i used to wear contact lens everyday...my spec is only for at night at home (that spec i used it for like so many years and the power is too low) but i dont bother to change coz i think its just for few hrs at home before i go to bed...

recently went to check my eyes and power increased...bought new pair of specs...but hardly wear..only use it at home..now after few mths i realised the spec is not clear...

does this mean my power had increased again??

many people saying that dont use colour contact lens. is it true that its not good especially those korean type one?
