Different people should receive complete eye exams at different intervals. Children’s eyes should be examined at six months of age, three years of age, and six or seven years of age and every two years during school days, since high vision problem rates are reported among both preschool and school-aged children. For children with risk factors of vision problems such as prematurity, developmental delays, turned eyes, family history of eye diseases and history of eye injury, more frequent eye exams are necessary.
Adults at different ages need eye exams in different frequencies. Based on American Optometric Association (AOA), among people less than 40 years old, one exam every two or three years is enough for those with normal vision, while an annual exam is required for those wearing eyeglasses or contacts. People with diabetes, high blood pressure and other disorders may also require more frequent eye exams. People above 40 need eye exams every one to two years and people over 60 need annual exams, in case of age-related problems such as presbyopia, cataracts and macular degeneration.
In the United States, ophthalmologists, optometrists, as well as opticians can conduct regular eye exams. Ophthalmologists are the most professional since they are exclusively licensed to perform eye surgeries. Optometrists can prescribe certain medications and minor surgical procedures, while opticians are only entitled to adjust and repair glasses, or fit your contacts.
A basic complete eye exam should contain several items: family eye history review, distance and near vision evaluation, current eye prescription determination, eye coordination evaluation and internal and external eye healthy examination. You should be clear of all these items as well as the exact charge at the time you make an appointment with your doctor. Exam fees for contact lens fitting, laser-surgery evaluation and pediatric testing are higher than that of regular exams. You should check your vision insurance benefits for potential discount, since exam fees vary widely from discount outlets to surgical offices.
For better exam results, you need to take necessary documents and cards of yourself and your family members. Your vision insurance card is needed if you want to get any discount. For your eyes full evaluation, your major medical health care cards and recent prescription glasses or contacts may be useful to provide additional eye exam aspects. A list of your prescription medications can help the doctor learn your complete health history. Of course, you can bring your interested questions.
