There are various treatment methods for vision defects that can negatively affect your daily life. The most common and most commonly known visual defects are refractive problems such as myopia, hypermetropia, 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 subheadings.

Myopia

Myopia appears to be one of the important reasons that may cause vision loss to the patient. A person with myopic vision defects can clearly see close distances while having difficulty in seeing long distances. 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 defect, is classified as Axial and Refractive Myopia. While axial myopia is caused by the long structure of the eyeball, refractive myopiais associated with the positioning of the cornea or lens. Depending on the refractive power, it is classified as Myopia, High Myopia, and Low Myopia.

Hyperopia

Hyperopia is one of the other important causes that may cause vision loss to the patient. The patient with hyperopia vision defect has difficulty in seeing close distances. The anterior posterior length of the eye is a refractive defect in which the incoming rays are focused behind the retina, not above it, when the cornea or lens is less refractive. In the treatment of hyperopia, glasses, contact lenses and refractive surgery methods are used.

Astigmatism

Astigmatism is one of the important refractive errors. There are disturbances in the interpretation of the object by the brain by preventing the incoming rays from focusing in the retina. A patient with astigmatism has blurred vision regardless of distance. Myopic astigmatism differs as hypermetropic 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 disorder that can be determined during a general eye examination. Age-related vision problems are mostly noticed by presbyopia, when the patient does not read articles that are more than 50 cm away when reading something, and blurring of the image. The patient usually needs brighter light when reading more closely than before. In this way, impaired vision is noticed by the patient.
