How Important Is An Annual Eye Health Exam?

Can You See What’s Inside The Red Dots?

The Answer Is Eyes! Why is it important to get annual eye exams? Well…

Doctors of optometry play an essential and ongoing role in ensuring the health of you and your family. We diagnose, treat and help prevent diseases and disorders affecting the visual system, the eye and related structures. We also assist in identifying general health conditions that are often first detected through an eye exam, provide referrals to specialists and can help manage post-eye-surgery health. From infants to grade-schoolers through to grandparents, doctors of optometry not only ensure quality of vision and eye health, but quality of life.

As doctors of optometry, we evaluate many factors that can affect your vision and eye health. We review your case history, conduct an external and internal exam of your eyes and measure vision qualities, such as eye movements and coordination, sharpness of vision and peripheral vision. We also evaluate your ability to adjust focus and to see colour and depth normally. If we detect problems, we may recommend glasses, contact lenses, exercises, medication or surgery.

Many serious eye conditions don’t have obvious symptoms. Some eye diseases only show symptoms when the condition is advanced and difficult, or even impossible to treat. A comprehensive eye exam provides the full assurance of vision and eye health that a store sight test or a school vision screening cannot. A sight test can only determine a lens power by relying on a combination of computerized tests using automated equipment. These automated sight tests are not comprehensive or accurate and do nothing to determine if your eyes are healthy.

Your vision is priceless. Routine eye exams by a doctor of optometry not only ensure good vision and eye health, but peace of mind. If you don’t already have a doctor of optometry, you don’t need a referral to book an exam. Click Here to find a doctor of optometry near you and call for your appointment today.

At what age should you get an eye exam? At all ages. See below for different ages that should receive a comprehensive eye health exam. Detecting problems early is very important.

Infants (six months or younger):

At birth, your baby can see blurred patterns of light and dark. During their first four months, their vision will extend from an arm’s length to across a room. By their sixth month, your baby will acquire eye movement control and develop hand-eye coordination skills.

For the first six months, an infant’s eyes can appear slightly crossed or out of alignment, but if your infant’s eyes appear significantly crossed or remain misaligned after six months of age, contact your doctor of optometry right away. Your child may have strabismus, commonly known as crossed eyes, a condition that can be treated with eyeglasses, contact lenses, prisms, patching and/or vision therapy and in some cases, surgery. If left untreated, the ignored eye will be unable to function normally. This may result in the development of a lazy eye or amblyopia. This condition describes weak vision or vision loss in one eye as a result of an uncorrected prescription, or misalignment of the eye. If detected and treated before eight years of age, it will often resolve completely. Untreated, amblyopia can lead to significant vision loss in the affected eye.

Visual abilities play a key role in early development. Doctors of optometry recommend infants have their first eye exam at six months of age and then annually after that. A doctor of optometry can complete an eye exam even if your child doesn’t know their ABC’s. A doctor of optometry can use shapes, pictures and other child-friendly ways to evaluate vision and eye health.

Preschoolers:

Between ages one and two, it’s important for a child to develop good hand-eye coordination and depth perception. There are activities that can help improve these essential visual skills, such as playing with building blocks or objects of any shape and size.

Children at age two enjoy listening to and telling stories. It helps them develop visualization skills and prepares them for learning to read. At this stage of their development, toddlers also like to paint, draw and colour, sort shapes and sizes and fit or assemble pieces. These activities are all integral to their visual development. A preschooler’s eyes are not ready for prolonged or intense concentration at short distances, but they do enjoy TV. To make TV viewing easier on the eyes, the room should be softly lit, the television placed to avoid glare and the child should sit further away than five times the screen’s width, taking periodic breaks from staring at the screen.

Be alert for symptoms that may indicate your child has a visual problem:

  • red, itchy or watering eyes
  • sensitivity to light
  • an eye that consistently turns in or out
  • squinting, rubbing the eyes, or excessive blinking
  • a lack of concentration
  • covering or closing one eye
  • irritability or short attention span
  • holding objects too close
  • avoiding books and television
  • visible frustration or grimacing
  • headaches

Protect your child’s vision. If you notice any of these symptoms, book an eye exam with a doctor of optometry. Your child should have a complete optometric eye exam between six and nine months of age. Children should have at least one eye exam between the ages of two and five and yearly after starting school. Remember, Children 19 and under are valid for a full eye exam every year under OHIP.

School-age children:

A school-age child’s eyes are constantly in use in the classroom and at play. For school-age children, several different visual skills must work together so they can see and understand clearly. If any of these visual skills are lacking or impaired, your child will need to work harder and may develop headaches or fatigue. Increased visual demands at school can point out a vision problem that was not apparent before school. The child may not realize they have a vision problem; they may simply assume everyone sees the way they do.

A vision-related problem may cause some of the symptoms described below:

  • headaches or irritability
  • avoidance of near or distance work
  • covering or rubbing of the eyes
  • tilting of the head or unusual posture
  • using a finger to maintain place while reading
  • losing place while reading
  • omitting or confusing words when reading
  • performing below their potential

Conditions that may emerge during this stage in your child’s life include myopia or nearsightedness (blurred vision when seeing objects at a distance), hyperopia or farsightedness (blurred vision when seeing objects up close) and astigmatism (distorted vision at all distances). Protect your child’s vision. If you notice any of these symptoms, book an eye exam with a doctor of optometry. Your child should have at least one eye exam between the ages of two and five and yearly after starting school.

Adults:

For adults, a regular eye exam is an important part of maintaining your overall health and making your vision last a lifetime. Without an eye exam, critical health issues can be overlooked until it’s too late.

Our eyes change as we age. In particular, people over the age of 40 may be at an increased risk for age-related eye conditions, some of which may have no visible symptoms until the condition is advanced and difficult, or even impossible, to treat. The most common eye problems among adults include:

  • Presbyopia: a natural effect of aging in which the ability to focus on close objects decreases over time. Presbyopia can cause headaches, blurred vision and the need for more light or sore eyes.
  • Cataracts: distorted or cloudy vision caused by the lens inside the eye losing its transparency over time. Cataracts can require changes to your glasses or surgical removal.
  • Diabetic Retinopathy: a weakening or swelling of the tiny blood vessels in the retina of your eye and the growth of new blood vessels resulting in blood leakage and other changes. If left untreated, blindness can result.
  • Macular degeneration: a disease that results in degenerative changes to your central vision and is a leading cause of vision loss among older adults.
  • Glaucoma: a silent thief that often has no symptoms until significant damage has occurred. Glaucoma is caused by elevated pressure within the eye and can lead to serious vision loss if not detected and treated at an early stage.

Your eyes are also windows to your overall health and an eye exam can also uncover underlying and life-threatening health issues, such as Type 2 diabetes, high blood pressure, certain vascular diseases and brain or eye tumors. Adults aged 19 to 64 should have an eye exam at least once every two years and people with diabetes should have an exam at least once a year. Other health conditions may also warrant more frequent eye examinations.

Seniors:

As most people age, their vision needs change. Complications often arise and getting expert care from a doctor of optometry is critical.

At age 65 and older, adults should have an eye exam at least once a year. A comprehensive eye health examination should be the key to preserving your vision and making it last a lifetime. Regular exams conducted by your doctor of optometry give you peace of mind in knowing that your eyes are being treated by an eye health professional that can identify potential health issues early. Early identification and treatment of conditions that can often have no visible symptoms is key to protecting your sight.

Adults aged 65 or older are at a higher risk for a number of eye conditions and diseases that can threaten your sight, including:

How exposure to blue light affects your brain and body

Looking at your phone for a long period of time at night is not going to help your body feel ready for the next day. Exposure to blue light confuses the brain as it mimics the brightness of the sun. This causes the brain to stop producing melatonin, a hormone that gives your body cues to sleep.

Affects of smartphone light:

  1. Disrupt your sleep cycle, which might leave you distracted and impair your memory the next day
  2. Poor night’s sleep can make it harder to learn
  3. Lack of sleep overtime can lead to neurotoxin buildup that makes it harder to get good sleep
  4. Suppressed melatonin levels by blue light exposure are more prone to depression
  5. Disrupting melatonin and sleep can also affect hormones that control hunger, which increases the risk of obesity
  6. Light exposure at night has a connection to increased risk of breast and prostate cancer
  7. Researchers are suspecting that blue light can lead to cataracts
  8. Researchers also indicate that long term exposure can harm the retina

Solutions:

  1. Discuss with your Optometrist or eye care professional about high energy blue light
  2. Invest in lenses with coatings that block out blue light (Essilor, Nikon, Kodak, Hoya, Zeiss)
  3. Invest in BlueTech Lenses

Enhanced Performance

Ensure you’re seeing the best to perform and visit your eye care professional. Understanding and resolving your visual needs will give you the confidence and ability to improve in your daily activities. A comprehensive eye health examination can make a big difference in an individual’s life. The goal is to ensure you’re seeing the best for success.

In the video below, Eye Associates of Don Mills’ patient, Phil Watanabe, is a professional financial stock trader and ultimate player for the Toronto Rush. He understands the importance of clear vision and wears contact lenses and eyeglasses to be able to perform on and off the field. Contact lenses, sport goggles, and vision correction surgery are great solutions for athletes who require vision correction.

Other solutions is Vision Therapy (often called “VT”), which involves activities and procedures specifically designed to improve a patient’s visual skills and visual performance. These activities and challenges are designed and delivered by certified Optometrists. Eating healthy, exercising, and protecting your eyes from the sun are also great tips to preserve visual performance. Talk to your Optometrist to learn more pro tips to enhance your visual performance.

Tunnel Vision

What is tunnel vision? Moderate and severe cases of peripheral vision loss create the sensation of seeing through a narrow tube, a condition commonly referred to as “tunnel vision.” Symptoms of peripheral vision loss also can include difficulty seeing in dim light and decreased ability to navigate while you are walking.

A common cause of loss of peripheral vision (also called a peripheral field defect) is optic nerve damage from glaucoma. Eye “strokes” (occlusions) that block normal blood flow to the eye’s internal structures, including the optic nerve, also can lead to loss of peripheral vision. A stroke or injury also may damage portions of the brain where images are processed, leading to blind spots in the visual field.

If you suspect you have lost peripheral vision, see your eye doctor for a comprehensive eye exam that includes visual field testing. If you have a sudden decrease in peripheral vision, see your eye doctor immediately. Sudden loss of peripheral vision may indicate a detached retina, which is a medical emergency that must be treated as soon as possible to avoid permanent vision loss.

Gift of Sight

Being able to see the colours of life gives you wonderful opportunities. Your vision of the world is important to your success. Never lose sight of it. “She went to the pediatrician and they did a little machine that said she had some astigmatism higher than normal. So they said when can I get her checked out. She hasn’t crawled yet, and I thought maybe there was something wrong with her eyesight so I examined her. She doesn’t have an astigmatism, but she is +7.00 in one eye and +5.00 in the other. The doctor said that is more than likely why she hasn’t crawled.” Thank your Doctor of Optometry, Optician and/or Opthalmologist for being able to see beautiful moments like this everyday.
