Optometrist vs Cardiologist Which one is good profession..What are benefits and disadvantage of chosing these professions..?

An Optometrist is not an MD, but rather a Doctor of Optometry (OD) trained in diagnosis and treatment of vision problems, such as near and far-sightedness, and in most states, have a limited list of drugs they can administer or prescribe. A cardiologist is an MD trained in the specialty of Cardiology, which requires six to eight more years of training beyond the initial four years. Focusing on sub-specialties such as pediatric cardiology, may carry additional educational burdens. Both jobs pay well, but an Optometrist typically works independently or with a partner, and may work longer hours due to the additional administrative tasks of running one's own office. The demand for well-trained optometrists is growing in the United States due to the need to service the aging Baby-Boomer population. A Cardiologist, on the other hand, must usually work grinding, extended shifts during training, but the payoff in terms of salary he or she can command following successful training and board certification, can be significant. Both are Excellent careers, which require dedication and very hard work to accomplish, and can be very rewarding not only in terms of monetary gain, but in the ability to help large segments of the population as well.
