Background: International Journal of Innovative Science and Research Technology https://doi.org/10.38124/ijisrt/26feb053 ABSTRACT Both sleep & visual functions like accommodation & vergence are very important for students, especially those doing long hours of study or screen time. Many students complain of eye strain, headache or difficulty focusing & we wanted to explore whether sleep quality could be affecting their visual performance.  Objective: To compare vergence and accommodation in students with good and poor sleep & identify the relationship between sleep quality among college students using questionnaire. To check the effect of sleep quality by measuring the NPA, AF, AC/A Ratio, NPC & VF values.  Methodology: First, we took informed consent from the participant. Next, the participant asked to fill out a validated questionnaire which is based on PSQI. This help us to assess their sleep quality. Based on their scores, participant was divided into two groups: a. those with good sleep quality (PSQI score ≤5). b. those with poor sleep quality(PSQI score≥5). After that detailed history taking done and then visual acuity was taken. If VA is less, then refraction was done and then slit lamp examination was taken After that fundus examination was done. Then, we checked the NPA, AF, NPC,VF &AC/A RATIO). After collecting data, the result was done and after that we discussed and at last we did conclusion. Statistical Analysis was done by using Microsoft Excel and R-programmin...
