hi...my name is AAAAAAA and I am 26 yrs old...three months ago I had a vision test, I came to know that my right eye have a power of -0.25, I thought to use contact lens without any perscription but after using contact lens ( for around one hour), cloudy vision and rainbow halos are seen around the lights, after that I stop the use of contact lenses . After that I went to an ophthalmogist he checked my eye refractive index it was ok and he prescribe me an eye drop of carboxymethyl cellulose sodium salt .5 %w/v and ask me to take vitamina a capsule but still I am facing the same problem. Symptoms are rainbow halos and cloudy apperance, redness in eye ( Right eye ). Kindly suggest me some precautions and medicine so I can protect my eye vision. Regards Rajiv
