Correction of night myopia and glare for night driving.
OBJECTIVE
To assess the effectiveness of treating night myopia.


METHODS
Ophthalmic practice in Toronto.


METHODS
Sixty-one patients aged 18 to 60 years with night myopia and no ocular disease followed for 1 to 14 months (phase 2). Phase 1 (32 patients) was abandoned because of problems with the tint chosen.


METHODS
Assessment of night myopia with a laser speckle generator, prescription of minus lenses with or without a tint.


METHODS
Magnitude of night myopia, subjective change in symptoms of night myopia.


RESULTS
Nineteen patients (31%) could not benefit from minus or tinted lenses, and eight were lost to follow-up. Of the remaining 34 patients 22 (65%) reported marked improvement in night driving, 9 (26%) had moderate improvement and 3 (9%) had minimal improvement.


CONCLUSIONS
Many patients with night driving difficulties can be helped with an increased myopic correction worn at night.
