Jaesango, you're looking at things from the wrong perspective. There is no reason to "meet the demand of the students who want to get in." What needs to be met is the demand for optometrists by the public. That need has been met and exceeded. As Shnurek pointed out, there is currently an excess of ODs in the US. Few people argue against that point, some will say it's greater and more significant than others, but no one in their right mind will argue that there is not an oversupply of ODs in the US right now.
If someone with a 3.0 and 300 OAT really wants to go to optometry school, it's not an unreasonable feat for that student to get in. The high in my class was a 4.0 and the low was a 2.9, granted the average was about 3.6. I should mention, the guy with the 2.9 was one of the smartest people in the class. I entered my OD program with a much higher gpa, but if I studied as much as he did, I would have failed out in a month. GPA and OAT scores alone are only a portion of you as an applicant and programs know that. If you get an interview with a 3.0/300 and wow them, youll get in.
As it stands, many programs are having trouble attracting stronger applicants these days so one might argue that lower gpa/scores might be less of detriment in the future. They will never tell you that because they have to justify the ridiculous expense that you will incur in getting the degree, but it's the reality.
As someone who spent a great deal of time, money, and effort getting a degree which I would now probably choose not to get if I had the chance, I'd tell you to really look at the profession and make sure it offers you what you are looking for in its current state. Talk to practicing ODs who are recently out of school (2-5 years), and get their perspective. Talk to ODs who work in commercial/retail settings because this is where the majority of OD grads go after graduation these days. Don't just talk to ODs who have thriving private offices that were established 20 years ago. The view that they give you will be vastly different from what you might get from someone who works as an employee or independent contractor and is 3 years out. Dont rely on what the AOA tells you. Dont rely on the numbers the Bureau of Labor Stats give you, and most of all, dont rely on the ridiculous surveys put out by Money Magazine, US News, and the like. They are fed information by the AOA and private OD programs looking to fill seats with naive students who dont know what they are paying for. No one is telling you not to go into optometry, but make sure you know what it is before you sign on the dotted line. It might be very different from what you think it is.
Whether people like to admit it or not, optometry is going the way of pharmacy, towards a largely commercial profession. Optometry grads these days are flooding into commercial and retail jobs because thats where the only jobs are. As a result, the pressure of the profession is driving it toward commercial practice. Yes, a small number will get employment in private offices, but the majority end up in Walmart, Sams, Pearle, LensCrafters, Americas Best, etc. Dont take my word for it, ask new grads yourself.
Pharmacy used to be dominated by independent pharmacists who owned their own business. When you fill your prescriptions, where do you go? Do you go to a private pharmacy or do you go to CVS, RiteAid, Walgreens, etc? At one point, in another thread, I pointed out that as people flood into commercial optometry, private practice optometry shrinks smaller and smaller as a percentage of the whole. Another poster countered that claim by stating that there will then be a resultant shortage of private practices, allowing for more new grads to fill that void. Nothing could be further from the truth, in my opinion. There is no shortage of private pharmacies today despite the fact that they are a dying breed. I believe that optometry will follow the same path, unfortunately. Do your own research and come to your own conclusion. But most of all, know exactly what to expect before you decide on an OD or you might regret it down the road. Just because a degree is there and others are pursuing it doesn't mean it's a great career prospect.
