Transitions Lenses

Do you know what is the transition glasses? The transition is very suitable for wearing, and it is becoming more and more accepted by the public. Such as driving, and people who need to walk around indoors and outdoors under sunshine. In short, currently, we have advanced photochromic technology that can darken or brighten lenses in a few seconds (yes, a few seconds!), so they are ideal for everyday wear. The transition lens is also called "photosensitive lens". When manufacturing the lens of the color-changing glasses, in addition to the general raw materials, an appropriate amount of silver halide and copper oxide fine grains should be added. After the lens is made, since the added silver halide and copper oxide have been integrated with the optical glass, the color will change. Glasses can be repeatedly discolored, long-term use, can not only protect the eyes from strong light stimulation, but also play a role in correcting vision. When exposed to strong light for protection, the original transparent and colorless lenses will become colored lenses, so they are suitable for indoor and outdoor use.

You may ask, how does the transitional lens work? When it is exposed to ultraviolet light, the transition lens will instantly darken. Their rate of change will depend on factors such as temperature, time of day and amount of light. The hotter the sun, the faster the lens will darken and the darker the color. Once there is no longer ultraviolet rays, or enter the room, the lens will return to transparency. My god, this is so cool, right? Now, you may start to be interested in transition lenses, and you may want to learn more about transition lenses. It doesn't matter, you will understand when you finish reading this blog.

How Long Do Transition Lenses Work?

The life of transition lenses is as long as a pair of traditional prescription glasses, which is about two years. After about two years of constant wear and tear, you may notice that they are not as bright indoors or outdoors as in the dark. This means it's time for a replacement.

With transition lenses, you will get all the benefits of traditional prescription glasses, as well as built-in UV protection! One pair of glasses, two functions and all-weather convenience. Seriously, it's also great value for money.

Are transition lenses good for the eyes?

Transition lenses (also called photochromic lenses or dimming lenses) are really a great choice (no one) to replace glasses and sunglasses. Please see below for 4 reasons why we need transition lenses.

1.What is the use of transition lenses?

As mentioned earlier, transition lenses are very convenient. Imagine this: you are driving and the sun is shining through the windshield. When you are wearing the transition mirror, you can continue to drive normally without any pressure. The lens will be adjusted according to the light, and it will making it easier for you to see the road, which is better (and safer) than wearing sunglasses.

2.Will the transition block UV rays?

Transition lenses are very effective and can protect your eyes from the harmful ultraviolet rays of the sun. Not only that, they can also be completed in a few seconds. Get out of the house and enjoy the sunshine safely and stylishly. With more advanced dimming technology than ever before, you no longer need to worry about the awkward adjustment period hovering on the lens.

3.Will transition lenses block blue light?

The transition lens can block blue light. Sunlight also contains a lot of blue light. In addition to blocking 100% of UVA and UVB light indoors and outdoors, they can also protect your eyes from harmful blue light caused by long screen time.

4.Are transition lenses suitable for night driving?

You can drive normally by wearing transition glasses at night, because the transition glasses change color according to ultraviolet rays, and the car lights do not have ultraviolet rays, so there is no inconvenience. Whether it is day or night, the transition lens can work normally in sunny conditions, and it can also maintain clarity in dark or dim light.

Color selection of transition lenses

When choosing transition glasses, it is mainly to understand the functional characteristics of their lenses, clearly understand the purpose of the glasses and consider personal needs. Photochromic lenses can also be made in a variety of colors. Currently, the most commonly used transition colors are gray and brown.

It can absorb infrared rays and 98% of ultraviolet rays. The biggest advantage of the gray lens is that it will not change the original color of the scene because of the lens. The biggest satisfaction is that it can reduce the light intensity very effectively. The gray mirror can absorb any color spectrum uniformly, so the scene will only darken without obvious chromatic aberration, showing a real and natural feeling. It belongs to the neutral color family and is suitable for everyone.

Can absorb 100% of ultraviolet rays, brown lenses can filter out a lot of blue light, can improve visual contrast and clarity, and have a brightening effect. Therefore, it is very popular among wearers. Especially when the air is polluted or foggy, the wearing effect is good. It is an ideal choice for drivers.

How to identify the quality of the color changing film?

1. The surface of the high-quality color-changing glasses lens has no scratches, abrasions, rough surfaces, or pits. The lens is obliquely obliquely facing the light, and the finish is extremely high. There are no spots, stones, streaks, bubbles, cracks inside the lens, and the lens is bright and transparent.
2. After the two lenses of the color-changing glasses change color, they must have the same color without any difference. The color change must be uniform, and the discoloration speed and depth of the two lenses are basically the same. There should be no darkening of one lens and lighter discoloration of the other.
3. There is no uncomfortable feeling when wearing, no dizziness or swelling, no blur or deformation of the observed objects.
4. Discoloration speed: high-quality color-changing mirrors have a fast response to the environment. The color changing lens has not reached the maximum color depth after being exposed to the sun for more than 10 minutes, indicating that the quality of the color change is poor. The glasses that have changed color in the sun are moved to a dark place. The lenses that have been rejuvenated for more than 20 minutes are poor color-changing lenses.
5. Protection. High-quality color-changing glasses can block 100% of UVA and UVB, providing the wearer with the most effective UV protection.
