Vision Screening

Visual health is an important part of a child’s overall health and well-being. Proper vision is important for a child’s movement and coordination, independence, play and learning. If left untreated, vision problems may become serious and prevent a child from reaching their full potential.

Wellington-Dufferin-Guelph Public Health is partnering with our local Lions Clubs to offer school-based vision screening to senior kindergarten (SK) students according to the Child Visual Health and Vision Screening Protocol, 2018 of the Ontario Public Health Standards (2018).

What is vision screening?

Vision screening is a series of three short and simple tests that can identify some risk factors for certain vision disorders.

It is a free service that is offered in the school-setting to SK students on a yearly basis.

Vision screening does not replace the need for a full exam by an eye doctor on a yearly basis or whenever there is a concern. Children and youth (0 - 19 years old) are eligible for a free exam by an eye doctor every 12 months through OHIP (Ontario health card). Visit the College of Optometrists of Ontario to find a local optometrist.

Why is vision screening important?

Young children may not know they have a vision problem because they assume everyone sees like they do. Vision screening is an effective and non-invasive way to identify children with potential vision problems and refer them to the eye doctor for a free comprehensive eye exam. It is important for vision problems to be caught and treated early so that children can see and learn to the best of their ability.

What vision screening tests are used?

The following three (3) vision screening tests are used:

  1. HOTV visual acuity chart (letter book) – this test measures sharpness of eyesight/clarity of vision.
    HOTV visual acuity chart
  2. Randot Preschool Stereotest (3D picture book) – this test measures the ability to recognize depth.

    Randot Preschool Stereotest (3D picture book)

  3. Autorefractor (automated camera) – this test automatically screens for some refractive errors such as near and farsightedness.


If my child wears glasses, do they need to be screened?

Children wearing glasses will still be screened using the HOTV visual acuity chart and the Randot Preschool Stereotest. They will leave their glasses on for these tests.

How will parents be notified that vision screening is being offered at their child’s school?

Parents and guardians of children in SK will receive a notification that the screening is taking place at their child’s school at least 10 business days in advance of the screening date.

What happens after a child has been screened? 

Parents and guardians of all children screened will receive a Parent Notification Form that notes their child’s overall result (i.e. PASS or REFER) with  recommended next steps.

Parents and guardians of children screened whose overall screening result is a REFER, will receive a Reminder Letter within 20 business days of the screening date.

What is a comprehensive eye exam?

A comprehensive eye exam is a  full assessment of the eye and vision system. This service includes:

  • Reviewing child’s health history and the family history of eye problems
  • Checking visual acuity and 3D vision
  • Checking eye alignment
  • Checking eye focusing ability
  • Checking eye health (i.e. allergies, infections)
  • Identifying if the child is meeting visual developmental milestones
  • Determination of need for eye glasses or other treatment (i.e. eye drops, vision therapy, a referral to a healthcare provider, etc.)

Vision screening cannot diagnose vision disorders, and it is NOT a replacement for a comprehensive eye exam by an eye doctor.

How often should an infant or child go to the eye doctor?

The Ontario Association of Optometrists recommends that all children have their first eye exam at 6 months old, again at 3 years old, and every year after that.

Children and youth (0-19 years old) are eligible for a free exam by an eye doctor every 12 months through OHIP (Ontario health card).

For more information on exams for infants and children, please visit the Ontario Association of Optometrists website.

We don’t currently have a family eye doctor. Can you help?

You can search for an eye doctor in your area through the College of Optometrists of Ontario or the Ontario Association of Optometrists.
