Blue Light Blocking Glasses - Frequently Asked Questions
Blue light-blocking glasses are specially designed to filter out the blue light emitted by electronic devices to protect your eyes from its harmful effects. With use of special technology, these lenses decrease the transmission of ultraviolet light between the wavelengths 440 and 500 nanometers. The light-filtering effect of the lenses reduces eye fatigue, which helps those who have to use digital devices all day long.
At SmartBuyGlasses online, we have blue-light-blocking eyeglasses and the zFORT add-on available for prescription lenses. zFORT® is blue-light blocking technology that helps to block a portion of blue light wavelengths between 380 and 500 nm from reaching your eye. The blocker scatters the wavelengths away from the eyes, acting like a shield of protection from light that can potentially cause detrimental damage.
People who have sensitivity from blue light, experience fatigue and dryness in the eyes when working on digital devices, and those who cannot sleep because of their screen usage should consider wearing blue light glasses.
Those who have to stare at the screen at work or just before they sleep could also benefit from these blue light-blocking lenses. When these lenses filter out the blue light, their eyes are protected and do not dry out because of the constant staring. Many people who have to stay on their phones just before bedtime or have prolonged screen use also benefit from blue-light-blocking lenses since the lenses allow them to maintain their sleep patterns, even with continued digital exposure.
Except for Polaroid blue-light-blocking glasses, all other brands in the collection at SmartBuyGlasses online are suitable for prescription lenses and specialised coatings. To add your prescription number, first click the ‘Buy with Prescription’ or the ‘Buy Frame and Lens Deal’ button on the product page to enter your prescription number manually, or upload an image of your prescription. You can also add an astigmatism number at this point.
In the next step, you can select the lens index and coatings for your chosen frame. The lens index determines the thickness of your lenses and the coatings allow better protection. Choose the package that fits your budget and requirements. In the add-ons options, you can choose zFORT blue-light blocking lenses which allows you to get blue-light-blocking lenses with your prescription number and chosen coatings.
There are a number of options available for blue light glasses in the collection. This includes rectangular frames, oval frames, and even the stylish, aviator style. You can also pick geometric frames from any brand you like or the SmartBuy Collection and get them fitted with zFORT blue-light blocking lenses to get your pair of customised lenses.
So, even though you’re picking blue-light lenses for their functionality doesn’t mean you should cut back on style and fashion. Here at SmartBuyGlasses online, you can browse through a huge range of brands online. You can go for luxury brands like Miu Miu, Gucci, Burberry, Prada, Ray-Ban, Dita, and Oakley to get a pair of frames that complement your face, bringing out your best features. Then, use the SmartBuyGlasses ‘Buy with Prescription’ option to customise your glasses with blue light-blocking lenses.
The care instructions for blue-light glasses are not any different from those for regular eyeglasses. You should keep these eyeglasses safe from impact and scratches by keeping them in a safe place when not in use and always using microfiber cloth for cleaning your lenses.
You should also keep your glasses clean and free from oil and grease. To do this, wash your glasses with water. Take a drop of dishwashing solution on your fingertips and rub it onto the lenses. Then, rinse away the soap with water again. Dry the lenses with microfiber cloth before wearing your frames.
