Why do doctors dilate eyes?

is there any side-effect of dilating the eye?

Answers:
Doctors dilate your eyes to be capable of see the back of the eye (the retina). It's defining that the retina is healthy and functioning properly. If you hold glaucoma or high intraocular pressure, your doctor may not want to dilate you (it may induce angle closure glaucoma surrounded by at-risk patients). It's also not a good hypothesis if you have amazingly high blood pressure. As far as adjectives side effects, your vision will be blurry for 3-4 hours after the drops and you may be extra muted sensitive for that time.
only if they want to look into your eye. They will use a bright desk light to shine in your eye, in general your pupil contracts in response to bright restrained. So nobody can look in - unless you pass eyedrops which dilate the pupil regardless of ambient light level.
A doctor may want to look into your eye in lay down to look if your retina looks healty or if there are change in blood vessel and so on.
The "side" effect is, that it takes some time for the medication to wear stale. You may find pretty normal muted levels too bright. Bring sunglasses to wear afterwards and you should be fine.
The atropine solution used to do this used to be used by photographers too. A 'trick' to receive the models eyes appear more attractive. The bright lights in a studio would otherwise formulate the pupils small - normally this is also associated beside anger and aggression & not very attractive!
dilatation of the pupils jelps the doctor to own a good scenery of your Retina in individual.this is done to rule out any pathology.
eyes are not dilated its the pupil that is dilated

pupils are dilated to perfom fundoscopy i.e to obsereve the retina or to detect any opacities contained by the eye

or to perform retinoscopy i.e to evaluation of refractive errors (in instruct to avoid accomodative effort)
