The refraction test is essential for determining the precise prescription needed to correct your vision. At SpecSMART Eye Clinic in Ikeja Lagos, expert optometrists use this test during comprehensive eye exams to help you achieve clear, comfortable sight with glasses or contact lenses.
What Is the Refraction Test?
The refraction test measures how light focuses on your retina to identify refractive errors such as:
-
Nearsightedness (Myopia)
-
Farsightedness (Hyperopia)
-
Astigmatism
-
Presbyopia
It helps optometrists prescribe the correct lens power for clear vision.

Use of the Phoropter: You look through lenses while the optometrist adjusts them, asking which is clearer.

Eye Chart Readings: Confirm clarity at various distances to refine your prescription.

Final Prescription: Customized for each eye and any specific conditions like astigmatism or presbyopia.
