How to Choose Chrome Hearts Sunglasses

Hot summer comes, it's wise to wear Chrome Hearts sunglasses to protect our eyes. How to choose high quality sunglasses? And how to choose the best shaped sunglasses for your face? Let me figure out these items in the following article.

Of course, sunglasses protect your eyes from harmful ultraviolet (UV) rays, reduce eye strain in bright conditions and protect you from flying debris and other hazards.

How to choose high quality sunglasses?

Understanding UV and VLT

Ultraviolet (UV) rays from the sun can damage your eyes by contributing to cataracts, macular degeneration and growths on the eye, including cancer. All of the sunglasses offered at REI block 100% of UV light.

• UVA rays are the primary ones absorbed by your eyes. While they pose far less concern than UVB, doctors still recommend that they be avoided.
• UVB rays are the main concern for eyes. Long-term exposure to ultraviolet (UV) radiation in sunlight is linked to eye disease. UVB radiation is considered more dangerous to eyes and skin than UVA radiation.
• UVC rays are not a concern, as they are blocked by the atmosphere.

UV protection information should be printed on the hangtag or price sticker of any sunglasses you buy, no matter where you buy them. Also keep in mind that cheap, tinted sunglasses with limited UV protection can actually do more harm than good, as they cause your eye lenses to open up wider, leaving them even more vulnerable to UV rays.

Understanding Lens

Lens Material

The material used in sunglass lenses will affect their clarity, weight, durability and cost.

• Glass—PROS: Superior optical clarity; superior scratch-resistance. CONS: Heavier than others; expensive; glass will "spider" when impacted (but not chip or shatter).
• NXT polyurethane—PROS: Superior impact-resistance; excellent optical clarity; flexible and lightweight. CONS: Expensive.
• Polycarbonate—PROS: Excellent impact-resistance; very good optical clarity; affordable; lightweight and low bulk. CONS: Less scratch-resistance; slightly less optical-clarity than glass or NXT.
• Acrylic—PROS: Inexpensive alternative to polycarbonate, best suited for casual or occasional-use sunglasses. CONS: Less durable and optically clear than polycarbonate or glass; some image distortion.

Lens Color (or Lens Tint)

All sunglass lenses are tinted to cut down on overall brightness and enhance terrain definition. But your choice of tint colors affect your vision by influencing how much visible light reaches your eyes, how well you see other colors, and how well you see contrasts.

• Brown/gray/green—Brown, gray and green lenses are color-neutral, which means they cut down on overall brightness without distorting colors. These darker shades are intended primarily to cut through the glare and reduce eyestrain in moderate-to-bright conditions.

• Yellow/gold/amber—Yellow, gold and amber lenses provide less overall brightness protection, but excel in moderate-to-low level light conditions. They provide excellent depth perception, which makes them perfect for skiing, snowboarding and other snow sports. They also enhance contrasts in tricky, flat-light conditions.

• Rose/vermilion—Rose- and vermilion-colored glasses really do make the world seem brighter. They provide excellent low-light visibility and enhance contrast(perfect for skiing and snowboarding in cloudy conditions). They also enhance the visibility of objects against blue and green backgrounds, which makes them ideal for driving or exploring in forested areas.

• Mirrored or flash coating—This refers to a reflective film applied to the outside surfaces of some sunglass lenses. They reduce glare by reflecting much of the light that hits the lens surface. Mirrored coatings make objects appear darker than they are, so lighter tints are often used to compensate for this.

How to choose the best shaped sunglasses for your face?

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 several 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, if you have a round face, select angular. The picture below is a sample for you to choose sunglasses according to your face shape.

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.

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

For buying qualified sunglasses, suggest you turn to branded sunglasses manufacturer, for example, Chrome Hearts, the Chrome Hearts sunglasses price is reasonable. Hope these information is helpful for you.
