Scotopic sensitivity, also known as Irlen syndrome, is said to cause visual distortion of print material when attempting to read unaided from white paper.

It is usually identified in students by an Irlen diagnostician using a series of vision tests.

Coloured lenses or overlays – designed for the specific needs of each individual student – are then prescribed for use at school or in exams.

These coloured lenses and controlled lighting meet the needs of most students.

A small percentage of students with scotopic sensitivity may also need coloured paper.

If a reading test with coloured lenses, controlled lighting and white paper shows a student’s reading rate, accuracy or comprehension is significantly below their cohort, coloured paper will be provided for their exams.

Some students also require coloured paper because they become extremely anxious or fatigued and are unable make a fair attempt in their exams when reading black print on white paper.

Coloured paper is also provided for these students.

For the 2014 HSC BOSTES has approved coloured lenses and appropriate lighting disability provisions for 117 students. Coloured paper will also be provided for 19 of these students.
