Red frame sunglasses aren’t always the only thing that’s red. You can also purchase red lense sunglasses if you prefer a warmer tint to your sunglasses. Contrarty to popular beliefe, red lense sunglasses do not provide more protection from UV rays and cannot keep the sun light from damaging your vision. Red lense sunglasses only change the tinting of the lense and provide no additional benefit. Some people prefer the red tint as it can be relaxing on the eyes rather than a dark tint, and allows them to see certain colors more than others. There are various tints to choose from so the idea is to try them all out and see which you prefer the most.
Red lense sunglasses can be custom made but not at a cheap price. You can spend up to forty dollars to have two lenses tinted with red coloring so this is typically only done with higher end sunglasses. Red lense sunglasses are typically used by hunters or people who spend time in forested areas or by people who are at the lake. This is because they provide an excellent contrast against blue and green backgrounds, allowing the other colors to stand out so that you can view things easier. This is where you will find red lense sunglasses the most useful.
Things to know before buying red sunglasses
You may be here specifically to read about red sunglasses but there are a few things that you should that are specific to all types of sunglasses, red or not. First you will need to have a general understanding of how a few different types of lights work in relation so sunglasses:
Reflected Light: Reflected light is just like what the name suggests. When the sun hits an object and then bounces off of it as it does with water or snow, you are seeing reflected light. This light is not as strong as looking directly at the original ray of light but can still cause damage to your eyes if you look at it for too long.
Direct Light: Direct light is when you view the light from it’s original source directly without any other objects reflecting or filtering the light. If you are wearing your new red sunglasses and look at the sun, this is not direct light as it is being filtered through the red lenses of the sunglasses and is a type of reflected light.
Ambient Light: Ambient light is when you are seeing the light and it is not reflected but not directly from the source. When you are in a room that is dimly lit by a room that has a light on in the room next to it, you are experiencing ambient light.
Basically your when you purchase your nice new red sunglasses they are acting as conditioners of light. That being that they change the effect it has on your retina and how you perceive it. We need this to protect our eyes from damage due to sunlight. The brightness of light is measured in something called lumens. Lumens is how bright the light is that you’re viewing at any specific moment. The higher the number the more chance it has of doing damage to your eyes. You can deal with high lumens by squinting, having pupils that close to not allow in as much light, or by using your hand to shield the light, but if your retina is exposed to high lumens for too long then your eyesight can be damaged.
