In this article, we will be talking about the technology behind these blue light glasses, how they work, and some of their benefits. There are a number of benefits to using this special type of corrective lens. What I am going to discuss in this article is just a tiny portion of all that this article has to offer.
What’s the Point of Blue Light Corrective Lenses?
This is a question many people often ask when they first get corrective lenses to correct their vision. The answer is actually quite simple. These light glasses actually use very little of your eye’s natural light. Instead, they focus all of the light that hits them on certain colors of the spectrum.
When you look through one of these light blue glasses it looks just like sunlight. In fact, it can be difficult sometimes to tell the difference between sunlight and a pool of water because of the blue light. You might even be able to see your shadow in some conditions. What does this have to do with what do you need to know about blue light glasses?
Two Basic Types
There are ones that are known as the fully comprehensive and then there are limited comprehensive types. The fully comprehensive is the most common type of glasses that people purchase. They are the most complete type that you can purchase. The other type of glasses is the limited comprehensive and these are often used in special situations such as night vision.
Different Types of Light That Normally Hits Your Eye
In order to understand what do you need to know about blue light, you will first need to understand the different types of light that normally hits your eye. Most of us are familiar with the yellow, green, and red lights that are most commonly found in our home. These three colors are the closest thing that we have to natural sunlight. When you use yellow-colored corrective lenses you are actually using a fluorescent light source. This light is much more powerful than what you would typically find in your house but it is also much more expensive.
They Are Safe
They will work in almost all types of situations. However, you do have to make sure that you follow the guidelines set forth by the American Society for Testing and Materials (ASTM) when it comes to purchasing these types of glasses. If you do not follow this guideline, you could end up damaging your eyes while trying to use one of these glasses.
They Are Affordable
You can easily find a pair on sale that are very reasonable. If you spend just a little bit of time looking, you can easily be able to replace some of your present glasses with a pair that is much more durable and that offer better vision than those that you currently have. This is something that any customer should be able to afford.
Excellent for Use
In fact, many people use these glasses to help them see in conditions that are dark or to help them get what they are trying to see. It is in these types of circumstances that you will need to test blue light glasses. When you are trying to see in poor lighting or when you are in an environment where natural sunlight is difficult to find, you should consider using these glasses.
Improves the Quality of Vision for Many People
Basically, a lot of people are able to see better because their eyes are better able to adjust to the light. The problem with this comes from how some light can actually make the eyes feel tired. However, if you have this type of glass in your sight, you will find that it can make the eyes feel refreshed, as well as helping to get rid of the tiredness that often comes when you are trying to see during the day.
Are Blue Light Glasses You Purchase Really Work?
Most people feel great when they get new blue light glasses. They have no concerns at all and are very happy. However, some people may experience some mild discomfort at first and that’s okay because it only lasts a couple of days. After a few weeks, you should begin to see some fantastic results. The results are going to be better than if you were using regular lenses. This is because the lens is more durable and works better for you.
How to test light blue glasses? Many people prefer to have spectrographs to check out how much light they are receiving through their glasses at night. Spectrographs check the amount of pure light received through the material and can measure the percentage of photons that are absorbed, reflected, or transmitted. The only way to really know whether you have the right blue light glasses for night vision, ones which have red or orange lenses, is for the manufacturer to give you a spectrograph report.
If your blue lenses are not blocking 100% of invisible light from between 400, 550 nanometers then don’t buy them or return them within a month.
