Refraction of the Eye Clinical

Refraction of the eye is the process of refraction of light in the eye, which occurs due to its curvature. Normally, the eye is spherical in shape, which allows light to focus correctly on the retina. However, with some diseases or visual impairments, refraction can be impaired, leading to various vision problems.

Clinical refraction of the eye is one of the important methods for diagnosing vision. It is carried out using special devices - refractometers, which allow you to measure the curvature of the cornea and lens of the eye. The results of this study allow us to determine the degree of refractive error and prescribe appropriate treatment.

The refraction of the eye can be normal, hypermetropic, astigmatic or myopic. With normal refraction, light is refracted correctly in the eye, and the image is formed on the retina without distortion. Hypermetropia is a condition where the eye has too much curvature, causing light to be unable to focus correctly. Astigmatism is a disorder that occurs when the cornea or lens of the eye has different curvatures in different directions. Myopia is a condition in which the eye has too little curvature and cannot refract light correctly.

Diagnosis and treatment of eye refraction are important aspects of ophthalmology. They help determine the cause of vision problems and prescribe the correct treatment, which may include lens correction or surgery. It is important to understand that eye refraction is not a permanent condition and can change with age, so regular eye exams are essential to maintaining good vision throughout your life.



Refraction of the eye is the process of refraction of light in the eye, which allows us to see the world around us. Normally, the eye has the correct shape and optical properties, which allows it to focus images on the retina. However, in some cases, refraction can be impaired, leading to various eye diseases such as nearsightedness, farsightedness and astigmatism.

Clinical refraction is an eye examination method that is used to determine the shape and optical properties of the eye. It is carried out using special equipment such as refractometers and keratometers. During the examination, the doctor measures the refractive power of the eye and determines its optical power.

Myopia is a condition in which the eye has too little refractive power. This causes the image to focus in front of the retina rather than on it. Myopia can be caused by various factors such as genetic predisposition, poor diet, lack of sleep, etc.

Farsightedness is a condition in which the eye has too much refractive power. This also causes the image to focus in front of the retina. Farsightedness can be caused by age, poor diet, lack of sleep and other factors.

Astigmatism is a condition in which the shape of the eye is not correct. Astigmatism can be caused by various reasons, such as injury, infection, or birth defects. With astigmatism, the image cannot be focused on the retina, resulting in blurred and distorted images.

Various methods such as glasses, contact lenses and surgery are used to treat nearsightedness, farsightedness and astigmatism. The choice of treatment method depends on the degree of refractive error and the individual characteristics of the patient.

In conclusion, clinical refraction is an important tool for the diagnosis and treatment of various eye diseases.
