    7 Ways To Know The Quality of Your Sunglasses

    Should you do a sunglasses test online? No need, you just have to be a little more attentive. We know how disappointing it can be to want a pair of shades but can't get it because of their quality. High end sunglasses will be around for a long time. So, you might as well just look for the small details that make the big difference. Let's check them out

    1. Look For The UV Protection Label

    Trusted brands will produce the best sunglasses for eye protection. So, they will always indicate the type of UV protection on their labels. You can come across them in two ways: you either see the 100% UV protection or the UV filter category UV 400.

    Sunglasses with a UV 400 lens block all light rays with wavelengths of up to 400 nanometers, which covers all UVA and UVB rays. The number one advice would be to always look out for either of these labels when you're shopping for wraparound sunglasses to make sure they provide the best UV protection for your eyes from sun exposure.

    2. Test Your Sunglasses With a UV Flashlight

    How can you tell if sunglasses are polarized? This is a question that is often asked. There is a simple test at home. It may seem ridiculous but it actually works! If you have a UV flashlight at home, you can use it to test your sunglasses' quality. Shine the light against any paper money. When the watermark from the bill lights up, put your prescription sunglasses in front of it. If it disappears, it has UV protection. It's as simple as it gets!

    Apart from releasing UV light, which your eyes can not see, the flashlight will also release visible light. Some of the bright light will make it through your glass lenses and illuminate the paper. Just make sure to distinguish the differences between the straight UV light compared to when it passes through the lens, and the visible light hits the test subject.

    Remember that if the visible light cannot penetrate your lens, then that would be abnormal, and in this case, you wouldn't be able to see anything through your sunglasses at all!

    3. Check The Expiration Date

    Well, this is odd. Did you know sunglasses have an expiration date? They do! The normal expiration of a pair of sunglasses is when it reaches two to three years and above. But, why do sunglasses expire? When they’re exposed to UV rays over time, the UV protection and special lens coatings of the lens gets damaged. As a result, it no longer becomes effective.

    4. Watch Out For Dark Sunglasses

    It is a common misconception to think that the darker your sunglasses are, the better they can protect your eyes from the sun. The reality is, the darkness of the lens doesn’t necessarily mean it can block UV rays more effectively. If the sunglasses are dark but not equipped with 100% UV protection lenses, then they are not protecting your eyes efficiently.

    Dark high-quality sunglasses are mainly great to filter out ambient light and glare. However, there is a problem with dark sunglasses: they make your pupils open which lets more light actually enter your eyes. When the sunglasses aren't UV protected, the extra exposure to UV rays increases your chances of getting cataracts and macular degeneration. If you're opting for dark sunglasses, make sure to check that they are equipped with 100 percent maximum uv protection lenses.

    5. Know What Polarization Is

    Polarized sunglasses are becoming more and more popular to own. For a good reason, of course! Polarized glasses re equipped with a filter that only lets vertically-oriented light pass through and blocks horizontally-oriented light. Three things happen in this case:

    • Polarized lenses reduce glare.
    • They enhance contrast.
    • They improve visual clarity and comfort.

    Although polarized lenses are not essential for blocking the sun’s UV rays, however, they are an added protection for your eyes. As a result, they allow clearer vision in the sun, which can be useful specifically when driving or play sports.

    Polarized sunglasses are strongly recommended if you're looking to buy a pair of good quality sunglasses. But, keep in mind that there are a few circumstances where polarized lenses may be less appropriate such as

    • Night Driving
    • LCD Screens
    • Auto Dashboards
    • Clocks
    • Instrument Displays

    Educate yourself on the difference of polarized sunglasses Vs non-polarized, it might come in handy when you're choosing high quality and durable frames.

    6. Check with an Optometrist

    If you want to be make sure that your good quality sunglasses are suitable for eye protection, you can have them tested by simply taking them to the nearest optical shop. Opticians and Optometrists have the right tools to test your sunglasses and find out what type of sunglasses lenses they are made of.

    As per Dr. Andrea Thau, a New York-based optometrist and past president of the American Optometric Association, there is a way you can determine whether your sunglasses are safe or not by bringing them to your optometrist during your yearly comprehensive eye examination. She states: "We have methods of testing their UV protection, and unluckily, you cannot tell if they have UV protection from just looking at them."

    7. Check The Lens Quality

    The most crucial factor to check the quality of your sunglasses photochromic lenses would be for your optician to have a look. As per Muse Amawi, general manager of SEE Eyewear and New York optician, "The quality of the lens and mirror coating is what's important." Amawi also added, "Cheaper frames can be effective as long as you are getting them from an optical brand and not a fashion brand."
