About blue light glasses
Why should I buy blue light filter glasses?
Blue light filter glasses are designed to filter blue-violet light*, which is a type of high-energy visible (HEV) light emitted by the sun and is potentially harmful.
There are 3 types of blue light, including:
- Blue-violet light.
- Blue-turquoise light.
- LED blue light.
Blue turquoise light and LED blue light are emitted by electronic devices such as smartphones, tablets, and computers, as well as fluorescent and LED lighting. However, the main source of blue light is the sun, even when you’re indoors. Learn more.
Do I need a prescription for blue-violet light glasses?
No, blue-violet light filter glasses do not typically require a prescription. You can buy these glasses online or at your nearest Vision Express store. These blue-violet light glasses are non-prescription (non-magnification). However, you can add our Easy clean plus blue lenses with or without prescription to any pair of glasses to suit your style.
If you have specific vision needs or eye health concerns, it's a good idea to book an appointment with your local Vision Express optician for an eye test. They can help you determine the best type of eyewear for your needs and make sure that your eyes are healthy.
*Blue-violet light is between 400 and 455nm as stated by ISO TR20772-2018.
