diverging meniscus type of lens
this problem appears because the lens of our eyes are moved farther from the iris.
This results in ,the image is formed just in front of retina and not on it moreever it is also blurred.
This lens helped in decreasing the focal length so that the image is formed on the retina of the eyeball.
