Gabor patterns: carefully controlled detail
Fine stripes inside a simple pattern. Adjusting their contrast, size and orientation gives the weaker eye practice with detail it finds hard to distinguish.
Visual training for amblyopia (lazy eye)
Your eyes have more to see.
NAYIR is a visual training program for adults and children with amblyopia. It uses Gabor patches and perceptual learning to practise distinguishing detail and contrast, under your clinician’s supervision. Individual assessment and follow-up determine whether it suits your situation.

GABOR PATCHES & PERCEPTUAL LEARNING
Train your brain to see more clearly.
Amblyopia also affects how the brain processes an image. NAYIR uses Gabor patterns and perceptual learning to work on fine detail and contrast through regular practice.
What has perceptual-learning research studied?
Specific studies have investigated whether perceptual training can improve some vision measurements. Their results apply to the participants and protocols studied; they do not establish NAYIR’s effectiveness or predict your outcome.

A NEW STEP FOR YOU OR YOUR CHILD
Been told
it’s too late?
Research on Gabor-pattern training has shown improvements in visual acuity and contrast sensitivity in adults with amblyopia. Reaching adulthood does not have to mean the end of opportunities to improve your vision.
Find out how to start with NAYIROver 12?
Visual learning extends beyond childhood. Perceptual-learning studies have reported acuity and contrast improvements in teenagers and adults.
Patching hasn’t delivered enough improvement?
NAYIR turns use of the weaker eye into active practice, using Gabor patterns and perceptual learning in a program followed by your clinician.
Looking for further improvement?
The program works on fine detail and low-contrast patterns, giving you a way to pursue progress beyond simply logging patching hours.
Patching alone × with NAYIR: what changes?
Patching alone
Passive use of the weaker eye: the patch covers the stronger eye, but by itself does not provide targeted practice with fine detail and contrast.
Patching can bother a child and make studying and everyday activities harder.
Some children resist the patch or feel self-conscious around others. Skin irritation and difficulty sticking to the routine can also occur.
With NAYIR
RecommendedActive Gabor-pattern and perceptual-learning training aims to improve visual acuity, contrast sensitivity and fine-detail discrimination.
A structured home program with progressive exercises and breaks. The patch required for training is worn during the session.
Your clinician can review session records and follow-up measurements to track progress and tailor the plan to your situation.

The patch needed for NAYIR is worn during the home session, keeping the training routine separate from playtime. Your child’s clinician decides whether their plan also needs additional patching.

See the difference
in the details.
Amblyopia can make small or faint details harder to distinguish. NAYIR aims to train visual skills and track changes through measurements with your clinician.
VISUAL ACUITY
Visual acuity
With amblyopia, small letters may look incomplete or crowded, and some details can be hard to distinguish. NAYIR trains you to distinguish fine detail to improve visual acuity.

Contrast sensitivity
Your ability to notice subtle detail, such as wood grain. Reduce the contrast to make the detail fainter while preserving the wood’s colour and saturation.

BUILT ON A RESEARCH IDEA
The science behind
visual training.
The brain can learn to distinguish visual detail it previously found difficult. Research on perceptual learning and Gabor patterns supports this principle and informs the NAYIR program.
SYSTEMATIC REVIEW · 2025
Progress is possible beyond childhood
Adults showed better visual acuity after training, supporting opportunities to improve vision beyond childhood. A review covering 22 studies and 422 adults reported this result.

Finer detail and better contrast
Gabor-pattern training improved visual acuity and contrast sensitivity: the ability to distinguish smaller detail and fainter patterns. The 2004 study included participants aged 9 to 55.

A route after patching stalls
Children who had not achieved the desired result with patching improved in visual acuity and contrast sensitivity after perceptual-learning training. This small pilot of five children offers a reason to discuss additional options with your child’s clinician.

Research details for cliniciansIs NAYIR for both adults and children?
The program is intended for adults and children with amblyopia. Suitability starts with diagnosis, vision measurements and the ability to understand tasks and respond independently.
Will I use an eye patch during training?
Yes. Training uses a patch over the other eye and your prescribed glasses, according to your instructions. NAYIR adds progressive visual tasks and performance tracking throughout the program.
Can I train on my phone?
Training requires a laptop or desktop and a physical keyboard with arrow keys. You will also need a ruler to set the on-screen size and a tape to measure viewing distance.
How much training time do I need each week?
The initial plan is four weekly sessions for around three months. Each session includes 60 minutes of active practice, or about 72 minutes including breaks, with monthly clinician follow-up.
