Unless I'm missing something here, I thought contraction of a muscle shortened it. Therefore, you would expect a contraction of the ciliary eye muscle to shorten the distance to the lens, thus tautening the suspensory ligaments and flattening the lens (for distance vision). My book tells it the other way round: ciliary muscle contracts, suspensory ligaments slacken, lens thickens. Please help my confusion !
Re: Why does the CONTRACTION of ciliary muscles cause the eye lens to thicken ?
