One way of dealing with them is getting glasses with blue light protection. One can get themselves a pair by simply looking up “blue light glasses Australia”. Many online stores have great frame options with easy delivery and returns.

Since it is unfortunate that most people are tethered to mobile phones, tablets, laptops,s or computer screens and spend most of their time scrolling and typing away, these glasses provide some respite to the eyes.

What is blue light?

Blue light is essentially light consisting of the shortest wavelengths on the visible spectrum. The shorter the wavelength is, the greater the energy will be. Hence blue light is also called HEV or High energy visible light. Glasses crafted especially to block the blue light have lenses designed to filter or block these HEV light rays.

One may be more aware of the terms “anti-glare” or “anti-reflective” when choosing lenses. These are nothing but the properties of blue light lenses. They reduce the damage caused to the retina by protecting it from exposure to harmful rays for a long time.

Many people are aware of the repercussions of sun exposure on the skin. But little do they know that soaking up in the bright, warm sun can contribute to blue light exposure. Although digital devices do not emit as much HEV light as the sun, the constant exposure and usage have immediate repercussions and have long-term impacts on health.

LED light fittings, which are globally used to reduce power consumption, while environmentally friendly, also emit blue light. Incandescent lights also emit some amount of blue light. Though there seems to be no way out of the situation, blue light glasses provide some amount of relief.

What are blue light glasses?

Blue light glasses have lenses that are specifically made for blocking out a section of wavelengths. They can block about thirty to forty percent of the harmful HEV light rays. They have a pale yellow or green tint that is believed to help infiltration. One can choose lenses that provide up to 445 nanometers of filtration capacity. They also help decrease the strain on the eyes, headaches caused by staring at computer or smartphone screens for prolonged periods.

How can they help?

Artificial blue light can interfere with the natural rising and falling melatonin levels, a hormone that maintains the body’s circadian rhythm, which is commonly known as the sleep cycle. One of the numerous advantages of using these glasses is that they help maintain the optimum level of melatonin in the body. Using these glasses at least three to four hours before bedtime, one can fall asleep faster and ensure one gets enough sleep.

Blue light also increases the level of cortisol, also known as the stress hormone. Like melatonin, maintaining optimum cortisol levels is vital for the health of a person. Blue light glasses help to keep cortisol in check by reducing exposure.

Apart from these two benefits, they also help to avoid macular degeneration. A condition where a specific part of the retina is damaged due to strain and stress on the eyes. Google ‘blue light glasses Australia’ and get a pair now and protect your eyes from the harmful rays!!
