You posted this under "Eyes and vision disorders." I'm not sure there is a disorder called untrained eye. Normally, the phrase means simply a person who is unfamiliar with whatever he or she is seeing. In other words, as an example from my line of work, a person who is not familiar with rifles or shotguns would not be able to tell as easily what caliber a gun is by looking at it as easily as someone who is familiar with them could.
"od" on a prescription for eye drops mean "right eye"--as in apply the drops to the right eye. "os" means "left eye".
it means fat
It's said that the right eye's first tear means happiness, and the left eye's first tear means sadness. But I don't know if that's scientifically proven.
The SPH in eye prescription means sphere or spherical. It indicates the measure of diopters, the lens power that is prescribed for farsightedness or nearsightedness.
It's most likely PL as in plano, Which means there is no correction.
To the untrained eye, they appear identical in both form and function.
A person with an untrained ear simply means that they cannot hear if something is out of tune or off pitch. It's similar to someone who is not trained in football or painting. They would not know if something was good or bad.
It is often mistaken because of it's shiny texture. To the untrained eye it looks very similar to gold.
Ospreys can resemble bald eagles to the untrained eye, also golden eagles can be mistaken for immature baldies.
Tilapia is a cichlid whereas bluegill are sunfish. They are not the same-nor do they taste the same-although they do look very similar to the untrained eye.
Because you have an untrained dog. Ultimately, it means you do not control your dog, your dog controls you.
It enabled untrained works to find jobs
a unbroken horse means the horse is not trained to ride. A broke horse means he is able to be ridden.
No. It will dissolve the fat in your skin though, so it appears to have similar effects on tissue to an untrained eye.
For untrained, un- is the prefix, -train- is the root, and -ed is the suffix.
No.
Depends on what the definition of "untrained runners" is. There are a lot of different things you could mean by that. If untrained means people who are out of shape and don't usually run, I'd say they are very quick at the very beginning of their races/runs and wear them selves out very quickly. The exact speed would depend on the gender, age, height and overall athleticism. Depends on what the definition of "untrained runners" is. There are a lot of different things you could mean by that.
