If you wear glasses, you're probably familiar with transition lenses. These
lenses are designed to automatically adjust to changing light conditions,
getting darker in bright sunlight and lighter indoors. This makes them a great
option for people who don't want to switch between different pairs of glasses
throughout the day.
However, if you're new to transition lenses, you might be wondering how to activate them. In this blog, we'll explore different ways to activate transition lenses and answer some common questions about how they work.
What triggers transition glasses?
Transition lenses are activated by UV light. When the lenses are exposed to UV light, a chemical reaction occurs that causes them to darken. This is why transition lenses are often referred to as photochromic lenses. The amount of UV light needed to activate the lenses varies depending on the type of lens, but in general, they will start to darken when exposed to sunlight.
How do I activate transition lenses?There are a few different ways to activate transition lenses:
- Go outside: As we mentioned earlier, transition lenses are activated by UV light. The easiest way to activate them is to go outside on a sunny day. As soon as the lenses are exposed to UV light, they will start to darken. It's important to note that transition lenses don't work as well in cars because the windshield blocks a significant amount of UV light.
- Use a UV flashlight: If you don't want to wait for a sunny day, you can use a UV flashlight to activate your transition lenses. UV flashlights emit UV light, which will cause the lenses to darken. You can find UV flashlights online or at your local hardware store.
- Use a UV lamp: Another option is to use a UV lamp to activate your transition lenses. UV lamps are often used in tanning beds and can emit enough UV light to activate the lenses. However, you should be careful not to expose your skin to too much UV light, as it can be harmful.
- Wait for them to adjust: If you're patient, you can simply wait for your transition lenses to adjust to the light. It can take a few minutes for the lenses to darken in bright sunlight, but they will eventually adjust on their own. Similarly, when you go back indoors, the lenses will gradually lighten up.
What are some common misconceptions about transition lenses?There are a few common misconceptions about transition lenses that we'd like to clear up:
- They don't work in cars: As we mentioned earlier, transition lenses don't work as well in cars because the windshield blocks a significant amount of UV light. However, some newer cars have windshields that allow more UV light to pass through, which can activate the lenses.
- They don't work in cold temperatures: Some people believe that transition lenses won't darken in cold temperatures. While it's true that extreme cold can affect the lenses' performance, they should still darken in most normal temperature conditions.
- They always get very dark: Transition lenses are designed to adjust to changing light conditions, so they won't always get very dark. The amount of darkening depends on the amount of UV light present. If you're in an area with low UV light, your lenses won't get as dark as they would in bright sunlight.
- They might not be suitable for everyone: While transition lenses are available in a variety of prescriptions, they may not be suitable for everyone. It's important to consult with your eye doctor before getting transition lenses.
Are there any downsides to transition lenses?While transition lenses are a great option for many people, there are a few downsides to consider:
- They can be more expensive: Transition lenses are generally more expensive than regular lenses, so they may not be the best choice if you're on a tight budget.
- They don't always work quickly: If you're going from a dark environment to a bright one, it can take a few minutes for the lenses to fully adjust. This can be frustrating if you need to see clearly right away.
- They may not get as dark as you'd like: If you spend a lot of time outdoors in very bright sunlight, you may find that your transition lenses don't get as dark as you'd like. In this case, you may need to consider getting a separate pair of sunglasses.
- They may not work for everyone: As we mentioned earlier, not everyone is a good candidate for transition lenses. If you have certain eye conditions or take certain medications, your eye doctor may recommend against using transition lenses.
In conclusion, transition lenses are a great option for many people who want
to simplify their eyewear and not have to constantly switch between glasses.
They are activated by UV light and can be activated by going outside, using a
UV flashlight or lamp, or simply waiting for them to adjust.
