Blue Light Blocking Glasses

Blue light blocking glasses are eyeglasses lenses that are designed to block out blue light. Blue light is a type of light that is emitted by electronic devices such as smartphones, tablets, and computer screens. Blue light reading glasses and non-prescription blue light glasses are also available at EFE.

Blue light blocking glasses are designed to filter out blue light and allow you to see clearly without the negative effects of blue light exposure.
Many people believe that blue light blocking glasses work by blocking the blue light that is emitted by electronic devices. However, it's important to note that blue light is a type of light that is not easily blocked by glasses or other optical surfaces. Blue light can be blocked by certain types of glasses, such as blue light-blocking glasses, but it can also be reflected and refracted by other surfaces, such as water and snow. This means that while blue light blocking glasses may help reduce the amount of blue light that reaches your eyes, they may not completely eliminate the negative effects of blue light exposure.

There are several potential benefits to using blue light blocking glasses:
1.Reduces eye strain;
2.Protects your eyes from damage;
3.Promotes better sleep;
4.Protects your eyes from other harmful light.

Exposure to blue light has been shown to disrupt the production of certain hormones in the brain, which may lead to symptoms such as headaches. Some studies have found that using blue light glasses can help reduce the frequency and severity of headaches.

Some studies have suggested that blue light glasses may be effective in reducing fatigue and improving alertness, but the evidence for this is not always consistent and more research is needed to fully understand the potential benefits and limitations of blue light glasses for reducing fatigue.

There are several ways to tell if your glasses are blue light:
1.Brand: Some glasses are specifically designed to block blue light, so if you have a pair of glasses that was specifically prescribed for blue light reduction, it is likely that they are blue light glasses.
2.Appearance: Blue light glasses may have a slightly tinted or brownish color to them, and may also have a noticeable blue or purple tint to the lenses.
3.Lenses: Blue light glasses may have a special filter that blocks out blue light, or they may be made of a special type of glass that blocks blue light.
4.Certification: Some glasses may be certified as blue light blocking by organizations such as the Blue Light Filter Project or the American National Standards Institute (ANSI).
5.Packaging: Blue light glasses may be packaged differently than non-blue light glasses, with different instructions for use and warnings.
