Most glasses wearers face one common problem in summers – switching between specs and shades. While some put up with the hassles, some find an easier alternative, say transition glasses. But, they often doubt the effectiveness of these glasses.
If you are also on the fence about the benefits of these glasses, you’ll find answers to all your questions in this blog. Just keep reading to know what these glasses can actually do.
What are transition glasses?
Transition glasses have photochromic lenses. The deal with these glasses is that the lenses change colour and darken up in the presence of UV light.
These are just like your regular glasses that turn to sunglasses when exposed to UV light. The lenses assume a tint that protects your eyes from UV damage and provide better visibility in bright light conditions.
How do transition glasses work?
These glasses are made by photochromic technology. The surface of these lenses has trillions of photochromic molecules that react to UV exposure by changing their structure.
These molecules are almost invisible and clear until they come in contact with sunlight or UV. When you step out in the sun, these molecules move and change shape to effectively absorb the light and allow only good light to penetrate your eyes. This process causes the lenses to darken and turn into sunglasses.
Should we use transition glasses?
Now that you know what transition lenses are and how they work, let’s address a big concern – are these lenses safe to use? Well, the answer depends on the quality of these lenses.
As transition glasses have become a topic of discussion among people, many eyewear companies are cashing in on this trend. But, not all of them are offering the best quality. When you buy these glasses, make sure you check the quality and buy only from a reputed brand.
If the lenses don’t transition quickly when you step from indoors to outdoors or vice versa, then they won’t offer you the best sun protection.
Benefits of transition lenses
A good pair of transition glasses can give you the following benefits:
- They can prevent eye strain from blue light. exposure
- They offer continuous protection from UV rays.
- They are easy to use and can be worn both outdoors and indoors.
- You are able to see better in bright light environments
- These glasses can reduce glare as well
- You can wear them when driving in the daylight so your eyes are not bothered by sunlight glare.
Before you buy these glasses
Another question that pings our heads is when or how to decide that you need photochromic lenses?
Consulting your eye doctor about the right type of glasses is the best way to decide what will work for you. It will take some time and advice but it will be worth it.
If you have your heart set on these glasses, make sure you buy only high-quality transition glasses. Specscart is a British eyewear brand that offers top-quality transition lenses that change colour within seconds.
How long do these lenses last?
The durability of these lenses depends on how much you take care of your glasses. If the lenses get scratched or damaged, then it will affect the photochromic molecules embedded in them and you might not get the best UV protection.
Your transition lenses should last for two years. You will need to change your glasses as soon as your eye prescription changes.
Here are some important things you must know about these lenses:
- They may take longer to change colour in cold weather
- They won’t change colour when you are inside a car as the windshields already filter out the UV light
- Depending on the colour of the tint, these lenses provide different uses. For instance, brown tints provide better visual contrast and help you see things in detail
Buying transition glasses to get the benefits of both spectacles and sunglasses is a good idea. Make sure you read the label and buy glasses that are able to filter out 100% UV400.
