How Transition Lenses Filter Harmful Blue Light

Transition lenses are a type of lens that can adapt to changes in light. They are also known as photochromic lenses, and they have the ability to filter out harmful blue light. These types of lenses were first made available for prescription eyeglasses in 1979 by Transitions Optical, Incorporated.

The lenses of a pair of eyeglasses, known as "transition lenses," are designed to filter out harmful blue light and improve your vision. Transition lenses are perfect for those who want protection from the sun and harmful blue light simultaneously. The way transition lens works are by filtering out the harshness of sunlight while still allowing you to see clearly during sunny days or when there is bright indoor lighting.

What's more, transition lenses will also help protect your eyes from eye strain caused by long hours in front of a computer screen without adequate lighting. Transition lenses are perfect for those who want protection from the sun and harmful blue light simultaneously.


Harmful Blue Light

Blue light is a type of high-energy visible (HEV) light emitted by electronic devices such as cell phones, computers, and tablets. Blue light can be harmful to the eye because it stimulates cells in your retina, resulting in poor sleep patterns, increased glare from screens making them harder to see clearly, or even difficulty focussing on close objects. Also, blue light exposure can lead to age-related macular degeneration (AMD), which can cause blindness.

Wearing transition lenses that filter harmful blue light is an excellent solution because they protect you from the sun and help reduce eye strain caused by long hours in front of a computer screen without adequate lighting. They can also provide you with better sleep and help protect your eyes from other harmful radiation.

The most important thing to remember is that transition lenses have a special coating that helps filter out the blue light before it enters the eye, which can still be harmful even if they are not wearing eyeglasses or sunglasses. This way, they're nothing for the retina to absorb, and it is not as harmful.


Transition Lenses

Transition lenses block 100% of harmful UV rays while still allowing you to see colors clearly. This is because they have a special coating on them that filters harmful blue light. If you wear glasses with transition lenses, they will automatically adjust when transitioning from outside into a building or vice versa. Maintaining healthy eyesight and minimizing eye fatigue are important for everyone. 


Types of Transition Lenses

Transition lenses are available in either a single or double-layer - and these types of lenses generally cost more than traditional eyeglasses because the technology is much newer to be applied. They are available in an array of colors, styles, and shapes, so there is something that suits each person's needs. This includes everything from reading glasses to sports eyewear, and they can be found at any optical store or online retailer that sells eyeglasses.

The best types of transition lenses are those that change from clear to dark on the top outer edge. The outer perimeter of the lens is dark on the top, that when you are looking through these lenses, they do not need to be removed or flipped up for you to see what's in front of you while walking. This type also offers a wider range than just light-to-dark transitions because they can also change from light-to-medium or dark-to-medium.

The most popular type of transition lenses is those that have a clear outer edge and then gradually change to darker shades as you move inward on the lens until it is completely black at the center, which is where your pupil would be located when looking through them.

The most common type of transition lens is Polarized Transition Lenses which have additional UV protection against those who wear contacts or surgery glasses.


Benefits of Transition Lenses

Transition lenses offer a variety of benefits to the wearer, such as protection against ultraviolet rays and adjusting between light sources with ease. They are also easy to clean due to their anti-glare coating, making them great for everyday use. While there are also who believed in the myth about transition lenses, here is the list of scientific benefits you'd get from wearing transition lenses: 

-The primary purpose of transition lenses is to cut down on the amount and intensity of blue light that gets into your retina. When you're outdoors, this type of filtering will help protect your eyesight from UV rays as well as reduce the glare coming off water or snow.

-When you wear transition lenses outdoors at night or indoors in front of a computer screen, they will help relieve eye fatigue and motion sickness by blocking this specific wavelength of light.

-Transition lenses are also made of a different type of plastic that blocks UV rays and keeps the eyes moist by generating moisture from inside the lens to keep it fresh. This is known as hydrophobic or water-resistant material which enables scratches or dirt buildup on these types of glasses to be wiped away easily with just a wet cloth.

-Other benefits of transition lens include increased contract, which improves reading ability and greater depth perception reducing eye strain, contrast, and color enhancement which helps you see better in foggy or cloudy weather.

-Lastly, they also minimize glare from the sun when driving by automatically adjusting to the right tint for that specific lighting situation.


Drawbacks of Transition Lenses

- Transition lenses are a little more expensive than regular glasses, which means that you might have to spend $100-$300 for them.

- The transition lens may not work as well in certain types of weather because it will adjust its tint based on the lighting situation, and if there is not much sunlight, then your eye won't get enough light.

It's important to note that not all eyeglasses come with a transition lens feature. A person who wears prescription glasses can also wear these types of transition lenses, but they will need to have a good understanding of how their eyes react to the different levels so it does not become an issue for them later in life.
