I have been using prevencia for 4 months. It has lot of disadvantages, hence never thought of buying it.
Being special coated lens, it is dangerously getting scratched easily
Easily getting smugdes.
Sticks to the dust oil quickly
Cleaning is very tough and need to too much of care for mainitaining.
Just avoid this and go ahead for non coated lenses. Our Eyes can do magics of accomdating any lights, just dont think about these Blue rays etc. All you need to do is to keep good ergonomics on Eyes while work and dip your eyes in cup of water daily etc
