After selecting your lenses, it is time for you to think about what kind of coatings will fit you well. There are 5 kinds of coatings with different functions to satisfy your needs.
Anti-Scratch
Plastic lenses are usually lighter and more comfortable than glass lenses, but they’re also easier to have abrasions and scratches. Even with our anti-scratch coating, it doesn’t mean that your lenses will not scratch at all. Please remember that even the best anti-scratch coating can’t 100% protect your lenses from wear and tear. To prolong lens life, please put them in your case when not in use, and clean your lenses regularly with cleaning cloth.
Anti-Static
Static electricity sometimes can be really annoying, especially in dry or dusty environment, because dust and dirt can cling to the lenses and blur your vision. The anti-static coating repels dust and dirt, and keeps lenses cleaner. Since it can keep debris from sticking to lenses, the anti-static coating makes it easier to clean.
Anti-Reflective
Anti-reflective coating (also known as “anti-glare coating” or AR coating) helps improve vision and reduce eye strain by eliminating reflections from both sides of the lenses. Different colors make your eyeglasses look more attractive. AR coating is especially recommended for high-index lenses because high-index lenses reflect more light than standard plastic lenses. The advantage of AR coating is also obvious at night when it makes your lenses almost invisible, so that you can have better eye contact with people and can see more clearly.
UV Protection
Not only does our skin need sunscreen, our eyes also require protection from sun exposure. Harmful UV radiation may cause age-related eye problems and diseases. The UV protection coating is like the “sunscreen” for our eyes, minimising the damage from the sun. Professional sunglasses are recommended to use since childhood. Most lenses have 100% UV protection built-in.
Blue Light Blocking
Research has shown that prolonged exposure of “High Energy Visible” (HEV) blue light can cause eye strain and blurred vision. Eye diseases including glaucoma, retinal degenerative problems, macular degeneration can be expected during excessive exposure of harmful blue light for a long time. Artificial blue light mainly comes from computers, cell phones, LED lights and other digital devices, causing eye fatigue without your notice. We spend almost half of every day using our devices: our computers at work, our TVs at home, and our tablets and smartphones anywhere and everywhere in between. Got one to protect your eyes!
Do blue light glasses really work?
What is Blue Light?
Contrary to UV light, blue light is emitted all around us, every day — both indoors and outdoors, from the screens on our digital devices to the sun as the biggest source. Extended exposure to certain wavelengths may cause eye fatigue and discomfort, but don’t worry! Our blue light filtering glasses and computer screen glasses can reduce your exposure to potentially harmful blue light. Learn how to choose the best lenses for blue light prescription glasses.
How Does Blue Light Affect Us?
Our constant connection to our smartphones, tablets, and laptops may contribute to headaches, sore eyes, and stiff necks — all symptoms of digital eye strain. With the majority of our waking hours spent in front of a screen, paired with harmful blue-violet light* from digital devices, it’s no surprise that our eyes are working harder than ever.
*Disclaimer: Harmful blue-violet light is between 415-455nm.
If you’ve ever worried about the effect of digital screens on your eyes, then you may have heard about ‘blue light’, and perhaps even searched for ways to protect your eyes against it. Blue light glasses (or blue light blocking glasses) are becoming more popular than ever due to claims that they can protect your eyes against potential damage — but how effective are they at keeping your eyes healthy? Here, we’ll take a closer look into the scientific research behind blue light glasses, and whether they actually work.
Protect Your Eyes with Blue Light Filtering Glasses
Both our non-prescription and prescription blue light filtering glasses and prescription computer glasses are designed to protect your eyes from extended exposure to harmful blue-violet light. Whether you’re wearing them for gaming, working into the wee hours of the night, or binge-watching your favourite show, blue light filtering glasses and glasses for computer use are the way to go.
LENS COATINGS FOR MORE VISUAL COMFORT
Lens coatings, also known as lens upgrades, are an excellent way to improve your visual comfort and acuity by making your lenses even more reliable. Lens coatings, which are an essential component of your prescription lenses, use some of the most advanced technology to ensure safe vision. Lens coatings will provide additional protection for your eyes as new problems emerge, such as the harmful effects of UV and Blue-Violet light on your eye health(1). Although your prescription lenses will help you see better, using a lens coating will support your eye health while also improving your acuity and comfort. With that in mind, let ‘s look at some of the most effective lens coatings on the market.
LENS COATINGS THAT ARE ANTI-REFLECTIVE AND ANTI-SMUDGE
Reflections and smudges are two of the most inconvenient elements of wearing glasses. Both can impair your vision and make you feel uncomfortable. An optical lens is designed to
refract light to correct your vision, and light will often reflect in some way due to the existence of an optical lens surface. We are surrounded by reflections as the number of artificial light sources increases. Light enters the spectacles from all directions, causing reflections. These thoughts can cause anxiety and have an effect on your daily life. This causes us to change our actions, both consciously and unconsciously. To cope with reflections, some people shift their head orientation, change their stance, and even remove their lenses. Anti-reflective lens coatings are an excellent solution for such issues. Lens improvements with anti-reflection or anti-glare properties are ideal for increasing visual acuity. Similarly, smudges can be quite distracting and hard to analyze. Lens coatings can actually shield your lenses through repelling smudges and avoiding scratches. Crizal Sapphire Ultra violet is indeed a lens coating that offers best-in-class clarity for improved vision and aesthetics. Crizal Sapphire Ultra violet could provide fewer distractions while using your lenses by reducing the amount of reflections. The lens becomes enhanced visually so that it appears transparent to others; this is ideal for easy, day-to-day activities such as conversing with others. Your lenses can repel water droplets, dust particles, scratches, and smudges when combined with Crizal Sapphire UV. Your new lens upgrade enhances your daily life by offering visual clarity and easy-to-clean, protected lenses.
COATINGS FOR UV PROTECTIVE LENSES
You can help your eye health by mixing the right lens enhancement with your lenses. UV defence has been shown in recent years to be an important part of maintaining healthy vision. UV safety lens coatings are a valuable and essential addition to your lenses. Crizal Prevencia will provide protection from all types of harmful light, including UV and Blue-Violet light. Crizal Prevencia has the best E-SPF index for clear lenses, with a rating of 35. (2). UV protection on your lenses will help to avoid premature ageing and lower your chances of developing cataracts (3). This can help to preserve visual acuity and comfort.
CAN LENS COATINGS BE USED ON CHILDREN?
If your child wants glasses to see better, you should think about lens enhancement. They not only have a protective shield to extend the life of the lenses, but they are as beneficial to children as they are to adults. A lens coating can benefit children, particularly when they begin school. This is due to the fact that coatings like Crizal Sapphire UV remove distracting reflections, which could impair their vision and therefore their learning. Furthermore, children’s eyes are more vulnerable to the combined effects of UV light, so any additional protection you can provide them is a huge benefit.
