Vision in Focus (Visão em Foco)

An educational mission about human vision. Explore six eye parts in an interactive atlas, watch the pupil respond to light and solve 12 challenges about light capture, interpretation and corrective lenses.

Choose lenses for myopia, hyperopia, astigmatism and presbyopia with feedback and simplified focus models. Play without a timer and try again whenever needed.

Click or tap answers. On desktop, you can also use keys 1–6 and Enter to continue. Portuguese and English are available in the game. Simplified educational diagrams; not a substitute for an eye-care examination.
