Frequently Asked Questions

– Do your filters help with Meares-Irlen Syndrome?
Yes. Our filters have been developed very carefully over a number of years by experts to ensure the range you see will suffice in the vast majority of sufferers. In some cases, a customised solution is needed, in which case you can use our customiser.

-Do your filters help with everyday tasks as well as reading and VDU?

Yes. Our filters are designed for multi purpose use. If you benefit from them with reading, writing and VDU tasks, then they will also help with everyday issues especially flicker from lights or any strobing. 

-How do your filters work?

That is proprietary information but we can tell you our filters block out those wavelengths in the spectrum that cause Meares-Irlen Syndrome from one individual to another. 

-Are you UK based?

Of course! All our filters are manufactured at our lab, here in the UK. Our frames and filters are all CE marked. If you hear anyone saying otherwise, please report them to us. We take our reputation and any slander against our name extremely seriously.

-I’ve read that the overlay colour or the chosen colour on the screen won’t be the same as my filter because of transmitted light vs reflected light. Is this true?

No. The empirical data suggests this isn’t necessarily the case for the overwhelming majority. 

– Do your glasses have UV protection as standard?

Our lenses are CE rated and provide satisfactory UV protection and block the majority of harmful UV radiation. However, to ensure full UVA and UVB protection so you can protect your eyes outside, they need to be specially treated with a UV coating. This is the only way to achieve complete UV protection via optical labs. 

– Will wearing coloured filters similar to my overlay harm my eyes?
There is ZERO evidence to suggest coloured filters cause ocular damage much less those that are similar to an overlay. We’ve yet to see any scientific basis behind such claims. Please ask for evidence of this.

– I’ve been told by a supplier I will see normal colour vision through their tinted lenses.

If a lens is tinted any colour, it will affect colour vision. 

Ask to try their sample lenses first to verify this claim.

The ONLY way to correct Meares-Irlen Syndrome and have normal colour vision is through Clear Honeycomb Lenses which you can buy at Read123.

Will my filter colour be the same as the screen?

Our standard filters are based on an iphone screen. If you are using any other device, there will be a slight variation in the colour due to screen calibrations. If you’re using a device other than an iphone, please use the customiser on our website. Alternatively, you can send us your current filter and we’ll replicate it in our lab. 

Do you mix colours to achieve your filter colours?

– Of course we do. We mix 3-4 different colours to get our filters just right. Yet even with a task like this which requires the utmost concentration and skill, Read123 are extremely affordable.

Can I use my Irlen/Cerium codes with you?

-You can use our customiser to see which colour works best for you. If you find a colour mix that i right for you, then that will work in your filter. 

– Do you use proper frames and lenses?
All our frames and lenses are CE marked and made to only the highest standard. We don’t use “fake” or “cheap materials from China” as some trouble makers might claim!

– Can you make prescription lenses for children under 16? 

No. If your child’s glasses have been made by a suitably qualified professional, then you can send them to us to have the filter applied. 

– How long will my glasses take to deliver?
UK standard delivery is 14 days as our lenses have to be sent to the laboratory to made up. A Priority Service option of 5 days for the UK is available at checkout. International delivery is 21 days with a Priority Service of 14 days.

– How does the exam discount code work?

You simply pay for the diagnostic examination which is a complete comprehensive examination designed by our experts. If you are diagnosed as needing glasses, then we will redeem whatever you’ve paid towards the cost of the glasses, so saving you money.
