Human eye: accommodation and near point (Hindi) | Human eye | Physics | Khan Academy

Why do distant things get blurred when we concentrate on things close to us? Why can't we see things which are very close to us? Let's explore how our eyes work and get answers to questions like these by exploiting the power of ray diagrams.

    @khanacademy, the video is very nice but sir i have a doubt so kindly solve it. My doubt is- In the video you said that the glass slab does not have curved surface thus the parallel rays will not suffer any refraction but i think the no refraction case is possible only when the light rays will incident on the glass slab at 90 degree so sir kindly explain that how does the curvature effects the bending of rays by taking some other examples too. thank you!
