Our glasses use two technologies in order to block the blue light, and the UV as well :)

1. The material itself of the lenses absorbs the blue light

2. The external surfaces have a coating that reflects the blue light, allowing our lenses to be more clear as if they were just blocking light through the raw material of the lenses

Our high quality organic CR-39 lenses block 100% of the Blue Light under 410nm and 45% of the Blue Light on the 410nm - 450nm spectrum. Keeping your eyes more relaxed and comfortable while using digital devices in any kind of situation. Think of them as protective eyewear for digital professionals!

Yes! And please, use them. You won't only keep your eyes more relaxed, but you'll also fall asleep faster and have a deeper sleep. There are studies showing that blocking blue light from digital devices at night can help you increase 2 to 3 times more your melatonin levels.

Hello!

We offer Single Vision lenses Sphere (SPH) correction for nearsightedness or farsightedness glasses, in power range from +6.00 to -8.00, and Cylinder (CYL) from +4.00 to -4.00.

The easy steps are the following:

1. Make sure you have an updated ophthalmological prescription.

2. Once you place your order with the prescription, you will receive your "Thank You" confirmation email with the prescription form.

3. Make sure you write down the exact prescription that your doctor gave you, as this will be what our lab will assemble :)

> Information we will ask you in our prescription form:

1. Your myopia for both eyes. In your prescription should be named as sphere, SPH or ESF. If you just need simple reading glasses (+1, +1,5, +2, etc.), you would only have to fulfill this parameter.

2. Your astigmatism for both eyes. Astigmatism is detailed by two concepts, Cylinder and Axis. Cylinder can be named as CYL.

3. Your pupillary distance. To properly center your prescription in your chosen frame we need the distance between your pupils or the distance between your pupils to your nose. If you don't have it you can measure it by yourself, here you have a picture of what is the Pupillary Distance: https://www.eyeweargenius.com/wp-content/uploads/2018/11/Dual_Pupillary_Distance.jpg

With all this information you will have very soon your new prescription glasses!

The glasses shouldn't have any strength or magnification. Also, they are done with high quality organic CR-39 materials which avoid this kind of magnification.

Nevertheless, if you want to make sure there is no magnification on your lenses, please go to your closest optician and ask them to check if there is any prescription on the lenses. If that is the case, please let us know and we will exchange your glasses immediately.

This kind of magnification feeling that could happen to few people when starting to wear computer glasses could be done because when removing some part of the Blue color you get a different color contrast which you are not used to and it could cause this strange feeling.

If this is your case, it should happen only at the beginning, after a while, it should be all good ;)

Yes, all of our models are unisex and work perfectly with a whole variety of face shapes.

Of course! We are a screen glasses company, therefore our lenses' choice for the clip-on is non-polarised solar lenses. It will allow you to see your digital devices in perfect conditions.
