How to choose best sunglasses for you

1)Choose uv400 lens sunglasses that protect your eyes first and foremost.Over-exposure to UV radiation can lead to problems such as cataracts, sunburn and cancer.


If you want to use sunglasses to protect yourself from these risks, you need to find a pair that covers at least 99 percent of UVB and 95 percent of UVB.In addition, also need to know the sunglass shading ability.See how much you can see around the frame. Does the sun shine through the top or side of the sunglasses?

Do you buy sunglasses for exercise or for long periods of time outdoors?Choose a pair of sunglasses that are just the right size. The Arms covers can be made of rubber.If you’re using them for fishing or water sports, you must choose polarized sunglasses, which offer more sunshine protection.



Select the best size for you.Sunglasses come in all shapes and sizes!In general, it is better to contrast the shape of the face with the shape of the frame.For example, if you have a round face, a more angular frame will work best.If you have a square face, a fuller, softer frame will work best.Here are some popular styles:

Mirror – has a reflective coating on the surface.It’s often used by American police.These sunglasses usually come in aviator style or eye mask style.

Pilot – tear-drop shaped lenses and fine metal frames.It is frequently used by US pilots, military personnel and law enforcement personnel.Ideal for any face shape, especially oval.

Traveler — Popular in the 1950s and 1960s.Audrey Hepburn wore these sunglasses in the 1961 film Breakfast at Tiffany’s.

Tawny sunglasses – made popular by John Lennon and Ozzy Osbourne.However, they are not very good at shading light.

Eye mask type – for sports and extreme sports.

Extra Large – sunglasses worn by models and movie stars.Charming and charming.


Choose the shape of your sunglasses based on the shape of your face.Here’s how you can look with a variety of face shapes and sunglasses styles:

Oval face: Often referred to as the “perfect face shape,” an oval face can be worn with any style of glasses.The frame should not be too thick or too thin.Don’t choose frames that are wider than your face.

Square face: Since this face shape has straight lines and a strong jaw and outline, choose round glasses to balance out these features.Make sure the frames are not too thick.Try to choose wider sunglasses rather than square ones with sharp corners.

Round face: Round face features fuller cheeks and chin.Choose polygonal or square sunglasses with angular designs to balance these features.Thicker frames are better.

Long face: Choose larger lenses and polygonal frames to flatter long faces.Consider trendy vintage glasses and sports glasses.

Flat face: Choose darker lenses and frames to accentuate your face.Bright colors can also make your expression more vivid!

5)Colours of lens

Note that lens color affects not only fashion sense, but also the ability to detect contrast and distinguish colors.Some colored lenses can be useful for contrast enhancement, but this often comes at the expense of color discrimination, which can lead to other problems, such as driving when you need to distinguish between the colors of traffic lights.Some sunglasses even come with interchangeable lenses, allowing you to easily change the color of the lenses as you do different things.

Grey lenses can reduce light intensity without compromising contrast or distorting color.

The brown lens enhances contrast by filtering some of the blue light, and is suitable for snow sports, [2] and most hunting when the light is bright and the background is empty.

Amber or yellow lenses can filter out most or all of the blue light and significantly increase contrast, which makes them popular with hunters because contrast is useful for tracking airborne targets.However, these lenses are not suitable for activities that require color recognition, such as driving. They are suitable for snow sports.

Red or orange lenses can be used for snow sports, but only on cloudy days.For hunters, orange lenses are good for spotting earth-yellow targets against an empty background.

Purple lenses are ideal for hunters who need to spot khaki targets against a green background.

Bronze sunglasses can tone down the sky and grass and make golf balls stand out more.

Blue and green sunglasses will enhance the color contrast of yellow tennis balls.

6)Material of lens,PC or AC?

Sunglasses are useless after being scratched.Lenses made of NXT polyurethane have the advantages of impact resistance, flexibility, light weight and high optical clarity, but they are expensive.

Glass is heavier, more expensive and causes “cracks” when it is dropped.

Polycarbonate(PC) has less scratch resistance and optical clarity than NXT polyurethane or glass, but is more affordable.

Polyamide is a less used material that can provide optical clarity similar to glass, but without the risk of breaking.

The scratch resistance of different polycarbonate lenses varies significantly, depending on the hard coated surface used during manufacture.

Acrylic(AC) is cheaper, but has the worst durability and optical clarity.They also have poor heat resistance and often deform.
