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 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 coloured lenses.

If a lens is coloured, it will affect colour vision. 

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

– Will my filter colour be the same as the screen?

The colours you see on the website are how text will appear when viewed through the filters.

– What if the filter doesn’t work, can I return the glasses?

We’ve never had anyone return our glasses because the filter didn’t work using our method. Please see the reviews on our website and Trustpilot. If your chosen filter colour either from your overlay, or any of our tests on the website is correctly determined, then our Read123 Clariti Lenses™ will work. If you want to be absolutely sure, then please request a testing kit by email or phone call. Or you can send us your colorimetry results.

– 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. These are then passed through a Spectrophotometer to ensure the transmission of wavelengths is acceptable. 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 send us your results. We can certainly take a look and guide you to the colour filter that will help you. 

– Can I use my Disability Student Allowance with you?

Yes of course you can. Email or call us to discuss this. 

– Do you use proper frames and lenses?
All our frames and lenses are CE quality and made to only the highest standards. 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 working 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 working 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 at checkout, so saving you money.
