To wear eyeglasses or contact lenses? - apart from correcting astigmatism, I still want to look young as I am.

Go for whichever you are comfortable wearing. I do wear glasses because I feel more comfortable in it than using contact lenses. Also, I had difficulties when I used contact lenses before like I always need to put eyedrops so as to feel comfortable. I also worked for more than 8 hours a day in my previous work and wearing contact lenses for more than 8 hours really caused eye strain. Though, it is different for everybody. Some are masters in wearing contact lenses and some aren't (like me).
