Very few eye injuries occur while playing golf. Those that do are a result of a stray ball, or standing too close to someone while they are swinging. However, golf glasses are an accessory that can help improve your game. Most golfers have a pair of golf shoes, but few have a pair of glasses specifically for golf. Most just wear their regular sunglasses. However, glasses made specifically for golf can help you better distinguish fairways and greens, help you follow your ball in flight, and most importantly, not interfere with you swing. At the same time, they will protect your eyes from ultraviolet light, and from the rare instance of injury. Here is what to look for:
Ultraviolet Protection: Since golf takes place outdoors, you glasses should protect you from 100% of ultraviolet radiation. (See UV and its Effects on the Eyes for more information on UV).
Lens Color: A lens that absorbs blue light will help you read greens better and follow your ball in flight. The greens and white ball will be enhanced, while the blue of the sky will be muted. Look for brown or amber lenses to increase contrast. Or, some people prefer more natural vision and lenses that do not distort. For those, choose a neutral gray or G-15 green gray lens for true color perception. Some golfers also like polarized lenses to reduce additional glare especially off water hazards. However, polarized lenses can make it harder to read the greens and they will tend to make surfaces look flatter.
Frame Styles: Most golfers have found that their regular pair of sunglasses interferes with their swing. As they go to swing, their head turns slightly, and the bottom edge of the frame interferes with the direct gaze of the ball. Look for frames that do not have a frame on the bottom to interfere with your line of sight, or oversized frames so your gaze does not cross the frame border.
Frame Fit: Since you start your golf swing looking down, improperly fit glasses can slide off the nose and distract you. Make sure you choose frames that have temples that can be adjusted to fit so that they do not slide down the nose.
Prescription Lenses: Most golf glasses can be fit with prescription lens. However, those who wear a bifocals or progressives probably have noticed that they must put their head down a little more to properly see the ball. This is because the bifocal often interferes with the field of view, since the ball on a tee falls into your intermediate or distance vision, not your near that a bifocal is designed for. This creates an uncomfortable head position. A golfer that needs both distance and near corrections should consider special golf lenses. This would be a bifocal fit very low and temporally so that you can easily see the ball in the distance range without creating an uncomfortable head position, while at the same time, have the bifocal there to read and record on a score card. Stick-on bifocals are also a popular option as they can be removed when not needed.
