Bright like you: a new way to share how you see colour.
The starting point
Around 8% of men perceive red and green tones differently (protan or deutan colour blindness). In most cases the diagnosis arrives in childhood — and with it, many questions at home: how does my child really see? Can I understand him better?
Red-green colour blindness has a hereditary component linked to the X chromosome: the mother is often a carrier without knowing it, because standard tests such as Ishihara plates do not reveal it in women with normal colour vision.
The product
Our patent-pending kit brings together three pairs of glasses with chromatically identical red-filter lenses, in three frames designed for three family members: the diagnosed child, the mother and a third family member acting as a reference.
Looking at the same colour plates through the filters, mother and child can come to perceive the same pattern — what we call the empathy pattern — while the reference person perceives a different one.
It lets the family come closer to how the child perceives colour, turning the diagnosis into a shared experience rather than a label.
The experience can offer an indicative signal of whether the mother is a carrier of the trait — something standard tests do not show.
Red-filter lenses with identical chromatic specification across the three glasses, with a distinct frame for each member.
Important: Bright like you is not a medical diagnostic product and does not replace assessment by an ophthalmologist or optometrist. It is a family integration tool and a colour perception experience.
Where to find it
The kit is offered through a network of partner opticians, with a guided 15–20 minute session, a clear protocol and the corresponding informed consent.
Do you run an optician's practice and want to collaborate? Write to us and we will send you the session guide and terms.

According to the National Eye Institute (NIH, USA), about 1 in 12 men has a colour vision deficiency. The red-green form is by far the most common: it affects roughly 1 in 12 men and 1 in 200 women of Northern European ancestry, with somewhat lower figures in the other populations studied (MedlinePlus Genetics).
Blue-yellow deficiencies are much rarer (fewer than 1 in 10,000 people) and affect men and women equally. Most cases are inherited and present from birth; acquired forms also exist, linked to eye disease, diabetes, multiple sclerosis, certain medicines or ageing (NEI, NHS).
Diagnosis relies on simple tests such as Ishihara plates or colour arrangement tests. There is no cure for the inherited forms, but most people adapt well, and optical and digital aids can make it easier to tell colours apart in everyday life.

Colour blindness does not limit the vast majority of jobs, but Spanish regulations require normal colour vision (or exclude colour vision deficiencies) for entry into certain forces and trades. The requirements depend on the type and degree of the deficiency and are usually checked with Ishihara plates:
Colour vision deficiencies detected with Ishihara plates or other means are not admitted (Royal Decree 326/2021, annex, vision section, item 16).
Normal colour vision is required for entry into the Cabos y Guardias scale (Order PCI/155/2019, medical exclusion table, item 16).
Normal colour vision for Navy General Corps officers and Air Force pilots; in the other corps, troops and seamen, severe colour vision deficiencies are not admitted (Order PCI/6/2019, item 17).
Staff with traffic-safety duties (train drivers, among others) must have normal colour vision on the Ishihara test (Order FOM/2872/2010).
People on lookout duties are unfit with any degree of protan deficiency or severe deutan deficiency; mild deutan may be fit with restrictions (Royal Decree 505/2024, item 3.7.3).
For a class 1 medical certificate (professional pilot) you must be a normal trichromat or "colour safe" after further testing; otherwise you are assessed as unfit. Class 2 (private pilot) is limited to daytime flying (Regulation (EU) 1178/2011, MED.B.075).
By contrast, the driving licence — including group 2 professional licences — requires no colour vision test in Spain: Annex IV of the General Drivers Regulation (Royal Decree 818/2009) does not include one.
Non-exhaustive list; regional and local police forces, firefighters and other professions may set their own requirements in each call. Always check the regulation in force.
In Spain, the official scale for recognising the degree of disability (Royal Decree 888/2022) does not cover colour vision deficiency: visual assessment is based on acuity and visual field. On its own, colour blindness gives no access to the disability certificate or the support attached to it, despite the real limitations it can impose in education, employment and daily life. In the United Kingdom an employment tribunal reached the same conclusion under the Equality Act 2010 (Bessell v Chief Constable of Dorset Police, 2017), and associations such as Colour Blind Awareness are campaigning for change.
If a diagnosis has just arrived at home, these associations offer information, shared experiences and support. They are independent of Bright Like U.
