Which of the following can be a result of using mydriatic substances?

Using mydriatic substances is primarily intended to dilate the pupils for various medical examinations and procedures. One of the key effects of pupil dilation is increased sensitivity to light. When the pupils are dilated, a larger amount of light enters the eye, which can lead to discomfort and glare sensitivity. This can make it challenging for individuals to see well in brightly lit environments or under direct sunlight since more light overwhelms the photoreceptors in the retina.

While decreased pupil size would not occur with mydriatics, as the term "mydriatic" pertains specifically to drugs that cause dilation, reduced vision may occur in specific contexts, primarily if the lighting conditions are not conducive post-administration. However, the evidence strongly supports that light sensitivity is a direct and common consequence of pupil dilation. Therefore, the assertion that increased sensitivity to light is a result of using mydriatic substances is accurate.
