Myopia Risk Calculator

A clinical screening tool to help parents understand their child’s risk of developing or progressing myopia — and what to do about it.

Child's Eye Health Assessment 0% complete

1. How old is your child?

2. Do any close family members (parents or siblings) wear glasses for distance?

3. How much time does your child spend outdoors each day? Outdoor light is the single most effective way to reduce myopia risk

4. How much time does your child spend on screens or close reading each day? (school + recreational combined)

5. Have you noticed any of the following? Select the most relevant option

Please answer all 5 questions before calculating.

5×

higher risk of myopia when both parents are myopic vs. neither parent (meta-analysis)

~50%

lower risk of developing myopia associated with an extra 1–1.5 hours of outdoor time per day (meta-analysis)

+67%

increased risk of myopic maculopathy per additional diopter of myopia (Bullimore & Brennan, Optom Vis Sci 2019)

+30%

Risk of Complications Compared to No Myopia

−0.50 to −3.00 D	Low myopia	~3×	~1.6×	~14×
−3.00 to −6.00 D	Moderate myopia	~9×	~3×	~73×
−6.00 D and above	High myopia	~13–20×	~3–4×	Dramatically elevated

Source: Haarman et al., IOVS 2020 (systematic review & meta-analysis). There is no truly "safe" level of myopia — even low myopia raises lifetime risk compared to no myopia.

Myopia management at Peel Eye Care is tailored to each child — there's no one-size-fits-all approach. Depending on what we find at the exam, options may include myopia-control glasses, specially designed contact lenses, low-dose eye drops, or a combination. The earlier we start, the better the long-term outcome.

Disclaimer: This is a screening tool only — not a diagnosis. Only a licensed optometrist can assess your child's vision and recommend treatment. When in doubt, book an exam.
