Various methods have been employed in an attempt to decrease the progression of myopia, although studies show mixed results. Many myopia treatment studies have a number of design drawbacks: small numbers, lack of adequate control group, and failure to mask examiners from knowledge of treatments used. Among myopia specialists, mydriatic eyedrops are the most favored approach, applied by almost 75% in North America and more than 80% in Australia. A 2015 review suggested that increased outdoor time protects young children from myopia. A 2020 study of global practice patterns used by paediatric ophthalmologists to decrease the progression of myopia showed behavioral intervention (counseling to spend more time outdoors and less time with near-work) to be favored by 25% of specialists, usually in addition to medications.
