Focus on the size of the recipient's face and head to determine a general lens size. Oversized lenses will drown out a small face, while dainty frames and lenses tend to appear beady on a larger face.

Choose between wrap and shield-style glasses, depending on their most likely use. Is the gift beneficiary a sports enthusiast? Wrap glasses may be the way to go. Are the glasses intended as a fashion accessory? If so, focus on typical shield-style glasses instead.

Ask the salesperson if the glasses block 100 percent of UVA and UVB rays and 75 to 90 percent of all visible light rays. Anything less in the way of UV protection is unacceptable.

Try the glasses on for weight and balance. Good-quality glasses will feel sturdy, yet lightweight, and will sit evenly upon the nose and ears.

Wrap the glasses in a stylish sunglass case, which should be included in the price of the purchase. Ask for a solid metal case, as opposed to the softer cloth bags.

Place the glasses in the case, wrap in colorful paper, and tie a sunglass strap around the outside as a bow.
