which lens tint color of prescription sunglasses can effect pale blue sea?

[mens glasses]

I like buy sunglasses with big brands, such as, Dior, Rayban, or Police, etc. BUt they are too expensive, i want to know which lens tint color can effect the sea with pale blue color? My girl friend bought a pair of prescription sunglasses from the www.cheapprescriptionglasses.net, she selected the AW1015 in violet color and tinted with the dark rose, so beatiful and fashion of that! The price $19.95 is low and the quality is better!
