Many years ago I was on a beach in Mexico. I was travelling alone. I too wear prescription sunglasses when in the ocean. I wandered into an undertow. I had to fight VERY hard to escape the undertow. I had to decide which to hold onto....my glasses or my bathing suit. My beach towel was too far away.....I kept my siut, escaped the undertow and my glasses $$$ were sacrificed to the ocean gods....

I would like to have lasik. My biggest concern is going three weeks before without my contacts. I really don't know how to wear glasses!
