Blue Light Protection

Without getting too much into the intricate physics behind how light travels through your eye we can briefly explain there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Blue-light is on the shorter side of the light spectrum meaning this type of light contains more energy.

Sunlight is the number one source of blue light.

However, there are many indoor sources of blue light such as fluorescent and LED lighting. The most common being the display screens on our computers, smartphones, televisions and tablets. These digital devices emit significant amounts of concentrated blue light directly into our eyes with each use.

The human eye is very effective at blocking UV rays from reaching the light-sensitive retina at the back of the eyeball. However, when it comes to blue light virtually all light passes through the cornea and lens and reaches the retina. It is thought that too much exposure to blue light can affect light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to vision loss.

Everyday side effects of blue light are that it can interfere with your sleep quality, cause screen-induced migraines and lead to eye strain.

You have probably noticed more technology such as smart phones and laptops offering you 'night-mode' options?
Blue light lenses work in a similar way...

More than any other colour, blue light confuses your body by blocking a hormone called 'melatonin' which can make you feel tired. So, if we spend a lot of time staring at screens our bodies may artificially feel awake and subsequently we take longer to fall asleep.

As blue light glasses are relatively new to the market there is not a lot of research to prove their immediate benefits however it has been widely recognised that blue light blocking lenses minimize eyestrain, improve your sleeping habits through increased visual comfort.

No. You don't require a prescription lenses to order blue light glasses.

Computer glasses are a great way to combat the blue light exposure from computers and other digital devices. You can purchase these as special-purpose glasses without a prescription. This can be beneficial if you have no need for vision correction or if you routinely wear contact lenses.
