With everyday life, there comes a lot of activity and exposure to the elements. Whether you spend the day looking at a screen, outdoors in the sunlight or indoors, there are many things we do daily that put our eyes under stress. That is when Photochromic Lenses can be of use.
There are a lot of glasses out there, that is why it can be hard to find the right ones for you. We at Vision Centre have put together this helpful guide to give you an understanding of everything you may need to know regarding photochromic lenses.
1. What are photochromic lenses?
Photochromic lenses are a type of lens that darken exposure to sunlight and act as a protection for the eyes from UV rays. This is due to them being able to absorb 100% of UVA and UVB rays. They are brilliant for blocking out direct sunlight exposure, which means that the eyes won’t be negatively affected by harmful sun rays.
They can adapt to any environmental changes, making them a comfortable solution for daily wear. They can be available through most prescriptions.
Photochromic lenses are also sometimes known as Light Adaptive or Variable Tint lenses.
2. Why might you need photochromic lenses?
Photochromic lenses are ideal for people who spend lots of time in bright conditions, they help reduce excessive exposure which in effect, helps protect your corneas.
You may be prescribed photochromic lenses as they can combine all of the benefits from your prescription spectacles/contact lenses and the added protection from photochromic lenses.
3. What are the pros of photochromic lenses?
There are many benefits of photochromic lenses. Firstly, they offer great protection from UV rays which will help reduce direct exposure and damage to your eyes. They are perfect for reducing overall eye strain.
They are also very diverse, meaning they can be worn casually, whilst playing a sport or out when out and about. They can be treated with anti-glare, hard coating and water repellent which all will help towards preventing misting.
They are incredibly convenient as they adapt to the lighting around you automatically.
4. Are there any cons of photochromic lenses?
Of course, like with many things – there are a couple of cons. Photochromic lenses are not all the same as there are a variety of brands out there. Depending on the brand, there can be a different adjustment to brightness rates as well as different lightness/darkness degrees.
It is also important to ensure that you pick the right frames for your face. The glasses must wrap around and cover the entire eye. This will help give your eyes full protection as there will be no gaps for UV light to leak through.
Photochromic lenses don’t always work well inside of cars. This is since car glass usually has UV protection which will then prevent the lenses from adjusting.
Sometimes, photochromic lenses can take more time to adjust in much colder climates.
5. How do you keep photochromic lenses clean?
It is recommended that to keep photochromic lenses working at their best, you clean them at least once a day. This helps remove any daily collection of dirt and dust from the spectacles.
Photochromic lenses should be cleaned using lukewarm water. Once they are rinsed, gently shake off the water droplets. When polishing your glasses, they should not be rubbed. Instead, they should be blotted with a micro-fiber optical cloth. This will help reduce any scratching.
