If you’re using Felix Gray glasses or other glasses with anti-glare coating the priority is to prevent your glasses from ever getting scratched.

But 'up' and 'down' are not fixed directions. The vibrations could be vertical, horizontal, or at any angle in between. In fact, the waves that make up sunlight, for example, are evenly distributed across all angles.

Light can be polarised by passing it through a polarising filter. A polarising filter has all its molecules aligned in the same direction. As a result, only waves with vibration aligned in the same direction can pass through.

Disclaimer: Given the anti-glare coating on all Felix Gray glasses, we DO NOT recommend attempting to remove scratches from glasses yourself.

For those who haven’t yet purchased their pair of Felix Gray anti-glare, Blue Light blocking glasses, the below will explain how to get scratches out of glasses. In today’s post, we’ll be covering four of the most common scratch-removal methods and touching on some important points consumers should know about each.

Knowing how to get scratches out of glasses using the above methods can save you a ton of money in the long run by extending the lifespan of your specs. But remember, if these tricks for removing scratches from glasses don’t work for you, you can always consult with an eyewear professional. In some cases, the damage to your glasses may be too severe to repair.

Some animals can see in polarised light, including the fiddler crabs and mantis shrimp in David Attenborough's Life in Colour.

Imagine holding a skipping rope so that it passes between the posts of a picket fence, and waving it up and down. The vertically aligned waves will be able to pass between the gap in the fence posts. But if you wave it from side to side, the waves will be blocked.

Since only a small selection of the waves can pass through a polarising filter, the overall intensity of the light is reduced. This is why sunglasses can be polarised: to reduce brightness and glare without compromising your vision.

Light is also partially polarised when it bounces off a shiny surface. For example, the light that reflects off a horizontal surface, such as a puddle, is mostly horizontally polarised. Polarised sunglasses are usually vertically polarised to reduce the glare from puddles or wet roads.

Light is a transverse wave: the wave is S-shaped, with the curves of the S at right angles to the direction it travels. Essentially, the wave vibrates up and down as it travels forwards.
