I often hear, "You should never cheap out on a good office chair, shoes, underpants, backpack etc.." but what are some items that you would feel OK to cheap out on?
This can by anything from items such as: expensive clothing brands to general groceries.
Sunglasses. There's very little difference in terms of UV protection between cheap and expensive glasses and at the rate I scratch or break them it would be idiotic to spend a lot of money on them.
I need to object on the polarized lens. Polarized lenses are great if you are spending all your time outdoors and never get in vehicles or need to look at electronic displays, but most vehicles and displays have a polarizing filters. Mixing two polarized lenses together is not a great idea as it can lead to blind spots.
I drive trucks for a living and can’t use polarized glasses for that reason. I’ve heard pilots are in the same boat. Having blind spots when you are herding that much mass is a bad idea.
I learned early that there is a direct relation from how much I spend to how long I will keep them without breaking them, loosing them, or somehow destroying them in creative ways. I have a 10€ pair that has, so far, has lasted 2 years.
