I have Irlen syndrome. Also known as scotopic sensitivity syndrome.
Diagnosed by a specialist Irlen centre. GPs and opticians tend not to use the extensive testing, as it is time consuming, and expensive, using the patented Irlen test materials. Some opticians will provide coloured lenses but not with the intensive assessment that Irlen specialists use.
Irlen syndrome is a perception difficulty, rather than a physical difficulty. It does affect how we see things, though. I have trouble reading text, particularly black on a white background. It was very troublesome prior to my retirement when I did a lot of reading for my work. It is also difficult reading when there is a lot of colour on screen. I am grateful to the forum techies who provide a mild colour versionof the forum. It enables me to see and read without discomfort. I used to get a lot of headaches reading. With coloured acetate overlays and authentic Irlen lenses in my spectacles the problem is eliminated.
@Helen miller , as
@catinahat mentioned, your blood glucose levels could affect your vision. You say they are stable, but haven’t mentioned figures. Also, it is not clear if you have seen an Irelen specialist, or an optician who has not used the approved Irlen resources. The optician who prescribed your lenses has a duty of care to ensure they are doing what they are supposed to.

With the cost of living crises affecting many across the country recent reports have been arriving at the OCCS in regards to refunds for spectacles. In today's blog, we outline your consumer rights into whether or not refunds can be issued for glasses.
