Which is more comfortable spex or lens?

You are right, it's one's choice. There are many differences between glasses and contact lenses, but there are some similarities, too like both require careful handling and cleaning. Glasses must be sprayed and wiped several times a day, while contacts need varying degrees of care, depending on the type. GP contact lenses are particularly fast and easy to clean. Both are affordable and when you consider that you wear glasses or contact lenses every single day of your life, the amount you spend on them is far less than for any other item in your wardrobe. Considering how important they are to the quality of your life, they're invaluable.
