Subjective Refraction is an attempt to determine, by trial and error using the patient’s cooperation, the combination of lenses that will provide the best corrected visual acuity (BCVA).[1] It is a clinical examination used by orthoptists, optometrists and ophthalmologists to determine a patient's need for refractive correction, in the form of glasses or contact lenses. The aim is to improve current unaided vision or vision with current glasses.

He or his predecessor may grudgingly forgive the French for this ganged-up-against-us, global-conspiracy against die-hard believers -- this colossal sin and unprecendent annihilation of our basic, fundamental religious right -- for not letting our girls wear scarf.

Take off those trial frames.
