What Kind of Lens Coatings Do Our Glasses Have?
Lens coatings are significant because they play a vital role in providing durable and long-lasting lenses for your eyeglasses. Unfortunately, not everyone knows the different types of lens coatings you can choose from; or worse, some didn’t even know such protective layers exist.
If you need a new pair of eyeglasses, here is a guide on lens coatings for glasses and what they are useful for:
Anti-reflective or AR coating is a microscopic multilayered coating that eliminates reflections from the back and front of your eyeglass lenses. Thus, it prevents distractions caused by the reflections.
Such lens coating can also eliminate glare, that’s why it can also be called as anti-glare coating. This is the best option for people who are always behind the wheels because it can surely avoid sudden blindness caused by heavy road lights, car blinkers, and heavy headlights.
This lens coating should be present on all eyeglass lenses, particularly to polycarbonate and high-index lenses because they reflect more light than their plastic and glass counterparts.
Plastic lenses are convenient to wear because they are light but strong. However, they are prone to scratches and tear.
Anti-scratch coating is a special substance with hard lacquer. It is applied not just to make the lenses scratch resistant but also to assure consistent visual quality and durability. It is your glasses’ first line of defense.
This lens coating is best for children and people with an active lifestyle.
Keep in mind that such lens coating can’t completely protect your lenses from wear and tear. Extra precautions, proper handling, and storage are still highly recommended.
Lenses like polycarbonate and high-index are already equipped with anti-scratch coating properties.
After we got out of the car or an air-conditioned public transport, there are moments that our eyeglasses fogged up. It’s not just annoying but may also pose safety issues because of the temporary blindness.
Fortunately for us, the anti-fog coating is now available.
This lens coating prevents condensation to eliminate the fogging when you make a transition from a cold place to a warm one. What’s more it’s that anti-fog coating will also keep the lenses from fogging up when you are sweating because of physical activities or hot climate.
This type of lens coating can be applied to plastic, polycarbonate and high-index lenses.
UV Protection Coating
Overexposure to ultraviolet light may cause eye cataracts, retinal damage, and other eye problems. Fortunately, plastic lenses can block some of them.
The UV protection coating is another beneficial layer. This is an invisible dye that boosts the capabilities of the lenses to block the harmful lights up to 100%.
This lens coating is usually added for Plano eyeglasses (aesthetic only).
Polycarbonate and high-index lenses don’t require UV protection coating. Photochromic lenses also block 100 percent of the sun’s rays without additional coating.
Blue light blocking lens coatings
Blue light is the bright, artificial light that is produced by LED screens, which are incorporated in most of our modern day digital devices. Blue light blocking lens coating is specifically designed to block blue light and harmful UV rays that disrupt our natural melatonin intake. Essentially, this lens coating acts as a blue light filter that filters out the harmful blue light emitted from your digital devices.
If you, like most of us, spend the majority of your day in front of a screen, consider blue light blocking lens coating to relax your eyes from digital eye strain, also known as computer vision syndrome.
When speaking about lens coatings, it’s good to know that polarization actually differs from other kinds of lens coatings. But what is Polarisation, exactly, and how does it differ from Anti-reflective Coating. Are they the same?
While the anti-reflective coating basically reduces both outdoor and indoor glare and reflection effects at the lens surface, Polarised lenses are primarily for outdoor use. Polarised lenses block highly reflective glare from light reflecting off of flat and smooth surfaces, such as water and road surfaces, better than other types of sunglasses lenses. Anyone who is bothered by the sun’s glare outdoors, such as those participating in watersports, can benefit from polarised lens coating.
Polarising a lens is the process of laminating, or casting, a polarizing film to a lens. A polarised film acts as a filter, blocking out light that bounces off reflective surfaces that is 7 to 10 times brighter than normal daylight.
Polarised coating option comes even for sunglasses with progressive lenses, that is to say a great option for people over 40 who spend significant time outdoors. Moreover, SmartBuyGlasses offers polarised sunglasses with photochromic lenses as well, suitable for those people frequently in and out of the sun in any given day.
