How Eye Doctors Determine Prescription Glasses for Babies

When it comes to babies wearing glasses, a common question often arises: How do eye doctors determine their prescription when they can’t read letters or even speak yet? This was something that I pondered when I took my daughter, Zoe, for her first eye appointment at just 9 months old. To my surprise, eye doctors have a range of tools at their disposal to accurately assess a baby’s prescription. In this article, we will explore how eye doctors use subjective and objective measurements to determine the correct prescription for babies.

Subjective Measurements: Teller Acuity Cards

One technique eye doctors use is a subjective measurement known as Teller Acuity Cards. These cards are designed based on the concept of preferential looking. Babies are naturally drawn to visually interesting objects, and in the case of these cards, the square with alternating black and white lines is the most visually stimulating part. If a baby’s vision is clear enough, they will be captivated by the square. However, if their vision is blurry, the lines will blur together, and the square will appear the same shade of grey as the rest of the card. By gradually reducing the thickness of the lines, eye doctors can determine the point at which the lines blur too much for the baby to see a separate square. This provides valuable insights into the baby’s visual acuity.

Objective Refraction: Retinoscopy

Another method eye doctors employ is objective refraction, specifically retinoscopy. The clarity of a person’s vision is influenced by the shape of their eye and the ability of the eye’s lens to focus light. For individuals who are hyperopic (farsighted or longsighted), light focuses behind the retina, while for those who are myopic (nearsighted or shortsighted), light is focused in front of the retina. By examining the shape of the eye and where the light converges, eye doctors can determine the corrective lens shape necessary to ensure proper focusing of light on the retina.

Combining Subjective and Objective Measurements

Subjective measurements such as Teller Acuity Cards require the baby’s cooperation and response. On the other hand, retinoscopy provides insights into the shape of the eye without requiring a response from the baby. Eye doctors use both methods in conjunction to arrive at the final prescription for corrective lenses. It is essential to consider other factors that affect visual acuity to ensure an accurate prescription.

For a more comprehensive understanding of the process, I consulted Dr. Dominick Maino, an experienced eye doctor and professor of Pediatrics/Binocular Vision. Dr. Maino emphasized that various techniques, including auto-refractors and retinoscopes, can be used to objectively assess refractive errors. Similarly, different tools like Teller Cards, Snellen Charts, and Lea Symbols are used to subjectively measure visual acuity. Dr. Maino emphasized the importance of equal visual acuity in both eyes rather than focusing solely on the numerical result of the test.

To prescribe glasses for babies and young children, eye doctors rely on a combination of scientific knowledge and artistic judgment. Different considerations come into play, especially for conditions like myopia and hyperopia. It is worth noting that ophthalmologists and optometrists may have differing philosophies, but when it comes to infants and toddlers, the prescription approach tends to be similar.

The key takeaway is the importance of finding a doctor whom you trust and following their advice. Seeking a second opinion is always a viable option, and it’s essential to ask plenty of questions to understand the rationale behind their recommendations. If a doctor fails to allocate enough time to address your concerns, consider finding a new one who values open communication. Remember, the well-being of your child’s eyesight is of utmost importance.
