How does the eye work?
Answer: When you take a picture with a camera, the lens in the front of the camera allows light to pass through and focus that light on the film that covers the back side of the camera. A picture is taken when the light hits the film. Our eyes work in a very similar way. The front of the eye (the cornea, pupil and lens) is clear, which allows light to pass through. The cornea and lens of the eye focuses the light on the back wall of the eye, the retina. Like the film, the retina is the “seeing” tissue of the eye, sending messages to the brain through the optic nerve, allowing us to see.
When should my child’s eyes be examined?
Answer: The American Academy of Ophthalmology and the American Academy of Pediatrics recommend that the first vision screening be conducted for a newborn prior to being discharged from the hospital. Visual function will be monitored by your child’s pediatrician during well-child exams (usually at two, four and six months of age). If there are any signs of an eye condition, your child may be referred to an ophthalmologist. Beginning at three years of age (and yearly after five years of age), amblyopia (poor vision in an otherwise normal appearing eye), refractive and alignment screenings should take place. If you notice any signs of decreased vision or misalignment of the eye, please contact your ophthalmologist for a complete eye examination.

What is the difference between an ophthalmologist and an optometrist?
Answer: Ophthalmologists are the experts in the diagnosis and treatment of diseases of the eye and in the surgical treatment of the eyes. Ophthalmologists go through medical school and typically complete 4 to 5 more years of training than Optometrists do. Optometrists are the experts in prescribing glasses and contact lenses. Optometrists complete 4 years of preoptometry education and then are specifically educated in an accredited optometry college for four more years, but they do not attend medical school. Optometry school is similar to podiatry school or chiropractic school in that it does result in a doctor's degree but outside of medical school. Optometrists are not licensed to perform surgical eye treatment procedures except in a very few states.
What is legal blindness?
Answer: Perfect vision is 20/20. A person is legally blind when their better eye’s best corrected visual acuity is equal to or less than 20/200. A person can also be legally blind if their side vision in their better eye is narrowed to 20 degrees or less. Although someone may be legally blind, some vision still may be useful and helpful for everyday life. Legally blind people may qualify for certain government benefits.
