The dilating drops dilate the pupils of the eye. The pupils are like the window to the eye and once they are dilated we can examine the inner part of the eye which is the vitreous cavity, retina and optic nerve. Once the pupils are dilated patients would experience blurry vision for the next 2-3 hours till the pupils return to normal size.
In children we instill different dilating drops. Children need eye drops to also confirm the eye number or the spectacle power. Though the effect of the dorps is the same, the blurriness lasts for 24 hours. This is expected so there is nothing to be alarmed about.
