已矫正的人群中，6%未使用矫正眼镜。老花眼教师需要通过筛查获得适当且充分的矫正，以确保他们能发挥出最佳工作表现。
