Blue light glasses: protects from computer light
Light is essential for the proper functioning of the eye. The entry of light waves towards the retina is what allows us to see. But what happens when we are exposed to artificial lighting? Harmful health effects are beginning to appear that can be mitigated by simply using blue light glasses.
Shortly, we will study the general effects of this light and how it can be harmful to our eyesight.
General information about blue light lenses
You’ve probably heard about blue light blocking glasses. But, it is not a simple trend but a new need. Overexposure to light from electronic devices has caused proven damage to the eyes from spending too much time in front of screens.
In this sense, blue light glasses have proven to be effective in combating the side effects derived from the indiscriminate use of illuminated screens. Especially for those users who spend hours in front of a computer due to work dependency
These accessories are made with a filter that reduces the arrival of blue light waves to the eye. But, it is important to know that it does not eliminate them completely. So it is recommended to take periodic breaks to increase the effectiveness of the blue filter glasses.
What is the blue light?
Simply put, blue light is a shade found in the visible light spectrum. The sun emits this color of light. Being outside on a sunny day exposes you to blue rays and is the most abundant natural source.
However, the concept of what blue light is has become relevant nowadays due to the blue lighting emitted by electronic devices. Although they only produce an infinitesimal fraction compared to the larger star, the damage they generate is more serious. Since people spend much of the day checking their phones, working on their computers, or reading on their tablets, they require blue light glasses. As a result of this habit, health conditions have appeared and accelerated the development.
How does blue light affect us?
Almost all available blue light passes to the retina because it is difficult for the human eye to block. If we add to this several continuous hours of using screens without blue light glasses, we obtain the following results:
- Alteration of the circadian rhythm that is responsible for regulating the sleep and wake cycle. The LED light from the screens tells the brain that it is still daytime, causing severe sleep disturbances.
- Age-Related Macular Degeneration known by the acronym AMD. It is a disorder that affects a part of the retina called the macula. The blue light destroys the cells in this place until they cannot regenerate
- Eye fatigue caused due to blue light reducing image contrast. It forces the eye to exert extra effort to focus
Advantages of blue light glasses
Blue light glasses can help minimize the negative effects of blue light by providing these benefits:
- Anti blue light glasses improve the contrast of the visual field.
- They mitigate insomnia because they block the passage of this light to the retina.
- They prevent early AMD generated by excess blue light.
- Reduces redness and stinging caused by eye fatigue.
- Reduces the risk of suffering from permanent vision defects.
