Eye refraction refers to the bending of light as it enters your eye. To achieve clear vision, light must be precisely focused onto the retina, the light-sensitive tissue at the back of your eye.

Ordinary eye tests are imperative for observing your eye wellbeing and recognizing vision issues. An eye refraction exam is specifically designed to identify and measure refractive errors.

By surveying your eye’s capacity to shine light, your eye care proficient can decide the most fitting remedial focal points to improve your vision.

Preliminary Tests: Before the refraction process begins, your eye care professional will conduct preliminary tests to evaluate your overall eye health. The evaluation of eye muscle function, visual acuity, and any symptoms of eye diseases are all possible outcomes of these tests.

Auto-Refraction: One of the initial steps in the eye refraction exam involves using an autorefractor. This robotized instrument checks your eye’s refractive mistake and gives a surmised solution, which fills in as a beginning stage for additional refinement.

During this process, you will be asked to look through a phoropter, a device containing various lenses. The optometrist or ophthalmologist will be able to choose the lenses that will provide you with clear vision with your feedback.

Near Vision Assessment: Depending on your needs and age, your eye care provider may also assess your near vision. This is important if you require correction for activities such as reading or using digital devices.

Eye Health Examination: Following the refraction tests, your eye care professional will conduct a thorough examination of your eye’s health. This step is crucial for identifying any underlying eye conditions or diseases that may require further attention.
