Sunglasses are a vital accessory for summer. Not only do they protect your eyes from UV rays, they can be an important part of your look, so it is important to choose sunglasses that are best suited to your face shape, features, and personal style. The following tips will help you choose the best sunglasses for you:

1. Determine your face shape.
The first step is to decide if your face is round, oval, square, or heart-shaped. Take a photo of yourself directly facing the camera and use a piece of tracing paper to outline the edge of your face. What is the shape of the outline? This can sometimes be difficult to determine, but choose the shape that seems to be the most dominant.

2. Decide which styles work best with your face shape.
Round Faces If you have a round face shape, avoid sunglasses with round frames. Look for angular shapes that can help slim a round face.
Oval Faces Those with oval faces have the most options when choosing sunglasses. Almost any style will be flattering, but slightly square frames often look best.
Square Faces If your face is square, look for styles that can help soften and angular face. Sunglasses with an oval or round shape are often the most flattering option.
Heart-Shaped The key to choosing sunglasses for a heart-shaped face is to balance out a wide forehead and narrow chin. Try tortoiseshell or other colorful frames to help draw attention to your eyes.
3. Check the label for UV protection.
Before you decide on a pair of sunglasses, it is absolutely vital to ensure that your chosen shades have good UV protection. Many eye care professionals believe that exposure to sunlight can contribute to cataracts and other eye disorders, so be sure to check the labels on your sunglasses. If you are unsure of the UV rating, ask your eye doctor to recommend brands with good UV protection.

Check for sunglasses with a sticker that reads "Z80.3." This label indicates that they meet the standards for UV protection established by the American National Standards Institute (ANSI). These sunglasses screen anywhere from 60% to 98% of harmful radiation. The American Optometry Association (AOA) also issues a label, which indicates that 99% of all UVA and UVB rays are blocked.

4. Try something new.
It's all too easy to fall into a fashion rut, so try mixing up your style by choosing a pair of fun sunglasses. Some of the latest popular trends include ultra-sized shades and aviator glasses. Stick with a classic style if you're wary of looking too trendy, but try out a style in a bold or unique color. Don't be afraid to experiment with different styles, colors, and trends when shopping for sunglasses.
