Crystal Blue Light Blocking Glasses

Our Blue Light Blocking Glasses are based on science and created in line with peer reviewed academic literature. Our Blue Light Blocking Glasses are not simply a fashion accessory.

The exact frequencies of light in line with science are blocked with our amber/red lenses. We know that blue and green light found between 400nm-550nm disrupts melatonin production and damages your sleep. Our Blue Light Blocking Glasses block 100% of blue and green light that falls between 400nm and 550nm ensuring you have the most optimal blue blockers in the world.

Our glasses are made in an optics laboratory meaning experienced optical technicians create each lens. This also allows us to offer a prescription and readers service as well as non-prescription.

We offer full transparency on our lens capabilities, making our lens report guides available to everyone on our website before purchase, allowing you to see exactly what frequencies of light are blocked. These can be found under each individual product on the website.

Our Blue Light Blocking Glasses are classified as medical devices in the USA and Australia and are registered with the FDA and ARTG.

Our Blue Light Blocking Glasses are made under world class optics laboratory conditions, not mass produced in a factory. This gives them unrivalled optical grade quality

Our Blue Light Blocking Glasses technology is custom made, targeting the exact frequencies of light the academic literature states we should filter (100% blocking from 400nm to 550nm). Not all blue light glasses on the market target specific wavelengths of light and either block too little or too much of the wrong kind of light, making them suboptimal.

Our Blue Light Blocking Glasses frames use the highest-grade materials available which gives them the perfect fit and comfort when wearing them. Often, cheaper pairs use low quality acetate which will feel heavier and uncomfortable when you wear them.

Our Blue Light Blocking Glasses work by filtering out 100% of harmful blue and green light that may be disrupting your sleep. By blocking 100% of light between 400-550nm our Blue Light Glasses can boost melatonin production and improve sleep quality and quantity.

Pop on your Blue Light Blocking Glasses 2-3 hours before your bedtime to notice the incredible difference in your sleep after just one use.

We are delighted to offer both prescription and reading glasses options as well as non-prescription options.

Simply select whether you’d like non-prescription, prescription or readers once you click on them. For prescription service, upload your script on the product page, and we will then custom make your desired lenses in your very own prescription.

Prescription glasses can be single or multifocal options and are made in our optics lab.

For readers, you easily select your magnification between +0.25 to +4.00 on the product page once you have chosen your frames. We offer readers in +0.25 increments.

If you cannot find a frame you like you can use our custom frame service where you can send us your own frame to add our lens technology to.

Firstly we recommend identifying which frames will best suit your face shape, see our size guide on the top. Secondly, check the frame measurements by using our size guide.

Our favourite picks: - For a small face size choose Denver or Echo - For a medium face size choose Parker or Tortoise Shell - For a large face size choose Smith or Maverick.

If your BON CHARGE glasses arrive and do not fit, your local optometrist can easily adjust them to fit you perfectly. They do this either for free or for a nominal fee. However, you can exchange as many times as you like with BON CHARGE until you get the perfect frame for you.

Our Blue Light Blocking Glasses should be worn 2-3 hours before bedtime. Once you pop your Blue Light Blocking Glasses on do not remove them until you are in bed and ready to sleep.

We do not deem peripheral light too much of an issue.

The iPRGC receptors are in the inner retina and function in such a way that the extremely minor light that may peek through sides or top of frames is not enough for the PLR (pupillary light reflex) to phototransduct to any large degree because the iris is open to a wider diameter due to the lens themselves already putting a dynamic reduction in light volume.

However, if you suffer from light sensitivity and deem peripheral light an issue, we recommend our fully wrap around frame called Onyx.
