Lenses available on the market today are a true testament to the technological advancements we have made in eye care in the modern era. From an abundance of options regarding frames and colours to customizable corrective capacities of glasses, we have come a long way. Due to the highly customized needs of different consumers, retailers have introduced lenses with various features and filters that can protect your eyes in addition to having their existing prescription.
The fundamental reason most people invest in the best eyewear is that they seek to have a complete solution to their corrective and protective requirements. Exposure to UV radiation glares and blue light from screens constantly causes deterioration of our visual acuity. That is why eyewear today seeks to combat all environmental factors to keep our eyes healthy for the long run. This pursuit has led to the introduction of photochromic lenses, the perfect example of modern utility in eyewear. Installing these lenses can turn your glasses into prescription sunglasses, eliminating the need to invest in two separate pairs of glasses. Therefore, here is a beginner’s guide to buying photochromic lenses.
Photochromic Lenses: The Basics
The inception of the photochromic lenses, like every other invention, was one out of necessity. Many people who struggle with prescription eyeglasses often have trouble alternating between their glasses and sunglasses when outdoors. Standard eyeglasses do not offer UV protection, but if they come with photochromic lenses, they can turn into tinted sunglasses as soon as you enter the sun.
On exposure to sunlight, a photochromic lens turns from a clear lens to a dark tinted lens within 30 seconds. They are designed to react to the external stimulus of sunlight, which is why they are often referred to as react lights. These photochromic lenses may differ across brands and are mostly available in glass, polycarbonate, or glass.
What makes them change colour?
The photochromic lenses and their function are built on the same elements present within the lens’s structure. The lens is synthesized with molecules of silver halide, which on exposure to the sun, undergo a chemical reaction which causes the lens to change in colour. The chemical reaction catalysed by the sunlight causes the molecules of silver halide within the lens to expand in size and change their orientation. The tint of the lenses is not permanent, as it returns to clear within 15 minutes of you returning indoors or to a place with limited sunlight.
Why Photochromatic Lenses make Great Prescription Sunglasses
The benefits of photochromic lenses are reason enough to switch over to these stylish and functional lenses. They are designed to make your life easier, being an understated modern marvel, you can have them as an accessory to your busy days and sunny plans. Here are some reasons why they make great prescription sunglasses that you can invest in for your next eyewear pick:
Dual-Solution in One Cost: The cost and maintenance needed with two separate pieces of eyewear are always more tedious than one pair that offers a solution to all your requirements. These adaptive lenses make your existing prescription eyeglasses capable of automatically becoming sunglasses whenever exposed to UV radiation. While installing photochromic lenses may be costlier than regular lenses, it is more cost-effective than buying two glasses for two different purposes.
Eye Protection: Glasses with photochromic lenses are prescription sunglasses which can do the same job a pair of sunglasses can. The wearer’s line of sight remains clear and comfortable as soon as they step outdoors. It is crucial to protect the eyes from the sun as it can cause problems in the future. That is, photochromic lenses make the ideal protective eyeglasses.
Convenience: Investing in photochromic lenses will eliminate the need to carry and maintain two glasses. You will need to leave the house with only your eyeglasses with photochromic lenses, which can double as prescription sunglasses whenever you are in the sun.
Eye Health: Long-term exposure to sunlight and UV radiation can exacerbate existing eye problems and cause rapid deterioration of your eye muscles. That is why investing in photochromic eyeglasses keeps your eyes protected no matter your environment and keeps them healthier in the long run.
The function of photochromic lenses is to make your life easier and save on extra costs when it comes to protective eyewear. Titan Eyeplus and their range of stylish eyeglasses offer customizable options for lenses where you can add photochromic lenses to your prescription eyewear for added convenience at a reasonable cost.
