Best eyeglasses for old man!

[new eyeglasses]

I am planning to buy a new pair of prescription eyeglases, but you know that today's different patterns of fashionable eyeglasses are available in the market place that vary from animal prints to pretty plaids. You can get full-rim, half-rim and rimless styles in plastic, metal or even titanium materials, there are so many pleasing eyeglasses with graphic stripes, tortoise patterns and prints like buffalo horn. I am not interested in designer, fashion etc, what kind of eyeglasses do you think is the best for a 54 years old man?
