Everyone needs eye exams. Regular exams are fundamental to the long-term health of your eyes, even if you believe you have perfect vision, because they may allow your doctor to identify potentially troublesome eye conditions before they become more serious.

Most individuals should receive their first eye exam at 6 months, age 3 and then before entering the first grade, with regular exams every two years after. However, those at greater risk for eye and vision problems should have exams at a frequency recommended by their optometrist.

During the typical eye exam, an optometrist will test your vision and look for a variety of health issues. These issues may include eye-specific conditions – including cataracts and glaucoma – as well as other diseases, such as diabetes. Afterward, you’ll receive a prescription and any further instruction necessary.

Dry eyes are a common eye issue with many causes. The condition is especially common if you’re older than 50, have had laser eye surgery, are a post-menopausal woman or have a range of medical conditions, including diabetes, arthritis, lupus or thyroid disorders. Other causes can include long periods of outdoor work or exposure to computer screens. If you’re experiencing frequent or lasting irritation, it’s important to discuss dry eyes with your optometrist.
