There are three types of doctors in eye care - optometrists, opticians, and ophthalmologists. Optometrists diagnose and treat vision-related concerns. You can consult an optometrist if you have blurry eyesight or headaches. Opticians are responsible for designing, repairing, making, and selling spectacles and contact lenses. Ophthalmologists diagnose and treat eye disorders and diseases. They are highly specialized doctors with years of experience who you can consult for any troubles related to the eyes.
