How can more light be gotten into the eye if iris or pupil won't open up?

If the iris or pupil won't open up to allow more light into the eye, one option is to use artificial lighting, such as bright lamps or flashes, to enhance visibility. Additionally, using a magnifying glass or other optical devices can help focus available light onto the retina. In some cases, medical interventions may be necessary to address underlying issues affecting the iris or pupil. However, it's crucial to consult an eye care professional for proper diagnosis and treatment.
