A guide to lens coatings

Are coatings on glasses worth it?
ANTI-REFLECTIVE COATING, AR, or Non-Glare

It's a really good idea for indoor use, such as in front of computer screens. It's gonna help considerably in terms of eye strain and eye fatigue. If you are gonna use these at night it's going to be fantastic at cutting the halos around headlights just giving you better optics. Overall it helps to cut glare bouncing off of the lens which means you're getting more of that light that you need to see actually making it to your eyes. A  fantastic idea for your clear lenses and your transitions lenses is almost an absolute must if we're talking about sunglasses, it's a really good idea on the backside of the lens because it helps to minimize glare and reflections bouncing off the backside overall this is a really good lens feature to include in your glasses. 

SCRATCH-RESISTANT COATING

One of the primary concerns with prescription lenses is are these going to scratch? 

These are scratch-proof with scratch-resistant coatings, which helps to make these lenses last longer. But because nothing is scratch-proof you will need to still be careful with how you treat your glasses like sunglass always stays on your face or in the case that way you don't have to replace but these scratch coatings can help give you a little more peace of mind as they come with a good scratch warranty. This means it can be replaced for you if the scratch is not too deep usually one time but at no cost to you. So this can be a really good feature to consider when you're looking at a pair of glasses for you. 

UV COATING

Is UV coating necessary on glasses?

UV is something that will either be inherent in the lens or it will be a lens feature to add as a dye like a CR 39 lens which supporter X doesn't work with. Always ask your optician to make sure your lenses are UV coated because it is super imported. However, there are some coatings that have UV included in them and there are anti-reflective coatings that have a UV element to them, and while it makes you wonder what's the point of a UV coating on the outside of the lens where the lens itself blocks UV. Well, that's where the anti-reflective coating comes in because it's on the backside of a sunglass lens and you have light bouncing off of the backside of the lens. Well, that light is reflected light and therefore not passing through the lens and therefore not getting that UV protection that the lens handles. You will get that benefit of the anti-reflective coating that blocks that UV light on reflected light.

MIRROR COATING

Mirror coatings are an excellent feature for sunglasses because it helps to make for the darkest lens possible. The mirror coating helps to reflect more light back which means less light is making it through the lens into your eyes effectively giving you a darker lens. So, if you are looking for the darkest lens possible or for a little more customizability. If you want something that put your personality into your sunglasses a mirror coating is cool because you can select the lens colour and you can select the density of that mirror whether it be really bold or a little more subtle.

ANTI-FOG COATING

This is a coating that can be really important for certain setups especially snow goggles that by the way splitter X makes inserts for but also high rap frames can be a good idea or frames with gaskets and those tight seals like you get from Wiley X.
