I have been a far sighted for a long time and I wanted to wear already sunglasses but when I tried once it is just a disturbance. I don’t know since I’m just use to it. Until I discovered using contact lenses. At first it has a difficulty of putting into it but later on I strive my best to put into it. I also find it very useful in my work and in everyday. Sometimes I got the nerve to use brown or gray lenses, who cares anyway LOL!
