Not everyone can be lucky enough to be able to have lasiks surgery either due to the expense or due to medical reasons. Not everyones eyes can qualify for Lasiks. I happen to be one of those who’s eyes will not qualify for the surgery. So the options boil down to have a mask with corrective lens built in to it, wearing contacts, which I do use, and a third option is a Mask made by HydroOptix. This Mask incorporates some of the latest technology from NASA. I also use this mask as well. It does an incredible job of providing me with excellent vision too. Hope this helps.
