When we see close objects.
When we see close objects.
- Ciliary muscles relax , zonules contract lead to the lens becoming thinner so refractive power decreases.
- Ciliary muscle contract, zonules relax lead to the lens becoming fatter so the retractive increases. (correct)
- Ciliary muscles relax, zonules relax lead to the lens becoming thnner so the refractive power decreases.
- Ciliary muscles contract, zonules contract lead to the lens becoming fatter so the refractive power increases.

Study Notes
Visual Processing
- Contralateral control occurs when external stimulation or learning leads to a response when seeing close objects.

- The function of V9 is not specified in the provided text.
Photosensitive Epilepsy
- Filters are used to help individuals with epilepsy and migraines.
- Severe, prolonged headaches can lead to migraines.
Photosensitive Epilepsy Triggers
- Not all triggers of photosensitive epilepsy are specified in the provided text, but some triggers are not mentioned.
Dyslexia and Motion Perception
- Dyslexic individuals are less able to identify coherent motion amongst random motion.
- Dyslexic individuals need 20% more dots in random motion to see coherent motion.
