Question 1

What is the difference between an optometrist and an ophthalmologist?

Accepted Answer

An optometrist (OD) is a doctor of optometry who provides primary eye care including comprehensive eye exams, prescribes glasses and contacts, diagnoses eye conditions, and treats many eye diseases with medications. An ophthalmologist (MD or DO) is a medical doctor who completed medical school plus ophthalmology residency and can perform eye surgery in addition to everything an optometrist does. For routine eye care, glasses, contacts, and management of common conditions, an optometrist is appropriate. Ophthalmologists are needed for surgery (cataract, LASIK, retinal surgery) and complex medical eye conditions. Many patients see optometrists for primary care and are referred to ophthalmologists when surgery or specialized treatment is needed.

Question 2

How often should I have an eye exam?

Accepted Answer

The American Optometric Association recommends comprehensive eye exams at these intervals: infants should have their first exam between 6-12 months, children ages 3-5 should have at least one exam, school-age children (6-17) should have annual exams since vision changes frequently during growth, adults ages 18-64 with no risk factors every 1-2 years, and adults 65 and older should have annual exams. More frequent exams are recommended if you have diabetes, high blood pressure, a family history of eye disease, wear contact lenses, or have any existing eye conditions. Your optometrist will recommend the appropriate schedule based on your individual risk factors.

Question 3

Do I need a separate exam for contact lenses?

Accepted Answer

Yes, a contact lens exam is separate from and in addition to a comprehensive eye exam. While your glasses prescription determines the lenses needed for distance correction, a contact lens fitting requires additional measurements of your cornea's shape and size, evaluation of your tear film quality, determination of the best lens type for your eyes and lifestyle, training on insertion, removal, and care, and follow-up visits to ensure proper fit. Contact lens prescriptions also include parameters like base curve and diameter that aren't part of a glasses prescription. The fitting fee varies based on lens complexity.

Question 4

What is a dilated eye exam and why is it important?

Accepted Answer

A dilated eye exam uses special drops to widen (dilate) your pupils, allowing the optometrist to see a much larger area of the inside of your eye, including the retina, optic nerve, and blood vessels. This is crucial for detecting conditions like glaucoma, macular degeneration, diabetic retinopathy, and even signs of high blood pressure or brain tumors that may not cause symptoms until advanced. The drops take about 20-30 minutes to work, and the effects (blurry near vision and light sensitivity) last 4-6 hours. Bring sunglasses and consider having someone drive you home. Dilation is recommended at least every 1-2 years for most adults and annually for those with diabetes or at higher risk for eye disease.

Question 5

Can optometrists prescribe medications?

Accepted Answer

Yes, optometrists in all 50 states are licensed to prescribe medications for eye conditions. This includes antibiotic drops for infections, anti-inflammatory medications, glaucoma drops to lower eye pressure, allergy eye drops, and medications for dry eye disease. The specific scope of prescriptive authority varies slightly by state, but most optometrists can prescribe the same eye medications as ophthalmologists. For chronic conditions like glaucoma, many patients receive ongoing care and prescriptions from their optometrist, who monitors the condition and adjusts treatment as needed.

Question 6

What should I bring to my eye exam?

Accepted Answer

Bring your current glasses and/or contact lenses (even if you think the prescription is outdated), your contact lens boxes or prescription for brand and specifications, a list of all medications you take (including eye drops and supplements), your vision and/or medical insurance cards, a list of any eye or vision symptoms you've been experiencing, information about your family's eye health history (glaucoma, macular degeneration, etc.), and sunglasses in case your eyes are dilated. If you have medical records from previous eye doctors, those can be helpful too. Having this information ensures a thorough exam and accurate assessment.

Question 7

Why do I need annual diabetic eye exams?

Accepted Answer

Diabetic retinopathy, the leading cause of blindness in working-age adults, often has no symptoms until significant damage has occurred. Annual dilated eye exams can detect early changes in the retinal blood vessels before you notice any vision problems. With early detection, treatments like laser therapy or injections can prevent 90% of severe vision loss. The exam also checks for other diabetes-related issues like cataracts (which develop earlier in diabetics), glaucoma, and changes indicating poor blood sugar control. Your optometrist will send a report to your primary care doctor or endocrinologist as part of your overall diabetes management.

Question 8

At what age should children have their first eye exam?

Accepted Answer

The American Optometric Association recommends a first comprehensive eye exam between 6 and 12 months of age, a second exam at age 3, another before starting school (age 5-6), and then annually throughout school years. Children don't need to know letters - optometrists use age-appropriate tests with pictures, shapes, or objective measurements that don't require responses. Early exams are crucial because 80% of learning is visual, vision problems can be mistaken for learning disabilities or attention issues, conditions like amblyopia (lazy eye) must be treated early for best outcomes, and many children don't know what 'normal' vision looks like and won't complain.

Question 9

Can an optometrist detect health problems beyond the eyes?

Accepted Answer

Yes, a comprehensive eye exam can reveal signs of over 270 systemic health conditions. The eye is the only place in the body where blood vessels and nerve tissue can be directly observed without surgery. Optometrists may detect signs of diabetes (blood vessel changes in the retina), high blood pressure (narrowing or bleeding in retinal vessels), high cholesterol (deposits in or around the eye), autoimmune diseases (inflammation patterns), certain cancers (tumors or unusual growths), neurological conditions (optic nerve changes), and thyroid disease (eye protrusion or movement issues). These findings often prompt referrals to appropriate specialists for further evaluation and treatment.

Question 10

What is the difference between vision insurance and medical insurance for eye care?

Accepted Answer

Vision insurance (like VSP or EyeMed) covers routine preventive eye care - annual exams to update glasses/contact prescriptions and provides allowances toward eyewear. It's designed for maintaining healthy vision but not treating disease. Medical insurance covers eye exams and treatment when you have a medical eye condition like dry eye disease, glaucoma, cataracts, diabetic retinopathy, eye infections, or injuries. If you come in for a routine exam and the optometrist discovers a medical condition, the visit may be billed to your medical insurance instead of or in addition to your vision plan. Some patients have both types of coverage, using vision insurance for annual wellness exams and medical insurance when problems arise.
