What are blue cut lenses?

Blue cut lenses are lenses that are designed to filter out blue light, a type of high-energy visible light emitted by electronic devices such as smartphones, laptops, and televisions. They aim to reduce the exposure to blue light and mitigate its negative effects on sleep, eye strain and other related issues.

Myths about blue cut lenses

1. Blue light blocking lenses don’t actually block blue light: False, blue light blocking lenses are designed specifically to filter out blue light, which can cause digital eye strain and disrupted sleep patterns.
2. Blue light blocking lenses change the color of everything you see: False, these lenses are designed to filter out specific wavelengths of blue light, not to change the color of everything you see.
3. Blue light blocking lenses protect you from all harm from screens: False, while these lenses can help reduce the effects of blue light, they do not provide complete protection from the harmful effects of prolonged screen use.
4. Only people who work with computers need blue light blocking lenses: False, while they can be helpful for computer users, anyone who uses digital devices for extended periods can benefit from blue light blocking lenses.
5. Blue light blocking lenses are only for people with prescribed glasses: False, you can get blue light blocking lenses in prescription or non-prescription form, so anyone can benefit from them.

Ideal way to use blue cut lenses

1. Use them when using digital devices: The ideal time to use blue light blocking lenses is when using digital devices such as computers, smartphones, or tablets for extended periods of time.
2. Wear them before bedtime: Blue light from screens can disrupt sleep patterns, so it is recommended to wear blue light blocking lenses in the hours leading up to bedtime to minimize these effects.
3. Incorporate them into your daily routine: Make blue light blocking lenses a part of your daily routine to get the most benefit from them.
4. Choose the right lenses for your needs: Choose blue light blocking lenses that fit your specific needs, such as indoor lenses, outdoor lenses, or lenses with different levels of blue light filtration.
5. Consult an eye specialist: If you are unsure about which blue light blocking lenses are right for you, it is always best to consult with an eye specialist or optometrist.

Do blue cut lenses affect normal circadian rhythm

No, blue cut lenses do not affect normal circadian rhythm. Blue light blocking lenses are designed to filter out specific wavelengths of blue light, which can interfere with the production of melatonin and disrupt sleep patterns. By reducing exposure to blue light, these lenses can help maintain a normal circadian rhythm and promote better sleep. However, it is still important to have a consistent sleep schedule and to limit screen time before bedtime to maintain a healthy circadian rhythm.
