Study Description

Brief Summary

The prevalence of myopia among high school students in China is as high as 80%-90%. For college students with longer years of education, the majority of myopia and the factors influencing the prevalence of high myopia should be better understood for timely prevention and treatment. This study aims to investigate the prevalence of myopia and education-related influencing factors among college students at Nankai University.

Outcome Measures

Primary Outcome Measures

1. Prevalence of myopia [One day measurement]

   Myopia was defined as an equivalent spherical refraction ≤ -0.50D in either eye

2. Prevalence of high myopia [One day measurement]

   High myopia was defined as an equivalent spherical refraction ≤ -6.00D in either eye

Secondary Outcome Measures

1. Blood pressure [One day measurement]

   Venous blood pressure was measured using a sphygmomanometer, and systolic and diastolic blood pressure results were recorded.

2. Pulse [One day measurement]

   Measure the number of pulses in the quiet state and record the number of beats per minute.
