There are various treatment methods for visual defects that can negatively affect your daily life. The most common and most well-known visual defects among the public are refractive problems such as myopia, hyperopia, astigmatism, and presbyopia. Glasses, lenses and surgical methods are determined by experts according to the strength of the refractive error. The most common visual defects are detailed in the following sub-headings.
Myopia Myopia is one of the important causes that may cause vision loss to the patient. While a person with myopia has difficulty seeing far distances, they can see close distances clearly. Myopia is experienced when the eye structure is long or when there is a curved structure in the cornea. Myopia, which is considered a refractive error, is classified as Axial and Refractive Myopia. Axial Myopia is due to the elongation of the eyeball structure, while Refractive Myopia is associated with the positioning of the cornea or lens. Depending on the refractive power, it is classified as Myopia, High Myopia, and Low Myopia. Hypermetropia Hypermetropia is one of the other important causes that may cause vision loss to the patient. The patient with hyperopia vision defect has difficulty seeing close distances. It is a refractive error in which the incoming rays are focused behind the retina, not on the retina, when the anterior-posterior length of the eye, cornea, or lens are low refractive. In the treatment of hyperopia, glasses, contact lenses and refractive surgery methods are used. Astigmatism Astigmatism is one of the important refractive errors. By preventing the incoming rays from focusing on the retina, there is deterioration in the interpretation of the object by the brain. A patient with astigmatism has blurred vision, regardless of distance.
It is differentiated as myopic astigmatism, hyperopia astigmatism and mixed astigmatism. Appropriate treatment methods for astigmatism are determined by specialist physicians. Presbyopia The mechanism in the human eye weakens towards the end of the 40s. This causes a gradual deterioration in near vision. Presbyopia is a condition that can be detected during general eye examination.
Presbyopia, a vision problem caused by age, is mostly noticed when the patient does not read anything further than 50 cm, and the image becomes blurred. The patient usually needs brighter light when reading more closely than before. In this way, the weakening of vision is noticed by the patient.
