Summary
The comparative efficacy of the duochrome test versus +1 blur test in detecting refractive errors across different ages remains under-explored in current ophthalmic research. While the duochrome test is widely used to refine prescriptions, its standalone effectiveness compared to +1 blur test based refraction has not been thoroughly investigated.
