The Intellilens computer glasses for men and women are high-quality blue cut glasses that assist with harmful blue filtering to ease digital eye strain.

 Blue light is a type of visible light that has a relatively short wavelength and high energy. It is emitted by the sun, as well as by many artificial sources such as smartphones, tablets, computer screens, and LED lights. Blue light is known to have both positive and negative effects on our health.

Blue light exposure during the day can be beneficial as it helps regulate our circadian rhythm, or internal body clock. It helps us stay awake, alert, and improves our mood. Natural blue light exposure from sunlight is particularly important for maintaining a healthy sleep-wake cycle.

However, excessive exposure to blue light, especially in the evening and at night, can have negative effects on our health. Research suggests that blue light exposure in the evening can suppress the production of melatonin, a hormone that regulates sleep. This can disrupt our sleep patterns and make it difficult to fall asleep or have restful sleep.

Blue light has also been associated with digital eye strain or computer vision syndrome. Prolonged exposure to screens emitting blue light can cause eye fatigue, dryness, blurred vision, and headaches. Some individuals may be more sensitive to the effects of blue light than others.

To mitigate the potential negative effects of blue light, many people use blue light filters or wear blue light blocking glasses. Blue light filters are software applications or settings that reduce the amount of blue light emitted by electronic devices. These filters usually have a yellow or orange tint, which helps to block the blue light and make the screen appear warmer.

Blue light blocking glasses are specialized eyewear designed to filter out or block blue light. They have lenses that are treated with a special coating that absorbs or reflects blue light. Wearing these glasses while using electronic devices can help reduce eye strain and improve sleep quality, especially when used in the evening or at night.

It's important to note that while blue light filters and glasses can help reduce the potential negative effects of blue light, they are not a complete solution. It is also recommended to practice good screen habits, such as taking regular breaks, maintaining proper posture, and adjusting screen brightness to reduce eye strain.

In summary, blue light can have both positive and negative effects on our health. While moderate exposure during the day is beneficial, excessive exposure in the evening and at night can disrupt sleep patterns and cause eye strain. Blue light filters and blue light blocking glasses are commonly used to mitigate these effects.
