Brief summary: According to the World Health Organization's statement published in 2014, 43% of visual impairment is overhauled by uncorrected refractive errors. The change of body and angle of light waves while undergoing changes in the environment due to the temperature difference between the environments is called refraction. The refractive errors found in the eye can be discovered as myopia, astigmatism, hyperopia, and presbyopia. As there are different prevalence methods in eye refractive errors in various publications. According to many studies in the literature, eye exercises in many conditions such as convergence collapse, accommodation dysfunction, movement center of the eye, digital eye strain and dry eye are curative and therapeutic without any control. With eye exercises, blood is applied to the ocular region, the humor is stimulated, the tension of the extraocular muscles is reduced, the coordination between the eye muscles is increased, the eye fatigue and stress are reduced. Depending on the effects of these effects, positive changes are seen on vision tests. Although there is a different view in the literature that includes these eye exercises and their benefits, it has been found to be insufficient in current studies. More work needs to be done in this area so that these results can be stated better and more clearly. With this study, investigators aim to shed light on what can be done in this field by filling these residents in the literature and to examine the visual function and quality of life of eye exercises.


Eligibility criteria: Inclusion Criteria:

be between the ages of 18-65, Having any refractive or visual impairment (myopia, hyperopia, astigmatism) by an ophthalmologist, not have other eye problems in addition to these vision defects, to score at least 24 on the Standardized Mini Mental Test.

Exclusion Criteria:

having undergone any eye surgery (including laser operations), have a prosthetic eye have congenital vision loss, have any disease that will affect the eyesight. Individuals meeting these criteria will not be included in the study.
