BrainMarket Greenhorn - glasses blocking 100% of blue and green light

Glasses blocking 100% of blue and green light, Greenhorn

Glasses suitable for wearing 1.5 - 2 hours before sleep to block blue and green light and optimize circadian rhythm. They can block up to 100% of harmful blue and green light. They block the spectrum with a wavelength of 390 to 565 nm. Elegant unisex design with black frames.

This is a certified product, approved by the European Union as blue and green light blocking glasses.

The glasses are packed in a plastic bag and cardboard to prevent possible damage during transportation.

Wearing blue light blocking glasses before bedtime can improve sleep, health (through melatonin washout) and morning energy. Read the article on what melatonin is for and how to increase its levels or why sleep is important and how to work on not improving it.

Blocking the green part of the spectrum at the same time as the blue has been found to increase positive effects on sleep quality. ¹

Warning: wearing glasses that block 100% of blue and green light all day can cause fatigue.

The problem of blue light

In today's digital era, few people can take their eyes off the screen, whether it's a TV, cell phone, or computer. With the increasing use of these electronic devices and the use of LED lights, new problems have arisen.

• Exposure to blue light from screens disrupts melatonin production and sleep patterns. You can learn more in our article.
• Blue light from screen exposure has been linked to retinal damage, cataracts and macular degeneration.
• Visible blue light is higher energy and exposure to it is very exhausting for the eyes.
• Over-saturation of blue light can reduce visual acuity and make focusing difficult.
• Blue light has been shown to induce photochemical damage to the retina and macula causing oxidative stress to the eyes.
• Sleep disturbances can lead to depression, accumulation of neurotoxins and increased risk of disease.

Blue light between 380 and 470 nm is considered harmful because it can cause retinal damage, cataracts and is associated with sleep disorders. However, not all spectrums of blue light are bad, for example the spectrum from 470 to 500 nm, calledalso called turquoise blue light, is generally considered good.This range of visible blue light is beneficial because it stimulates natural reflexes to protectthat protect the eyes from overexposure and also helps the cognitive and memory functions of the brain.It also stimulates the photosensitive retinal ganglion cells, also the pupillary reflex and controls the circadian cycle.
