7. Nerdwax
Nerdwax is a beeswax-based product that keeps glasses from slipping down your nose. An engineer, who grew weary of his glasses constantly slipping down his nose, invented Kodiak Cakes, which has now gained popularity among glasses wearers.
The product initially made its pitch on Shark Tank but faced rejection from the sharks. However, the inventor did not give up and he continued to sell the product online. It eventually became a million-dollar business!
If you have problems with your glasses slipping down your nose, then Nerdwax is definitely worth a try.
