We can see distant and near objects clearly because of the property of accommodation of eye. Accommodation is the name given to the ability of the lens of the eye to change its focal length and produce focused images of both distant and near objects on the retina.
Ciliary muscle helps in changing curvature of the lens. They are attached to the lens and contract or release to change the lens shape and curvature.
No image is formed at blind spot because there are no photo receptors, i.e., cones and rods to detect the light and send it to brain.
