Signs You Might Need an Eye Exam

          Ideally, one eye exam every year should help you to stay on top of your eye health, but some people might need to schedule more than one exam in a year. Vision can change quite a bit over the course of a year, especially for those over the age of 50, and it is important to know when you need to schedule an exam.

          Here are 8 signs that you should get another exam on the calendar soon:

  1. Your eyes are red, dry, itchy, or you are seeing spots, flashes of light, or floaters.
  2. You have diabetes or another health condition that affects your eyes. Also, if you have a family history of conditions like diabetes or glaucoma you may need exams more often, especially as you move into your 50s and beyond.
  3. You can't remember when you last had an eye exam. If it’s been longer than a year, you’re overdue.
  4. You have difficulty driving at night and seeing street signs in the dark.
  5. You experience eye strain, headaches and/or blurred vision after spending an extended amount of time in front of a computer screen.
  6. You get motion sick, dizzy, or have trouble following a moving target.
  7. You hold books or the newspaper further away from your face and squint or close one eye to read them clearly.
  8. You notice any changes in your vision, especially after an incident of head trauma.

          Don't wait until you experience any of these 8 things before you schedule an eye exam. Keep in mind that an eye exam benefits more than just your eyes. Your eye doctor can detect a wide range of diseases like diabetes and cancer just by looking at your eyes.

Get an exam on the calendar, and be sure to ask your eye doctor if you should schedule more than one in a year.
Vision Screenings Are Not Eye Exams

          Vision screenings are not comprehensive eye exams. Screenings usually take only a few minutes and are often performed by volunteers who are not eye care professionals.
          In many cases, vision screenings are nothing more than a visual acuity test where you're asked to identify the smallest letters you can on a vision chart across the room.

          After a comprehensive exam, your eye doctor will discuss the findings and offer treatment options best suited to your needs.
Vision screenings typically are designed to only detect subnormal visual acuity and major vision problems — as quickly and cost-effectively as possible. They generally are ineffective for detecting more subtle vision problems and potentially sight-robbing eye diseases.
          People who fail a vision screening (usually because their visual acuity is worse than 20/40) are made aware of this and are encouraged to visit an eye doctor so they can have their vision problem professionally diagnosed and treated with eyeglasses, contact lenses, medicine or surgery.
          Eye exams, on the other hand, are performed by licensed eye doctors (an optometrist or ophthalmologist) and evaluate not only your visual acuity, but also the complete health of your eyes, from front to back — including checking for early signs of serious eye problems such as glaucoma, cataracts, macular degeneration and detached retina.
          Your eye doctor also can detect early signs of serious health problems such as diabetes, high blood pressure and risk of stroke, based on the appearance of delicate blood vessels and other structures within the eye.

Children's Vision Screenings Are Helpful — But Kids Need Eye Exams, Too

          Good vision is essential for children to reach their full academic potential. It's been widely stated that roughly 80 percent of what children learn in school is presented visually, and vision problems can have a profound effect on learning.
          According to the American Optometric Association, an estimated 20 percent of preschool children have vision problems. Other research shows that 24 percent of adolescents with correctable refractive errors (nearsightedness, farsightedness and/or astigmatism) don't have their vision fully corrected with up-to-date prescription eyeglasses or contact lenses.

Children's eye exams are important to ensure normal vision development.
         Also, children are using computers and other digital devices much more extensively and start using these devices at a much younger age than children in the past. The illuminated screens of these modern devices tend to be more visually demanding than books and other printed text.
         Increased use of digital devices by children has occurred simultaneously with another significant trend — an unprecedented increase in myopia among children in the U.S. and worldwide. These two trends have led many eye care professionals to believe computers and digital devices play an important role in the development of nearsightedness and myopia progression. This makes it more important than ever for children to have their eyes examined routinely to identify and treat vision problems.
         Vision screenings are helpful to identify children who already have significant myopia, but screenings aren't sensitive or thorough enough to identify all children who have vision problems that can affect their learning.

Passing A Vision Screening Doesn't Mean Your Child's Vision Is Perfect

         Even if your child passes a school vision screening, it doesn't guarantee he or she has perfect vision or has all the required visual skills needed for optimum performance in the classroom.
         In fact, a number of studies have identified significant challenges and shortcomings of children's vision screenings, including:
         Children with significant learning-related vision problems being able to pass simple school vision screenings
         Poor consistency of screening results among different volunteers conducting the testing
         Parents being unaware their child failed a vision screening
         Lack of follow-up to make sure children who fail screening actually have an eye exam Also, poor standardization of vision screening standards among different states and lack of reporting requirements make it impossible to adequately evaluate the effectiveness of school vision screenings.

Older Adults Need More Frequent Eye Exams

         On the other end of the age spectrum, many older Americans often forgo routine eye exams and falsely believe that free vision screenings offer adequate monitoring and protection of their eyesight.
         This is extremely dangerous, since the most common causes of blindness — glaucoma, diabetic retinopathy and macular degeneration — increase with age. Vision loss often can be prevented or reduced if these conditions are diagnosed and treated early. But the only way this can be done is to have routine comprehensive eye exams.
         Don't take chances with your eyesight as you get older. It may be sufficient to have a comprehensive eye exam every two years in your early adult life. But if you're over age 60, have an annual eye exam to preserve your vision and make sure you are seeing the world as clearly as possible. [Read more about when to have an eye exam.]
         Though Medicare does not cover routine eye exams, if you have a Medicare supplement policy or other medical or vision insurance, your benefits may include an annual comprehensive eye exam. Check with your insurance provider for details.

  1. Thanks for explaining how eyes can be affected by diabetes or other health conditions so having them examined would be important. Getting them regularly to make sure you can be aware of anything that could be affecting your health. In order to get them regularly, you’d probably want to make sure you choose a nearby optician that has hours that fit your schedule so you can make sure you have the time to go to an eye exam.

  2. Thank you for the information regarding the importance of getting eye exams as apposed to vision screenings. I think that it’s important to have an eye exam on a yearly basis to determine the health of the eyes and find any problems that may arise in that area. By having an eye exam yearly, especially when the patient is older, it reduces the chance for eye diseases to develop.

  3. I have been debating whether to bring my son in for an eye exam since he is only 4. So thank you for the information that about 20% of preschool children have problems with their vision. I will be sure to set an appointment for an eye exam soon so I can make sure my son can see as perfectly as possible.

  4. It’s good to know that I ought to consider getting an eye exam if I’m starting to get headaches or blurred vision. My wife has been having a lot of headaches lately, and we haven’t been sure why. I’ll consider getting her an eye exam to see if that will help.
