Optometrists dilate a person's eyes so they can see the inside and back of the eyes. An eye exam should be performed annually. An ophthalmologist examines a patient. Normally, a person's pupils contract when light is bright. Routine eye exams are painless and can help detect vision or eye problems early.
Our eyes naturally dilate to allow more light in, but dilation also occurs in response to cognitive and emotional events. So when weâre interested or in any way emotionally stimulated â positively or negatively â in what weâre looking at, our pupils dilate. In fact, men tend to be attracted to women with larger pupils.
