I am wondering if those drops have anything to do with determining the prescription or is the reason for the drops so the doctor can look inside the eye(or both or none of the above)

It is to dilate your pupils.

I wouldn't think so. Do you means drop for dry eyes etc...then why would they change the vision. I guess I misunderstood you, thought you meant drops you use at home.

It's to dilate your pupils so the doctor can more easily view the back of your eyes (the retina).

Or, in the case of some pressure testing, it's to numb the surface of the eye.

Dry eyes alters the focal length of your eye, the tear film provides slight focusing strength, but the cornea distorts too when it's outer surface dries enhancing the change in focus.

As far as drops there are several, dyes to detect corneal damage, or tear film, pupil dilation, etc. Depends on the drops used, however if they were dilator drops you'd probably notice, I once had them middle of June blazing sun at 4:00 pm (forgot my sunglasses) just a few blocks from home, but they were all heading West. Looked like the photon burst from a nuclear explosion all the way home.

The purpose of the drops is to dilate your pupils so your doctor can perform a DFE Dilated Fundus Exam. This test examines your Retina for signs of eye issues like Diabetes, Macular Degeneration and other irregularities.

Not all drops dilate your pupils...some are for glaucoma testing.

Those are anesthetic for a Goldmann Tonometer which is the gold standard for measuring IOP (Intraocular Pressure). If your IOP is too high you may have Glucoma. The air puff Tonometer (Non Contact Tonometer) is strictly for screening. and if it detects a high pressure your doctor will apply anesthetic drops for a further test with an instrument that directly touches your eye and is much more accurate.

I got the anesthetic drops at my last exam, as well as the dilator drops. They really work, I would swear nothing ever touched my eye.
