The best golf sunglasses are multi-functional. They not only keep you looking cool on the links so you can impress the drink cart girls with your sense of style, but the glasses also keep the sun's glare out of your eyes and protect you from the harmful rays.

The top brands in the market include Bolle, Oakley, and NYX, and as top brands tend to do, these sunglass manufacturers attach a pretty big price tag to their merchandise. However, if you just have to have them you may not mind shelling out the cash. But if you've just dropped a few thousand on clubs, collared shirts, and a country club membership, you may want to cut corners with your sunglasses.

When you're trying to save some money, some of the best golf sunglasses are the cheapest golf sunglasses. In this case, cheap does not necessarily mean poorly made. We don't mean the $5 pairs you can buy at your local convenience store.

Inexpensive glasses can be just as technologically advanced, comfortable, and good looking as the brands with price tags in the hundreds. They can be made with lightweight polycarbonate materials so they are barely noticeable once they're on your face. They can also come with special attachments to loop the glasses around your ears, so no matter how roughly you hack at the ball, those glasses won't slip off!

Most importantly for your eyes' health, the best golf sunglasses come with lenses that block 100 percent of the harmful ultraviolet rays from the sun. Shop for glasses that block both UVA and UVB. The higher the nanometer rating, the safer the lenses are for your eyes.

With inexpensive UV-blocking sunglasses, you'll have slightly less reason to worry about cataracts or other eye conditions later in life. You'll have more cash in your pocket to purchase equipment, balls, green fees, and, most importantly, frosty beverages from the drink carts. And you'll look pretty cool doing it, too.
