Eligibility
Inclusion criteria
Inclusion criteria: Age between 30 and 40 years Presence of corrected refractive error with asthenopia in the mild to moderate range (myopia up to -6 diopters, hyperopia up to +4 diopters, astigmatism up to 2 diopters), so that the patient needs optical correction, but not complete correction. 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
Exclusion criteria
Exclusion criteria: 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
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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. | — |
Secondary
| Measure | Time frame |
|---|---|
| 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. | — |
