Hi, I want to ask if I can wear ordinary sunglasses (let's say from the Vietnamese) when I wear contact lenses. The opticians told me that if I had lenses, I would have to buy sunglasses for about CZK 2,000. But I know a few people who wear lenses and don't have god knows how expensive glasses are. So I want to ask what it's like if anyone has experience with it. Thank you in advance for your reply.
