Here are some helpful resources to learn more about vision development:
- The infantSEE program is a national public health service where a doctor of optometry (OD) performs a no-cost vision assessment of babies between ages of 6-12 months of age. The infantSEE program has great information for parents on their website: infantsee.org
- The American Optometric Association (AOA) has guidelines for testing and treatment of our little pediatric patients. Do you know the first eye examination should take place between ages 6-12 months and the second at age 3? The AOA Parents Center is packed with information. To learn about vision from birth to age 24 months, visit AOA Infant Vision.
- To learn more about preschool vision development, visit AOA Preschool Vision
- Dr. Lynn Hellerstein, a personal friend and colleague blogged about her granddaughter Edina’s Visual development at each age and stage. This great series includes videos, milestones, and observations. Learn more here: https://www.lynnhellerstein.com/category/vision-development-through-edinas-eyes/
- All about Vision is a helpful website for families to learn more about children’s vision: https://www.allaboutvision.com/parents/infants.htm
I also highly recommend the following book for parents:
Active Baby, Healthy Brain: 135 Fun Exercises and Activities to Maximize Your Child’s Brain Development from Birth Through Age 5 by Margaret Sassé
What does a baby see?
Symptoms of refractive errors vary per individual and may include: – headache – fatigue – eye strain – squinting – blurred or distorted images, up close and/or in the distance
My colleague Sarah Lane, OD, FCOVD has some great videos on helping your child’s sensory (sight, touch, balance, pressure, hearing) and motor (movement of the body) systems development here:

When: Sunday, February 23, 2020 from 9:00 AM to 12:00 PM (MST)
Where: Hellerstein & Brenner Vision Center, P.C.7400 East Orchard RoadSuite 175-SGreenwood Village, CO 80111
Topic: Testing and Treatment of Vertical Deviations
Presentors: Dr. Jennifer Simonson of Boulder Valley Vision Therapy and Dr. Lynn Hellerstein of Hellerstein & Brenner Vision Center, P.C.
Course Description: Dr. Simonson and Dr. Hellerstein will share clinical pearls in treating vertical diplopia. This course will discuss eye alignment, prism prescribing, and recommended vision therapy techniques to decrease symptoms of double vision. The goal is of this course will be to utilize compensatory and therapeutic strategies to improve fusion skills for patients with vertical strabismus and diplopia. During this workshop, attendees will complete hands-on training on clinical testing for vertical misalignment. Stations will include Maddox rod, Modified Thorington, laser-assisted Hess Lancaster, and other clinical techniques to measure the amplitude of misalignment and fusional ability. This training will help vision therapists understand the direction and amplitude of strabismus. Attendees will also experience induced vertical misalignment and determine optimal prism perscription based on findings. In addition, vision training concepts and procedures will be performed to increase the accuracy, stability, and concomitancy of eye alignment. Learn new techniques and appropriate procedure modifications.
Course is APPROVED for 3 hours of Colorado State licensure CE credit through COA.

Location: Barclay Lodge, YMCA of the Rockies, Estes Park, Colorado
This event is held next to Rocky Mountain National Park. The closest airport is Denver International Airport. I recommend renting a car for the 2 hr(ish) drive. Fastest route takes the E-470 Toll Road. If you have more time, take Pena to 36 and visit Pearl Street in Boulder, CO for lunch on your way up. There are also several restaurants in the City of Estes Park, Colorado. Even more time? visit the National Park for a hike or scenic drive. Our event starts with dinner at 5 pm at the Barclay lodge.
