Question: is this a 2) strong advice, 1) weak advice 0) no advice?

The US Preventive Services Task Force (USPSTF) in 2011, while agreeing with the importance of vision screening in children ages 3 to 5 years of age, concluded that the current evidence was insufficient to assess the benefits and harms of vision screening in children < 3 years of age, citing costs of false-positive rates, and concluded that screening and treatment of amblyopia later in the preschool years may be as effective as screening and treatment done earlier in life 2.
