Different Types Of Lenses With Different Functions
It is both the frames and the lenses that come together to make a beautiful pair of spectacles. There is no room to compromise on either of the two, if you really desire to keep your style game on point.
When it comes to eyesight correction, the frames play an indirect role such as ensuring that your glasses fit you well – one of the prerequisites for a perfect vision. But, it is the lenses that utilise the scientific concepts of light and are mainly responsible for providing eyesight correction.
However, the utility of glasses these days is not only limited to being an eyesight correction instrument and a fashion accessory, but goes much beyond that. And this is achieved by using lenses of different types, each type performing one or even multiple functions. Let’s discuss them in detail.
For those who require an eyesight correction for certain conditions such as nearsightedness or farsightedness, among others, lenses fitted with prescriptions are used.
The measure of power of your eyes, when there is a need for an eyesight correction, is referred to as prescription. Prescription glasses are much needed for your vision. You can buy these vision glasses online, as a huge collection is available here at prices that are very affordable.
If you are someone who wears glasses, you must have experienced glare at some point in your life, especially if you are involved in activities like cycling, driving, skiing, etc. Glare is caused when light hits the surface of the lenses and bounces back.
By applying an anti-glare coating, which is also known as anti-reflective coating, light rays don’t get reflected off the surface of the lenses and glare is eliminated. You can get an anti-reflective coating applied, if the lenses of your glasses are reflective and cause glare.
Blue Light Lenses
To ensure that the increasing screen time doesn’t take a toll on the health of your eyes, you should put on a pair of blue light blocking glasses whenever you face a digital screen.
Keeping your eyes fixed on digital screens for a long duration can result in conditions like eyestrains, headaches, fatigue, and related issues. The blue light lenses use a blue light filter to cut down the amount of blue light striking your eyes by a significant scale.
UV Protective Lenses
Yes, we are talking about the highly fashionable sunglasses. The lenses of sunglasses are coated with UV protective coating, which serves the specialised function of blocking the harmful UV rays of the sun.
While buying your pair of sunglasses, keep a check that you choose a pair that provides both UVA and UVB protection. This will result in almost 100% UV protection.
These lenses undergo a change in the colour of their tints, as per the intensity of light falling over their surface. When you stay indoors, they continue to remain clear and as and when you move outdoors, the clear lenses undergo a change in their tint colour to provide the function of a pair of sunglasses.
You no longer need to carry two separate pairs of spectacles if your day involves continuously shifting between indoor and outdoor spaces. You just need one pair of magical glasses, magical owing to the transition lenses.
If you are in need of any of these lenses, go ahead. You can also get them upgraded by sending your glasses for reglazing. If you prefer the online mode of shopping, next day delivery of glasses is also possible, with same day glasses around.
