Sunglasses offer protection from the sun's damaging ultraviolet rays and that's one offer you definitely want to accept. The eyes are the windows to the world, and these complex yet delicate body parts need all the protection they can get. You can't see them, but damaging ultraviolet rays are always present, even when the sun isn't shining. Sunglasses that block these rays can help keep the eyes healthy.

Who should wear sunglasses? Anyone who wants to limit the eye's exposure to this type of damage. It's true that clouds block most ultraviolet rays from reaching the ground, so it's not as important to wear eye protection when the sun's not shining. But when it is, better get into the habit.

Age shouldn't be a factor either, meaning that children's eyes are just as susceptible to these hidden dangers. And when you consider that they generally spend more of their time outdoors, eye protection for children is an absolute must.

How much is enough? The sunglasses you choose should have lenses that block at least 99% of the ultraviolet light. There'll be a sticker on the lens or a tag attached to the frame that advises how much UV protection each pair provide so be sure to read it. If you'd don't see a sticker or tag, select another pair.

And if you're worried about being fashionable, find something else to worry about. With literally thousands of styles of sunglasses to choose from, you're sure to be something suitable for everyone in the family. Wire frames or plastic, rectangular-shaped lenses or heart-shaped, with or without monograms, rhinestones, or other notable logo, the choices are endless.

And because it's so important to keep ultraviolet rays away from eyes, even those who wear eyeglasses have options. Prescription sunglasses are available through an optician in a wide range of prices and styles.

Next time you think it's no big deal, remember that over time, excessive exposure to UV rays can lead to the onset of eye conditions including retina damage and even cataracts. So do your eyes a favor - eat your carrots and be sure to carry your sunglasses with you at all times!
