1 put on a mask that keeps air in front of cornea
2 rely on a STRONG lens that can change from air-living to water living eg: otter
3 Have a FLAT cornea (to remove its influence) and then use a WATER-LIVING style lens eg. Penguin, flying fish
4 Have two pairs of eyes - one for each environment eg. Four-eyed fish
5 Use a WATER-LIVING style lens in the water and bi-pass the cornea by using a PIN HOLE pupil on land eg. seal
