Everything you wanted to know in order to protect your eyes against harsh blue light of computer & smartphones
As the name itself implies Blue Cut Anti Glare Lenses are special ophthalmic lenses that block or filter the high intensity blue light that computer & mobile screens emit. These lenses are incorporated into the ophthalmic frames. This is a multi purpose lens type. Although they are mainly engineered for computer users only but they can be used for other general activities also like playing outdoors, driving etc. This is also a preferred lens type by photo editing professionals. They are also known as Clear Lenses or Blue Block Lenses but the function is same.
Like we explained above that Blue Cut Anti Glare Lenses block the screens rays. Not only they block the rays but also provide slightly improved visual clarity by reducing the dazzling glare of the screen as they also have an anti reflective coating on the surface. Since they have glare reduction quality, this enabled maximum visible light to pass through the lenses. More light transmission simply means better visibility.
There are various brands of Blue Cut Anti Glare Lenses in the ophthalmic market. However only few of them provide a comprehensive solution. Below are some key qualities that an ideal pair of computer glasses must posses:-
✓ Anti Glare Coating – to provide slightly improved optic clarity
✓ Anti Blue Light Coating – to provide defence against blue light
✓ Hydrophobic Coating – to resist water marks on the lens surface
✓ Anti Electromagnetic Coating – to block electromagnetic radiations
There are certain signs that your lenses are genuine Blue Cut Anti Glare Lenses. First of all they will be non colored and the view will be crystal clear. There will also be a shiny layer on front & back surface of the lenses and that shiny layer will appear either green/ blue or yellow when you tilt the lenses. We can not call these lenses are colored ones because it is just a mild shade of the said colors. One of the most popular methods to test these lenses is to use a blue light torch and throw its beam through the lenses. If the beam surpasses then it is not a genuine pair. A real pair would mitigate the intensity of the blue light. However this method is applicable only for non colored lenses. Some lenses require a proper professional lab testing to understand about its efficacy. As a rule of thumb it is best to Buy Blue Cut Anti Glare Lenses from a reputed brand only. For ex: Zebriana (India)
Now this is important. As you are intended to order the glasses with Blue Cut Anti Glare Lenses you must be curious to know what it feels like when you wear those lenses. In terms of the feel, there may be no difference but the view will be slightly improved. Technically the lenses will certainly provide protection against the rays of electronic screens. A cool thing that people around you will notice is the beauty of the lens appearance. They are not like any ordinary non anti glare lenses. In fact your specs will also not reflect back the flash of the camera in a photo-studio and the picture will appear much decent. If you are you night driver then this could be a good choice as these lenses do not lose much light when there is already scarcity of light at night.
Anti Glare Lenses and Anti Reflective lenses are synonymous. If you have to pick one among the two lens types then without any second thought, Blue cut lenses should be your choice. The reason is that Blue Cut Lenses already have an anti glare coating on the lens surface and this helps reduce the dazzling glare of strong light source to some extent. A pair of eyeglasses equipped with simple anti glare lenses should be considered as an outdated product. In most of the ophthalmic lens manufacturing companies have stopped producing simple anti glare lenses as the consumer base is more inclined towards the latest blue cut technology lenses and is a good choice for an average computer user.
Generally the blue cut lens price falls anywhere between INR 1500 to 2500 but at Zebriana, you may order the computer eyeglasses equipped with Blue cut anti glare lenses at around INR 2000 (with frame). As a word of caution there are some sellers offering glasses with low quality lenses at unrealistically low prices. For your eye safety it is best not to wear the glasses rather than wearing a cheap product that does not meet any ophthalmic standard.
Although Blue cut anti glare lenses also provide a significant protection against the strong rays of monitor but the trend is shifting towards a new lens type which has become a darling of IT industry. This new lens type is know as Amber Lens. As per the collection of various reviews and feedback of eyeglasses wearers, people actually feel the difference almost instantly. The cooling effect that amber lenses provide is outstanding. So whether you are a regular computer user who does normal internet surfing or data research or you are a software programmer, amber lens type could be your love.
