Alegria UV Prescription Transmitter Lenses (Base Frame Only)

Daytime Circadian Light Harmonizing Glasses is a cutting-edge technology designed to protect your eyes from the harmful effects of blue light emitted from digital screens and artificial lighting. 

These glasses are scientifically engineered to harmonize the harmful narrow peak at 455nm of blue-violet light, which can cause eye strain and headaches, and replace it with a more natural distribution of colors.

They are perfect for people who work indoors under artificial light bulbs and/or who spend long hours in front of screens, as they effectively reduce eye fatigue and allow you to work for longer periods without experiencing discomfort.

Unlike regular blue light-blocking glasses,  Daytime Circadian Light Harmonizing Glasses, you can enjoy the benefits of natural light coming through the window while eliminating the negative effects of junk blue light coming from artificial lights and screens. 

The technology behind these glasses is backed by science, so you can be confident that you are making a smart investment in your health.

Here are a few of the countless benefits you instantly access when you expose your eyes to UV light from sunlight:

 • Vitamin production

 • Lowers blood pressure

 • Make your heart stronger by 35% 

 • Increases blood flow

 • Decreases the resting heart rate, calming your nervous system

 • Helps you lose weight • Increases sex hormones (on average 120% after exposure to UVA and UVB) 

• UV helps to control apoptosis which is important to prevent cancer • Increases your mood and improves your sleep

 • Increases your energy, endurance, and muscle strength 

Did you know that the more sun exposure you have (which includes UV light), the lower your chances of dying from all-cause mortality? And that even includes skin cancer!

 • Wear your UV Transmitter lenses the same way you wear your regular prescription lenses.

 • As soon as you go inside and you are exposed to artificial light, snap your VivaRays Daytime Lenses.

  • After Sunset, snap your VivaRays Evening Lenses • 2 hours before bed, switch to your VivaRays Night lenses.

We know that too much light into the eyes can be damaging. This is why your pupils have the ability to constrict (they get smaller, decreasing the amount of light reaching your retina) or to dilate (they get bigger, increasing the amount of light reaching your retina). Even if we don’t have the capacity to see UV light, there are special receptors in our eyes that can detect it. These receptors send feedback to our brain to help control the constriction/dilatation of the pupils. So when you are outside wearing prescription glasses or sunglasses that block UV light, your pupils lose their ability to constrict properly. After a while, your eyes become much more sensitive to sunlight because you don’t have the ability to properly constrict your pupils. 

After a couple of days where you gradually increase your exposure to natural sunlight with our UV transmitter lenses, your pupils will regain their ability to constrict in response to sunlight and your eyes will be able to tolerate natural sunlight as they should.
