Glasses to block blue light: Clear solutions to unclear problems
If you look at the trends in spectacles and its lenses over the last couple of years, you will see an upwards increase and demand to purchase glasses to block blue light. What are blue light glasses, you ask? Well, as you will see all around you that people are increasingly hooked on their mobile phones. You go to the office and you find people spending most of the time in front of a screen, rubbing their eyes from time to time. You come home and watch TV for entertainment and spend scrolling time scrolling through the social feed on your smartphone; you might find that the light emanating from the screen is irritating your eyes. That is the ‘blue light’ which is irritating your eyes and it is one of the most harmful by-products of innovation in technology.
Let us talk about the procedures you can follow to avoid harm to your eyes from the blue light. Firstly, you need to take frequent gaps whenever possible and just go away from the digital screen. You do not know how long you have stared at the screen, you do not even know if you have blinked for the last few minutes too. You are just sometimes thinking or working, right in front of a screen and staring at it; not knowing the level of harm it is causing on your eyes, completely unaware. You should take a gap and look as far away as possible and try to focus on an object, not a digital screen(make sure of that). You need to do that for half a minute almost and then get back to work.
How harmful is the blue light?
The light coming out of the screen might even cause you headaches and strain your eyes to the level that you start squinting them. There also comes an option in smartphones and laptops to equip a mode which does not emit so much light and does not harm your eyes that much. Heavy exposure for a number of years might even cause irreparable damage to the retina; you better take it seriously and take better care of yourself.
How can blue light glasses help you?
Go to any eyewear brand such as Specscart and type in a search for ‘blue light glasses’. You will find that the glasses are available for prescribed and reading both. The lens comes with a slight tint of colour to it so that you know the glasses to block blue light are authentic and original. You can check the lens by passing a laser through it; if the light doesn’t pass then the originality of the product is established.
There is another option if you just made a purchase for frames and do not want to change it. You can look for options such as reglazing glasses and getting the lens changed by an optician or optometrist. Reglazing glasses means that the professional would get a new pair lens into your old frame and take care of both the needs; you get your old frame and now they can be used as glasses to block blue light.
As a fellow wearer of glasses and someone who spends most of the time working on a laptop or on a smartphone(yes, I tick all the boxes), the blue light emitting from the screens will cause you harm. You might not have noticed it yet, but the technology today and our needs have made it so to require a product like blue light glasses. No two ways about it. Read about the phenomena and take better care of yourself.
