Objectives: Advances in dental operative microscopes (DOMs) enable examination of root canal morphology or detection of root fractures otherwise not visible to the naked eye. However, dental therapy involving prolonged use of DOMs requires precision within a limited visual field, resulting in eye strain among users. This study examined the effects of halogen and light-emitting diode (LED) light sources on asthenopia and visual function following use of DOMs.

- - The study aimed to train 45 school children with myopia using a visual stimulation device that created a blur stimulus while maintaining constant image size and brightness, to assess its effects on various vision metrics.
- - Over a year, 42 out of 45 children successfully completed the training, with notable improvements: the mean refraction decreased and axial length increased, indicating enhanced visual acuity.
- - Key dynamic accommodation measures improved significantly, including a reduced latency in response time, higher gain in the accommodative phase, and increased maximum speed of accommodation throughout the training period.
