Blue Light Glasses Protect You From the Trap of Harmful Blue Light

How much time do you spend daily on your laptop or computer? And what about your smartphones, how often do you use them? Do you experience any headache or pain and redness in the eyes? Then you are being chased, trapped and affected by the blue light. This blue light is neither discovery nor a newly developed ray. It has well existed as long as the sun exists in the universe, only its harmful effects were not brought into the light so far.

What Is Blue Light?

Let us understand what exactly this blue light is. Blue light is the short wavelength rays present in the visible spectrum. The wavelength of blue light is between 380 nm and 500 nm, which makes it shorter in the electromagnetic spectrum. The shorter the wavelength, the higher will be the energy level. Due to its short wavelength, it is visible to the naked eyes as well. Interestingly, it is part of the natural source of light on the earth. By this, it means, blue light is present in the sunlight and is scattered everywhere during the day on the planet. Besides, the blue light is responsible for making the sky appear blue to the eyes. Thus, it can be said that blue light is present everywhere around the globe. With sunlight comes the blue light.

Apart from the sun, there are other man-made and artificial sources of blue light emission. These sources include LED lightning, fluorescent lights, digital screen devices (such as LED devices, television, computers, laptops, smartphones, tablets, etc.) and other such electronic products. These devices emit blue light irrespective of day and night.

Positive and Negative Effects of Blue Light

Blue light is not always harmful. It has its advantages as well. Although the list of advantages is limited, the disadvantages are more harmful. As far as the benefits are concerned, blue light helps in keeping us awake during the day time. This happens because of the secretion of Melatonin Hormone in the body. During day time or whenever the blue light is exposed, the pituitary gland of the body reduces the secretion of Melatonin hormone. The lower quantity of Melatonin hormone keeps us awake and alert. On the other hand, in the absence of blue light or the dark, the production of Melatonin hormone is increased and is secreted in higher quantities. The risen levels of melatonin hormones help the body in falling asleep as well as promote sound sleep. This sleeping and awake cycle is called the circadian rhythm. The melatonin hormone responds not only to the blue light present in sunlight but also to the other artificial sources of blue light such as smartphones, laptops, computers, Xbox games, etc.

However, when after the sunlight, artificial lights and other digital devices emit blue light, our body gets confused. The body responds to the blue light, irrespective of the day or night time. Thus, even after dusk, the Melatonin reduction is suppressed as the brain is under the impression that the availability of blue light is due to the day time. Thus, the brain triggers the body to keep awake. Hence, the blue light disturbs the circadian rhythm and leads to the cause of insomnia and disrupted sleep.

Moreover, the regular and extended use of digital devices leads to continuous exposure of blue light to the human eyes. The eyes are sensitive and the natural lens of the eyes is unable to filter the blue light. Therefore, the blue light travels as far as the retina in the eyes. The retina is made up of very fine tissues which cover the inner ball of the eyes. Therefore, the blue light can cause regular irritation in the eyes such as pain, redness, dry or watery eyes, itching, stress, and strain. However, in severe cases, the blue light from the digital screen can lead to macular degeneration, glaucoma and retinal destruction. The blue light exposure also gives rise to a digital migraine that is the occurrence of headaches due to the continuous use of digital screen devices.

Protect Your Eyes With Blue Light Glasses

The best solution to keep away and prevent blue light is to use blue light glasses. These glasses are just like your regular glasses including prescription glasses for distance and reading. The only specialty is that the glass lens contains a protection feature which blocks the blue light from entering the eyes. These glasses are capable of filtering up to 99.9 % of the blue light and preventing them from further damaging the eyes or the retina. They are also known as blue light blocking glasses, anti-blue light glasses or the X-blue light glasses. Just like the anti-UV glasses block the Ultraviolet rays, similarly, anti-blue light glasses block harmful blue light. However, the colour of the glass lens remains unaffected and there is no change of colour or discolouration of the lenses. However, in some glasses, a light tint of blue or green hues may appear on the lenses, otherwise, they are normally clear and transparent.

Prescription or Non-Prescription Glasses With Blue Light Blocking

Moreover, blue light blocking glasses can be prescription or non-prescription glasses. Since many people work on laptops and computers daily at work for long hours, say around 8 to 10 hours minimum. Thus, even if they do not wear prescription glasses, they can have blue light glasses without any power strength lenses. Such glasses are not meant to correct refractive disorders of eyes but are meant to prevent eyes while using digital screen devices. Owing to this property, blue light blocking glasses are also called computer glasses, as people wear it while using a laptop, or computer.

Blue Light Blocking Fashion Glasses

This does not mean that the blue light blocking glasses need to be boring, and dull-looking. Blue light blocking glasses can be crafted in any fashion glasses be it of any colour, shape, size, rim-type, materials, branded designer, prints, frame thickness, or style. As long as they keep eyes protected and contain blue light blocking properties on the lenses, fashion glasses are worth it. To look stylish, classy, bold and elegant, buy glasses online with blue light blocking properties.

Reglaze Glasses – An Effective Measure to Use Old Frames With New Lenses

In case your existing glasses are lacking blue light blocking properties, then you can reglaze glasses. Under this technique, the old lenses are removed from the frame and new lenses with customisation are added to the frame. The new lenses consist of blue light blocking properties. Thus, without changing the current frames, you can easily convert them to blue light blocking glasses through the process of reglaze glasses. This is also a cost-effective way of using your old frames while giving a new life to them.
