Cataracts are not the only kind of problems that can be caused by UV rays. You can also start to suffer from macular degeneration. This is when the macula (the part of your retina that allows your vision to be sharp and clear) starts to deteriorate. This can happen if too much UV gets in your eyes. This is why you should wear sunglasses if you go out in the sun alot.
According to www.epa.gov (Environmental Protection Agency, USA), all researches have shown that UV radiations increase the risk of some forms of cataract (a form of damage of the eye that manifests itself by a loss of transparency of crystalline). If it is left untreated, cataract can lead to blindness. Environmental Protection Agency mentions include other ocular lesions caused by the exposure to UV radiation: the growth of tissues that can obstruct the view, skin cancer around the eye, degeneration of retinal part which is responsible for acute visual perception. All this can be avoided with proper eye protection.
