Eye Health Library / Eye Exam & Diagnoses
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. Find a doctor of optometry near you and call for your appointment today.
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.
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 balls 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:
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.
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:
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.
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:
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.
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:
