On the contrary to rumours about sharks,pirates,storms, and
cyclones,UV-light is a real threat to cruisers.Not only is the incidence
of skincancer significantly increased among people being at sea in the
tropics but also eyeproblems and then especially an increased risk of
cataract((lensinjury).Not being aware of this,and thinking that sunglasses
is impractical,I didn´t use sunglasses in the beginning.Nowadays I
consider it being an important part of sunprotection.
