When selecting sunglasses, you may wonder how to pick out the best frames. How do face shapes for sunglasses impact the frames you should get? First, determine your face shape. There are seven basic shapes: round, oval, oblong, triangle, inverted triangle, diamond, and square. Once you determine your face shape, pick a frame that contrasts with the shape. For example, rounded frames are great with a square face; rectangular frames are great with a heart shaped face, and square frames are great with a round face. Make sure they look and feel good on your face. You don ' t want sunglasses that are too small / big, heavy, or just look good and don ' t feel good. The frame size of the sunglasses you select should also be in scale to your face. If you have petite features, don ' t select over - sized frames – they will dwarf your face. Make sure they fit well or they will fall off your face. Be aware of your surroundings if you are playing sports, they might fly off accidentally. Always put your sunglasses in a hardcover case to protect them when traveling out and about; otherwise you might sit on them and mangle them. Some examples of good frames for different face shapes are:
  • Diamond - shaped faces: rimless frames, frames with distinctive brow - lines, or oval frames
  • Square faces: softer edged frames; round, oval, even cat - eyed, also thinner frames
  • Triangle shaped face: colorful frames or cat eye sunglasses, also frames with straight top lines
  • Inverted triangle shaped face: rimless frames, light colors and materials
  • Oblong face: frames that are as wide or wider than the broadest part of the face
  • Round faces: rectangular or squarish frames, thicker frames
  • Oval faces: most frames will look good, but especially square and wrap - around
Effect of Skin Tone and Hair Color on Sunglasses Frame SelectionWhen picking sunglasses, make sure you take into consideration which frames would look best on you. Pay attention to your face shape as well as your coloring to determine what color frames will suit your face. The color of the frames should complement your color tone, which consists of your skin and hair color. Most people have either a cool or a warm skin tone. Cool skin tones have pink or blue undertones, while warm skin tones have a yellow cast. Blond, blue - black, white, and light brown are considered cool hair tones, while warm tones are golden blond, flat black, brown - gold, red, and gray are cool. Warm colored people look best in frames that come in camel, khaki, gold, copper, peach, off - white, or bright red. Cool tones look best in black, rosy brown, plum, magenta, blue, and darker tortoise shade frames. No matter what color frame you end up choosing, remember one criterion that should never be compromised: comfort. Make sure the frames you choose are comfortable and appropriate for what you will need them for.Warnings Wearing ''cosmetic'' sunglasses actually promotes eye damage. Dark lenses reduce available light to the eye, which results in dilation of the eye's pupil. Since the sunglasses do not block harmful UVA or UVB rays, these rays are easily passed into the eye by the dilated pupil. Never wear dark lenses unless they block UVA and UVB rays. Photochromic lenses (the ones that change depending on light conditions) don't work as well in warm conditions (i.e., they become darker in colder weather than in warmer weather). They also don't work at all in a car, as they darken when exposed to UV rays and car windshields inherently block those rays. Polarized lenses reduce glare, but they may also react with the tints in windshields, creating blindspots and diminishing the visibility of LCD readouts.
