An important article that busts all myths about Anti glare glasses
How can you identify these lenses?
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 reflection 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

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 Reflective vs Anti Glare vs Blue Cut Lenses, which is the best choice?
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 A pair of eyeglasses equipped with simple anti glare lenses should be considered as an outdated product. 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.

What do blue cut lenses have to do with sleep ?

Science says that not all light is equal. Blue light is important for mental alertness. This short wavelength light tells your brain that you do not have to sleep and keeps you awake in day time. In fact in combat submarines that take care of a country’s security, blue light bulbs are used to keep the soldiers awake when they are underwater and in no light conditions. Problem arises when you stare at the screen from close proximity. It causes discomfort and eyes find it difficult to tolerate such light. At night time, the mobile & laptop screen keeps you awake. Some people admit that they can’t understand why they find it difficult to sleep after using mobile & laptop. In scientific terms, your brain stops producing the melatonin sleep hormone which is responsible to make you fall asleep. Blue cut lenses block such high intensity blue light and helps regulating the circadian rhythm also known as sleep-wake cycle.

What about the blue cut lenses price & cost?
Generally the blue cut lens (excluding frame) price falls anywhere between INR 1500 to 2500 but at Zebriana®, you may order the frames equipped with Blue cut anti glare lenses for computer use priced at around INR 2325/- (with frame). This price depends on factors like lens material & lens coating etc. When you buy a pair of these lenses, you actually pay for a strong lens (not necessarily hard) material that won’t break easily and certain optical lens coatings such as Hydrophobic Coating, AR Coating, Anti UV Coating and of course Anti Blue Light Coating. Zebriana® branded computer glasses equipped with blue cut lenses would ensure that you have all those coatings in your lenses and stay there for a longer period of time. As a word of caution, don’t fall in the trap of cheap products. There are sellers in the market who offer glasses with low quality lenses at unrealistically low prices. We have observed that coating of such glasses get peeled off within few days. Moreover, a sudden breakage of lenses while you are wearing the eyeglasses may cause serious injury to the eyes. Hence for your eye safety it is better not to wear the glasses at all rather than wearing a cheap product that does not meet any ophthalmic standard. The best way is to buy those Blue Cut Lenses from an established brand.
