So let's talk more nuts and bolts about the OPs question.
Lets see. So the OP has an interest in medication, patient interaction, being a doctor, diagnosing, improving sight, and possibly working for a pharmaceutical company for vision meds.
Passion4Sci is steering the OP away from optometry because he thinks compared to pharmacy, the knowledge of an optometrist is less appropriate for what the OP desires to do, compared to a pharmacist.
That's fine. So perhaps Passion4Sci can explain to us what he knows about vision? I didn't realize he acquired expertise in vision during his pharmacy training. Perhaps he can remind me of the meaning of 20/20? Or explain to me what is astigmatism? Or tell me how to measure the prescription of his glasses? Or demonstrate to us what optometric examination equipment he knows how to use? I didn't realize P4Sci received training in the ophthalmoscope during his pharmaceutical studies.
Regarding the nuts and bolts....
I doubt that what has been posted here is far from what is expected when one posts a thread entitled "Pharmacy or optometry career?" in a pre-pharmacy forum. There are people like chemguy who have experiences with the optometry and pharmacy fields, but then you have a large number of people who have limited experience with optometry. In Passion4Sci's defense, he openly admitted that he had limited knowledge of optometry, and if he has done research as a result of this thread, I believe this might have been a learning experience for him.
Now back to the nuts and bolts...
I see that you forgot to highlight the first sentence of the OP's post. It reads "I am currently a pharmaceutical sciences major and im interested in medication and how they fuction and such in the body as well." Then comes the second sentence "I am
also interested in vision and have also considered applying to optometry school." (Note the "also"). This leads me to believe that the OP's primary interest is in pharmacology/medicinal chemistry (drug research, development, etc.), and that all that stuff you highlighted in bold (i.e. patient interaction, being a doctor, diagnosing, improving sight, and possibly working for a pharmaceutical company for vision meds) is secondary.
Now about the meaning of 20/20, astigmatism, measuring glass prescriptions and so forth...
I fail to see why a pharmacist cannot learn these things if he/she wanted to. I also fail to see why someone doing groundbreaking research in ocular pharmacology needs to know how to operate optometric examination equipment. Research is a collaborative effort between people with all sorts of backgrounds. As a result of this thread, I chose to do a bit more research on the field of ocular pharmacology. At this time, it seems to be a field dominated by PhDs. To put it plain and simple, if the OP's main interest is doing research, then grad school is probably the way to go. But there is nothing preventing the OP from performing research in ocular pharmacology if he/she chooses OD or PharmD instead of grad school.
Like a large number of people have done already, I suggest that the OP shadow a pharmacist, since he has said that he does not have any pharmacy experience since he has not shadowed a pharmacist and decide between OD and PharmD. Afterwards (no matter whether he chose OD or PharmD) he should consider a post doc in ocular pharmacology and/or a PhD in pharmacology, preferably in an institution where there is a strong ocular pharmacology research department. I sincerely doubt that a person with financial interest in a pharmaceutical company would also be able to practice as an optometrist without some sort of hurdle taking into account a possible conflict of interest, unless it is something like assuming the role of provider in clinical trials of investigational drugs (I don't know if there are any hurdles associated with optometrists getting involved in clinical trials).
I also suggest that the OP try to contact someone who can provide better advice, perhaps someone who is a member of the Association for Ocular Pharmacology and Therapeutics (AOPT).
All the best lesept2 in his career. I hope he has not lost hope in the childish bickering which has become this thread.
