During night time I'm not able to drive because when I wear my progressive spectacles I'm able to see additional 4 images. for example: when I see a red signal I'm able to see 4 signals.I have consulted many ophthalmologist they doubted cataract or glaucoma but after checking everything was fine.they said one in a lakh people have this disorder. I'm diabetec for nearly 15 years and hypertension for past 3 years . doctor after testing my eyes they say that there is no traces of defect in the eye.I find it very difficult to drive my vehicle (2 Wheeler as well as 4 wheeler at night). what is the solution for this problem???.if I wear a contact lens will it be okay ???or need any eye correction..
