The structures of the eye include the cornea, iris, pupil, macula, retina, and the optic nerve.
Light enters the eye through the cornea and passes through the pupil. It then hits the lens. This focuses the light rays on the retina. The optic nerve carries the image from the retina to the brain.
Detailed information on a child's vision milestones
An ophthalmologist is either a medical doctor (M.D.) or an osteopathic physician (D.O.). An optometrist is a doctor of optometry (O.D.) but is not a medical doctor. An optician is a technician who fits eyeglasses.
Many types of vision tests can be used to check your child's ability to see. Some of them can be used at any age, and some are used based on your child's age and understanding.
Symptoms of eye problems in children include crossed eyes, redness in the eyes, squinting, and excessive tearing.
Eye disorders in children are either refractive or nonrefractive errors. Refractive errors are those caused by the shape of the eye. Nonrefractive errors are caused by disease.
The most common refractive errors in children are nearsightedness, farsightedness, and astigmatism.
Strabismus is a misalignment of the eyes. The eyes (one or both) may turn inward, outward, up, or down. This condition is also called wandering eye or crossed eyes.
Healthcare providers who specialize in children's eye care say children usually become near- or farsighted between ages 6 and 12. But even infants can wear glasses if they need help to see well.
A child who needs vision correction may wear eyeglasses or contact lenses. Either choice comes in a range of choices.
Children should wear protective eyewear during sports and recreational activities. In the classroom, they should wear eye protection when doing lab experiments.
A child with a foreign object in the eye should not rub the eye. An eye wash may be able to flush the object out of the eye. If that doesn't work, seek medical attention immediately.
Cosmetics are among some of the most common sources of problems for contact lens wearers. Misusing cosmetics can lead to severe harmful reactions.
