Visions | Refractive Errors

Presentation by ophthalmologist João Pedro Cardoso, Optiangra
This presentation explains the origin and distinctive characteristics of refractive errors that affect the way light passes through the different structures inside the eye, interfering with the sharpness of the image formed on the retina and configuring cases of myopia, hyperopia, astigmatism and presbyopia. At the same time, a free eye screening will be organised.
