I have been using varifocal lenses for the last couple of weeks, I am long sighted generally but as i've aged (44 years old now) I now need distance glasses too. The optician was dubious when I said I wanted to try them but was shocked when I took to them immediately. I have to go back this Thursday for a check up to see if I want to continue with them. I will be keeping them but will also be ordering a new pair of reading glasses for the times when my lenses are uncomfortable/annoying me.
