Will an image be formed on the retina when the object is at a far distance? Will a clear image be formed ?

Answer

To get a clear vision, the image of objects from far point upto the near point must be obtained òn the retina itself. When we look at nearer objects, the ciliary muscles related to convex lenses in our eyes are contracted and the curvature of the Iens increases. The focal length decreases. While looking at far objects the ciliary muscles are relaxed and the curvature of the lens decreases. The focal length of the.fens increases.
