Just like regular glasses: you put them on and that's it. They don't have a prescription, so you don't need one nor an adjustment period — you can use them as soon as you receive them, for as many hours a day as you like.

What sets them apart from other blue light glasses?

Each Stir Vsion lens is designed for a specific time of day; it is not a single lens for everything. With the PRO line, you choose the exact filtering you need, depending on whether you will be wearing them during the day, in the afternoon, or before sleep.

How long does it take for me to notice the effect?

The lens starts filtering some of the blue light the moment you put them on. How much you notice it depends on the individual and how many hours you spend in front of a screen.

How much time do I have if I want to return them?

You have 30 days from when you receive your order to return it if you are not convinced — it is the minimum required by European regulations, so you can shop with peace of mind.

DAILY USE

NIGHT USE

The art of a good unplugging.

The final hours of the day are usually the ones with the most screen time: your phone on the sofa, a series before bed, your laptop until late. The red lens of PRO NIGHT MAX is the most intense filter in the Stir Vsion range, designed for that last stretch of the day — so you can keep up with your usual routine, but with less blue light getting in the way.
