Thank you for choosing J+S Computer glasses!

LCD (low color distortion, top)

Designed for general daily usage e.g. less than 4hrs a day, colour sensitive work (e.g. photoshop, graphics design etc). Best if you want a good level of protection while looking good.

HD (heavy duty, bottom)

Perfect for extended usage e.g. less than 8hrs a day, intense gaming sessions, watch a lot movies, or people who do a lot of excel work. It’s great if you want the best protection and you don’t mind the lens being a bit yellow.

As the the blue light blocked by our computer glasses sits on the high energy portion of the visible light spectrum (close to the UV light spectrum), it cannot be easily visualized with the naked eye (hence why online tests don’t work).

Best way to test these glasses is to use a 405nm blue laser pen like the one below:

(You can get a cheap one from Amazon for $7~10 – link: https://amzn.to/2C0sMKR)

When you shine the blue laser at our J+S computer glasses, the blue light waves will be blocked, creating a shadow behind the lens.

This means blue light is being block and the computer glasses is working as intended.

Unfortunately it’s not possible – these online tests are designed for orange colored sleep glasses only. Orange glasses work by removing the entire blue spectrum, turning your entire vision orange. Our blue light shield (and computer glasses in general) are designed to block out the most harmful part of the light spectrum and let through the less harmful rays to reduce color distortion so you can see near normal colors.

These glasses are non-magnified computer glasses, they are best suited for people with healthy eyes.

Our magnified reading glasses are specifically design for middle to old age people with presbyopia (diopter strength range from +1.0 to +3.0). They are great gift ideas for parents, grandparents, aunts and uncles who requires reading glasses for their iPads/tablets, computers, TVs etc.

For most people these glasses will work right out of the box. For a small number of people it may take a while to get used to them especially if you’re not used to wearing glasses before, during this adjusting period you may experience discomfort or headaches.

We recommend trying the glasses for a week or two and see if things improves. Also don’t forget to take breaks every 20 mins or so, and let your eyes rest in a dark area (if possible) to minimize eyestrain!
