Refractometry of the eye is a diagnostic method used to measure the refractive power of the eye. It helps determine how light rays pass through the cornea and lens of the eye, and where they focus on the retina.

The main objectives of refractometry are as follows:

1. Diagnosing refractive errors: refractometry detects refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related farsightedness).
2. Selecting eyeglasses and contact lenses: based on refractometry results, an eye doctor can precisely determine the parameters needed for corrective eyeglasses or contact lenses.
3. Monitoring changes in vision: regular refractometry allows tracking changes in vision, which is especially important for children, older adults, and those already diagnosed with vision problems.
4. Preparing for surgical interventions: refractometry is essential for preparing for various eye surgeries, such as laser vision correction or lens replacement.

The refractometry procedure is conducted using a specialized refractometer device. It is a non-invasive and painless examination that takes only a few minutes
