Moving past their conventional functions of eyesight correction or serving as an ideal fashion accessory, glasses have come to serve a lot of other functions today. This is done by customising the lenses in different ways to serve the required functions. Last week, while looking for a pair of designer glasses online, I was amazed by the number of customisations that were offered for the lenses. To avoid confusion, I am here to guide you.
Here are the different types of lenses that you must know to make an informed purchase. It is to be noted that a pair of lenses when fitted to a frame can even serve any one of the functions mentioned below or even more than one.
These lenses use a thin protective coating, which eliminates the reflections from both the front and back surfaces of your lenses. These reflections cause hindrance in clarity of vision.
Glare is mainly encountered during activities like driving and cycling, working in bright sunny conditions, or even in snowy areas. It is a result of light reflected from various obstacles on the ground. Applying an anti-glare coating on your lenses is highly recommended for a clarity in vision.
To sustain your reading for a longer time duration, reading glasses are your go to option. Not being able to read the small texts or texts becoming blurry after reading for some time, are some of the common problems faced by readers, especially as one grows older.
The lenses used in reading glasses magnify these texts, reducing the stress on your eyes by a considerable level. You can also get your prescription fitted into these reading glasses.
UV Protective Lenses
There is no way you can hide from the harmful UV rays of the sun, as they are everywhere. But what you can do is take precautions. This is where the role of UV protective lenses come in.
Your sunglasses are nothing but UV protective coating applied on clear lenses. These lenses are very effective in blocking the harmful UV rays. A good pair of sunglasses is one that provides both UVA and UVB protection, as this reduces the exposure to UV rays to negligible levels.
Blue Light Blocking Lenses
Blue light – in excessive amounts – can be harmful for your eyes. Also, you need to avoid exposure in dim light conditions. In the above-mentioned scenarios, blue light might result in conditions like eye strain, blurred vision, dry eyes, etc.
Digital screens are one of the major artificial sources of blue light. Considering our increase in screen time, against the backdrop of COVID-19 pandemic, blue light blocking glasses have become very necessary. These glasses cut down the amount of blue light striking our eyes to negligible levels.
Transition lenses make it possible to have sunglasses and your normal clear glasses – both prescription and non-prescription – in a single pair. When the intensity of light falling on the surface of transition lenses changes, the inbuilt mechanism automatically changes the colour of their tints. If it is required for you to continuously shift between indoor and outdoor spaces, then transition lenses may just be a perfect option for you.
Are you in need of any of the above lenses? If yes, you can buy eyeglasses online to avail them at affordable prices. There are also amazing services offered over the online medium such as the same day glasses. Same day glasses service makes it possible for you to get your glasses next day of placing the order.
