Free vision test by appointment with an optometrist
How to check your eyesight for free and what is included in the test?
Vision test - is a process during which an optometrist determines the presence of vision problems and selects the best glasses to correct them.
Checking your vision with an autorefractometer
is an important component of the eyeglass lens fitting process.
Autorefractometer - is a device that allows you to measure the optical power of the eye, that is, the light reflection of the internal structures of the eye, such as cornea and vitreous body.
During the procedure autorefractometryThe optometrist performs several tests to assess visual acuity. The main tests performed with an autorefractometer are as follows:
-
-
Measurement of eye refraction.
During this procedure, the optometrist measures the eye's refraction, which is the eye's ability to focus light. He or she uses an autorefractometer to measure the optical power of the eye and uses this data to determine the optimal lens power for vision correction.
-
Measurement of astigmatism.
Autorefractometry allows the optometrist to determine the presence of astigmatism when the eye cannot see both horizontal and vertical lines clearly at the same time. The autorefractometer allows you to accurately measure the difference between the horizontal and vertical meridians of the eye, which helps determine the degree of astigmatism and optimal correction.
-
Corneal diameter measurement.
Autorefractometry allows the optometrist to measure the diameter of the cornea and provides information on the exact size for the correct selection of contact lenses.
-
Determination of the refractive index.
During this test, the device allows the optometrist to determine which parts of the eye are responsible for light refraction, namely the cornea, vitreous and retina. This allows for a more accurate determination of vision correction and selection of optical and contact lenses. All these tests on the autorefractometer allow the optometrist to obtain detailed information about eye health and optimal vision correction for the patient. The autorefractometry procedure is comfortable, painless and does not require patient preparation, and the measurement process itself does not take long.
-
Depending on the result of the autorefractometer vision test, the optometrist performs additional tests, such as
-
Determination of the dominant eye.
-
A one-sided cover test.
-
An alternative cover test.
-
The nature of vision.
-
Checking the center distance.
-
Correction selection.
-
Selection of medical centers.
-
Setting binocular balance.
-
Checking the previous correction.
-
Convergence check.
-
Checking visual acuity without correction.
-
Close-up depth of focus for vision correction.
Pass all visual tests,
You can get your eyesight checked for free at your ABM Optics in your city, only by appointment.
Optometrist's vocabulary
Autorefractometer - is a device used in optometry to objectively assess the refraction (light refraction) of the eye. It automatically measures the refraction of the eye and is able to quickly and accurately determine the minimum required corrective lens gradient that a patient needs to achieve optimal vision. The autorefractometer helps ophthalmologists and optometrists to select the best glasses or contact lenses for each patient, helping to achieve better vision and reduce the possibility of eye diseases.
Autorefractometry - is a vision examination method that uses an autorefractometer to objectively assess the refraction (light refraction) of the eye. The autorefractometry procedure allows you to measure the refraction of the eye without the patient's participation in determining the optimal lens for vision correction. During the procedure, the patient looks at a luminous object through a special device that reflects light back to the retina and measures the refraction of this light. The autorefractometer then automatically analyzes these measurements and displays the refraction of the eye in diopters. This method of examination is fast and convenient, and the results of autorefractometry measurements help ophthalmologists and optometrists to choose the right lenses or glasses for your vision correction.
Cornea of the eye - is a transparent, dome-shaped structure that covers the front of the eyes of humans and animals. It is the first lens through which light passes, which is then refracted by the lens of the eye and focused on the retina to form an image. The cornea has a very high transparency and a smooth surface, which allows it to provide high-quality light transmission to the eye lens.
The diameter of the cornea can be measured with an autorefractometer. Using algorithms built into the device, the autorefractometer determines the thickness of the cornea and the diameter of the central zone.
Corneal diameter measurement is important for optometric examinations and procedures such as contact vision correction. For example, corneal diameter is an important parameter when choosing the optimal contact lens size.
