Eye Care & Neuro-Optometry FAQs
Vision concerns can involve more than blurred eyesight. Headaches, dizziness, reading difficulty, dry eye, and symptoms following a concussion may also warrant an assessment.
Warden Optometry and Neuro Vision provides family eye care, vision therapy, and neuro-optometric services in Markham. Browse the questions below, or contact our team if you are unsure which appointment to request.
Concussions, Dizziness & Neuro-Visual Care
Yes. A standard eye chart measures visual clarity, while a concussion may affect focusing, tracking, eye coordination, motion processing, and spatial awareness. These changes can make reading, screen use, driving, or busy environments uncomfortable.
Symptoms may include:
• Blurred or double vision
• Headaches during visual tasks
• Light or motion sensitivity
• Dizziness or poor balance
• Difficulty reading or concentrating
• Visual fatigue
• Reduced tolerance for screens
Symptoms can begin immediately or become more noticeable when you return to work, school, driving, or other visually demanding activities.
Anyone with a suspected concussion should receive an appropriate medical assessment. A neuro-optometric evaluation focuses specifically on how the injury may have affected visual function.
Consider an evaluation if visual symptoms continue after a concussion, whiplash, brain injury, stroke, or neurological illness. An assessment may also be appropriate if reading, screens, movement, or visually busy environments repeatedly trigger symptoms.
Vision helps the brain interpret movement and understand where the body is in space. Difficulty with eye coordination or visual processing may contribute to dizziness, motion sensitivity, or feeling unsteady.
Dizziness can have many possible causes. A neuro-optometric assessment examines visual contributors and does not replace medical or vestibular evaluation.
Busy environments contain movement, patterns, changing light, and large amounts of visual information. If your visual system has difficulty processing motion or complex scenes, stores, crowds, traffic, or scrolling may feel disorienting.
Binocular vision dysfunction occurs when the two eyes have difficulty working together comfortably. It may contribute to headaches, eyestrain, double vision, dizziness, reading difficulty, or discomfort during screen use.
A binocular vision assessment evaluates skills such as eye teaming, focusing, alignment, and tracking.
Care may use guided visual activities to address skills affected by an injury or neurological condition. Depending on your assessment, treatment may work on tracking, focusing, eye coordination, visual processing, motion tolerance, or visual-vestibular integration.
The length of care varies according to your findings, symptoms, goals, and response to treatment.
Some people experience blurred vision, visual fatigue, dizziness, light sensitivity, screen intolerance, or difficulty concentrating after COVID. A neuro-optometric evaluation can determine whether a functional vision problem may be contributing to these symptoms.
Seek immediate medical care for warning signs such as:
• Loss of consciousness
• Seizure
• Repeated vomiting
• A severe or worsening headache
• Neck pain or tenderness
• Weakness or tingling in the arms or legs
• Increasing confusion
• Double vision following an injury
Anyone with a suspected concussion should stop the activity and seek medical attention.
Eye Exams & Eye Health
Yes. A comprehensive eye exam assesses your visual clarity, prescription, eye coordination, and eye health. Depending on your needs, testing may include retinal imaging, OCT scans, visual field testing, or other diagnostic technology.
Your recommended schedule depends on your age, eye health, medical history, prescription, and risk factors. Children, older adults, and patients with diabetes, glaucoma, cataracts, or other eye conditions may need more frequent monitoring.
Yes. Conditions such as glaucoma, diabetic eye disease, and some retinal problems may develop before you notice a change in vision. Regular eye exams support earlier detection and ongoing monitoring.
Contact the clinic promptly if you experience sudden vision loss, severe eye pain, new flashes or floaters, an eye injury, marked redness, or discharge. If you are unsure how urgent the problem is, call the office for guidance.
Children's Vision & Myopia Care
Yes. A screening checks selected aspects of vision and does not replace a comprehensive eye exam. An exam can assess eye health, prescription, focusing, eye teaming, tracking, and other visual skills used for reading and learning.
Possible signs include:
• Squinting or holding materials very close
• Frequent headaches
• Covering one eye
• Losing their place while reading
• Avoiding close work
• Tiring quickly during homework
• Difficulty seeing the board
Some children do not report symptoms because they assume everyone sees the same way they do.
Myopia management uses specialized treatment and regular monitoring to help slow the progression of childhood nearsightedness. Recommendations may include ortho-k, specialty spectacle lenses, or soft contact lenses, depending on the child's eyes and needs.
Ortho-k lenses are custom rigid contact lenses worn overnight. They temporarily reshape the front surface of the eye to provide clear daytime vision without glasses or daytime contacts. For suitable children, ortho-k may also form part of a myopia management plan.
Vision therapy is a structured program that works on specific visual skills, such as focusing, tracking, eye teaming, and visual processing. It may be recommended when an assessment identifies a functional vision difficulty that could benefit from treatment.
Dry Eye, Screens & Contact Lenses
Watery eyes can respond to irritation or an unstable tear film. These reflex tears may not provide the balanced lubrication your eyes need. A dry eye evaluation can help identify what is contributing to your symptoms.
Long periods of screen use place sustained demands on focusing and eye coordination while often reducing how frequently you blink. This may contribute to headaches, dryness, blurred vision, or tired eyes. An eye exam can check for prescription, tear-film, focusing, or eye-coordination concerns.
Yes. A contact lens exam evaluates how a lens fits and interacts with your cornea and tear film. It also helps determine the appropriate lens material, size, design, and replacement schedule.
Some people with dry eye can wear contact lenses comfortably with the right lens and a plan to manage dryness. Your eye doctor can evaluate your tear film and eye surface before recommending suitable options.
Appointments, Referrals & Insurance
Referral requirements may depend on the service or your insurance plan. Contact the clinic to discuss your symptoms and confirm whether you need to bring a referral or other documentation.
Bring your current glasses or contact lenses, a list of medications, insurance information, and any relevant eye or medical reports. For post-injury care, records from other members of your health care team may provide helpful context.
Coverage depends on the service and your individual insurance plan. Some accident-related services may qualify for automobile insurance benefits. Contact your insurer to confirm eligibility, limits, deductibles, and referral requirements.
The team at Warden Optometry and Neuro Vision can help explain the documentation and payment process, although final coverage decisions are made by your insurer.
