Often yes. Dialating the eyes will give the Optometrist a more accurate idea of the prescription. As you can imagine, some children do not want to wear glasses because they are afraid of being bullied, others may want glasses because their friends have them so they are not always completely honest during a sight test! Amblyopia can only be treated effectively from a young age so it is very important to have childrens eyes tested regularly.
why are careful, accurate observations necessary in chemistry practical work.
It's necessary for navigation. Knowing exactly what time specific stars rise or set tells you your longitude.
You need to specify which oil for a more accurate answer. Most oils have a refractive index near 1.47 So 3 * 108 / 1.47 = 2.04081633 * 108 m/s

They are necessary for accurate chemical calculations.

It is a computer-controlled machine that is used by optometrists during an eye exam to determine the refractive error and to prescribe the accurate lens type for that person.
No, it causes accurate results for amphetamines.
To ensure your first trial was accurate
B. accurate chemical calculations
Because you need to be able to be as accurate as you can.

It would be more accurate to say that there are prescription drugs that can be used to treat pain. Since pain is a symptom and not a disease, it does not get cured, only treated. If you cure the disease, then you will also eliminate the pain caused by that disease.
