You can go to a store and pick a pair of sunglasses easily just by gauging with your own eyes. What you may not be aware of is that there is a specific way the accessory should fit your eyes and the space above the nose. This is not a matter of guessing but a critical thing to understand. Sunglasses should be comfortable on you. What may be fitting to someone else may not be the case for you because people have different face sizes and shapes. Faces can be round, oval, square, long, flat or heart shaped and thus is not just the case of "one size fits all". Here is what you need to know about getting perfectly fitting sunglasses.

Know You Face Type

There are various sunglasses specifically designed for a given face type. People have different face types, which may vary significantly according to ancestral characteristics. For example, Chinese or Asians may have a wider face while western people have narrower face. You may find out that one has an oval face, square, round or long. After knowing the shape of your face, you can then match it to the specific sunglasses.

• The oval face.

This face type seems to have a universal choice. It is perfect for any style of sunglasses and nothing can ever go wrong for you. The only thing you have to put into consideration is the size of the frame; which should neither be too thin nor too thick. They should also not be wider than your face type.

• Square face

This face has pronounced jaw-line and edges. Wearing round and wider sunglasses will make you balance these features. The frames should not be too thick. Never put on rectangular glasses with sharp corners because it will end up exaggerating you facial features.

• Round face

This face features plumper cheeks and chin. Therefore, polygonal or square sunglasses with an angle design is perfect for it. The frames should be thicker.

• Long face

This face has elongated feature from forehead to chin. Sunglasses with larger lenses and polygonal frame will help modify the long face.

• Flat face

Sunglasses with darker lenses and frames will serve to highlight the contours of the face. Bright colors can be helpful in making the expression more vivid.

• Heart-shaped face

This faceis widest at the temples and narrower at the chin.It goes well with sunglasses having rectangular frames. They are best with aviator, rimless, shield or butterfly styled frames.

The Frame Size

Frames are made of either plastic, nylon, metal or at some point, wood such as ebony. They help the glasses grip well on the face of the wearer. Nylon frames are most preferred, as they are lightweight and flexible. Unlike metal frames, they can bend easily and return to their initial state without breaking even when pressure is applied to them.

A fitting pair of sunglasses should have the frame correspond to the overall width of the face. Small or narrower faces blend well with smaller frames while wider faces should have wider  frames. The thickness or thinness of the frames depends on the face shape. For instance, square faces blend may go well with thick frames.

Nose Bridge

The nose bridge provide support between the lens and the face. Different people have different nose sizes; some are big, some are small, others are long while others are flat or narrower. People with large noses need sunglasses with a lower nose bridge. Those with medium sized noses need a low or medium nose bridge while those with small noses require sunglasses  with high nose bridges.

In some cases, some companies produce sunglasses that can be adjusted to fit the nose size. If you can't find any other fitting sunglasses perfect for your nose, then you should go for the adjustable ones. This is especially important to sports people who have to ensure the sunglasses comfortably stay in place throughout the exercises.

Comfort When Worn

The sunglasses should never feel like another extra load you've just carried. Basically, observe  the following;

• They should not pinch around your head when worn.
• The eyebrows should be above the frame. At least it should me half the eyebrow or more.
• The eyeball should be directly at the center of the lens; both from the right or left. The eye should fill the top half of the lenses.
• The weight should be evenly distributed between the ears and the bridge of your nose. There should be no squeezing or pressure on these areas.
• The eyelashes should at no point touch the frame or lenses. This happens when you are blinking or taking off the sunglasses.
• The lens area should not be too small. At least you can always look for a size bigger than you rather than a smaller one.
• The sunglasses should be close-fitting but not too tight. They should fit well lest they fall off or slip when bending down.

Lens type

The color of the lenses identifies your fashion statement and shows how well you can contrast or differentiate colors. There are various shades of colors such as black, brown, purple, orange, red, gray or green. The lens should always complement your coloring; such as skin color, hair and the apparels. You have to make sure that the lens color is deep and dark enough that the eyes are barely visible. For small eyes, consider trying out dark lenses as they can appear to increase the eye size.Short faces will look overpowered by deep aviator styles. For dark skins, sunglasses of a light color with vibrant frames will blend well and stand out.
