N/A Condition 1: Refractive errors. Condition 2: sleep quality. The intervention consists of optical correction of participants’ refractive errors using appropriate spectacle lenses. Following a complete optometric examination, a standard and up-to-date prescription is provided for each participant. Participants are instructed to wear the prescribed spectacles for at least eight hours per day over a four-week period. Visual parameters, sleep quality, and higher-order optical aberrations are assessed before and after the intervention.. No - There is not a plan to make this available Justification or reason for not sharing IPD is "There is no further information"

Not wearing glasses in the past 6 months or current prescription is inappropriate Written consent to participate in the study Having eyes (asthenopia) Not having presbyopic qualities and having perfect nearsightedness 30 years 40 years Both Any active anterior and posterior segment disease of the eye History of eye surgery (including refractive surgery, cataract surgery, corneal transplantation, ring, cross-linking, etc.) History of eye trauma Accommodation and vergence disorders, strabismus, amblyopia or history of related treatments in the past Systemic diseases affecting eye refractive errors (such as systemic autoimmune diseases, thyroid diseases, diabetes, etc.) Psychiatric disorders or use of psychotropic drugs Use of drugs that affect sleep or vision such as benzodiazepines, hypnotics, ophthalmic drugs with CNS effects in order to reduce confounding factors in examining the effect of uncorrected refractive errors on sleep quality. Wearing any type of contact lenses in the last month Regular coffee and caffeinated beverages People with stressful, shift or hourly jobs Working in bright and noisy environments H52 G47 Disorders of refraction and accommodation Sleep disorders Treatment - Other The intervention consists of optical correction of participants’ refractive errors using appropriate spectacle lenses. Following a complete optometric examination, a standard and up-to-date prescription is provided for each participant. Participants are instructed to wear the prescribed spectacles for at least eight hours per day over a four-week period. Visual parameters, sleep quality, and higher-order optical aberrations are assessed before and after the intervention. Sleep quality. Timepoint: The primary outcome measures include baseline (before optical correction) and 4 weeks after optical correction and continued use of glasses. At these two time points, sleep quality is measured and compared. Method of measurement: Sleep quality is measured using the Pittsburgh Sleep Quality Questionnaire. High-order optical aberration. Timepoint: The primary outcome measures include baseline (before optical correction) and 4 weeks after optical correction and continued use of glasses. At these two time points, higher-order optical aberrations are measured and compared. Method of measurement: Higher-order optical aberrations are measured using a pentacam device based on Zernike coefficients and the root mean square value of the aberrations is recorded.
