Blue Light and the Pros and Cons of Glasses
What is blue light?
Blue light falls between ultraviolet light and visible light on the light spectrum. It is emitted from the sun, as well as from electronic devices such as phones, tablets, and TVs. Too much exposure to blue light at night can suppress melatonin, making it harder to sleep.
What are the pros and cons of blue light glasses?
Blue light glasses have lenses that are designed to block or filter out blue light. There are some potential benefits to wearing blue light glasses, including:
- Reduced eye strain
- Improved sleep
- Protection from age-related macular degeneration (AMD)
However, there are also some potential cons to wearing blue light glasses, including:
- They may not be effective at blocking all blue light
- They can be expensive
- They may not be necessary for everyone
Do blue light glasses actually work?
There is some evidence to suggest that blue light glasses may be effective at reducing eye strain and improving sleep. However, more research is needed to confirm these findings. One study found that wearing blue light glasses for two hours before bed improved sleep quality in people who had difficulty sleeping. Another study found that blue light glasses reduced eye strain in people who worked on computers for long periods of time.
It is important to note that blue light glasses are not a cure-all for eye strain and sleep problems. If you are experiencing these problems, it is important to see an eye doctor to rule out any underlying medical conditions.
Who should wear blue light glasses?
Blue light glasses may be beneficial for people who experience eye strain or difficulty sleeping. They may also be beneficial for people who are at risk for AMD. However, it is important to talk to an eye doctor to determine if blue light glasses are right for you.
How to choose blue light glasses
If you are considering purchasing blue light glasses, there are a few things you should keep in mind:
- The type of lenses. There are two main types of blue light glasses lenses: those that block all blue light and those that filter out only some blue light. The type of lens you choose will depend on your individual needs.
- The fit. It is important to make sure that your blue light glasses fit well. Glasses that are too tight or too loose can be uncomfortable and may not be effective at blocking blue light.
- The price. Blue light glasses can range in price from $10 to $100. The price will depend on the type of lenses, the fit, and the brand.
Conclusion
Blue light glasses are a popular way to reduce eye strain and improve sleep. However, it is important to talk to an eye doctor to determine if blue light glasses are right for you. If you are considering purchasing blue light glasses, be sure to keep the above factors in mind.
