There’s a problem that’s worked it’s way into our hyper-connected society called “decision paralysis”. The problem, at its core, is this: when a person is presented with too many different options, and not enough information, they become incapable of making a choice. This seems counterintuitive – the more options you have, the more freedom you should have, but you can’t really feel free when you find yourself incapable of deciding. We don’t want shopping for glasses to feel this way, so here we present you with four different lens coatings, and enough information that it’s easy to decide whether or not the coatings are right for you.
Anti-Reflective (AR) Coating
AR (sometimes called anti-glare) coating has become a staple of modern eyewear. The coating allows the maximum amount of light to enter through the lenses. This has two main benefits. More light passing through the lens means less light is reflected; reflected light creates glare, which can obscure vision. This means AR lenses are particularly well suited for people who drive and night, as well as people who use computers often – in short, they’re well suited to pretty much everyone. The second advantage of AR coating is that it’s easier to see your eyes; less glare for you means less glare for everyone looking at you, too. There is a slight disadvantage to AR coatings; the lenses tend to smudge a bit more easily than non-AR lenses. The coating can also peel over time; there will usually be some warranty against this.
Scratch Resistant Coating
This is another “must have” coating; lenses can scratch pretty easily, as most longtime wearers can attest to. You need to be careful when you’re cleaning your glasses to avoid causing them damage, and accidents happen. Scratch resistant coatings don’t make your glasses scratch proof, but they do give them a much harder surface, which will make them stand up better to abrasion.
UV light can cause damage to the eyes, and seem to be implicated in the development of cataracts. UV coatings can block 100% of the UV rays that pass through them, but that doesn’t mean light can’t reach your eyes from other direction; wrap-around lenses with UV protection are the best way of reducing exposure to UV rays while you’re outside. These coatings are clear, but are also available on sunglasses.
Applied to sunglasses, mirror coatings are basically the opposite of UV coatings; they make it so the lenses reflect a lot of light. There are a couple of potential advantages to this. The first is that mirrored lenses make it impossible to see your eyes, which can have aesthetic and practical advantages. The second is that mirrored lenses actually provide significant reduction in glare, making them great for snowboarding or surfing.
Your Winnipeg optometrist can apply any and all of these coatings to your glasses; aside from mirrored coatings, most come highly recommended for pretty much anyone – there’s no real disadvantage to reducing glare, protecting your eyes from the sun, and being more durable.
