Result: Females were more compliant than males.51 out of 94 patients practiced the rule and among those 56% showed mild improvement of symptoms. Avg. score who practiced was 7.74 ± 3.73 at presentation and 6.37 ± 2.64 after 3 months

Conclusion: Efficacy of 20/20/20 rule is equivocal. Rule’s clinical impact can be described as marginal. the feasibility of its use is questionable .The Rule at best will offer only brief symptomatic relief.
