Winter in the north of Sweden can be difficult, with fewer than 5 hours of daylight for months on end.

So much so that in most workplaces, anyone who does not participate is deemed disrespectful. Perhaps this is why Swedish employees rank fourth in the world in terms of happiness!

The vision of each person is boosted as much as possible thanks to this personalised lens.

There are actually various varieties of cataracts, which is an intriguing fact that many people are unaware of. People are affected by the three basic categories in various ways. They are: Nuclear cataracts, which primarily develop in the lens's middle. The majority of cataracts in people over 40 are these.

This may sound like good news, but it has resulted in one major issue: there isn't enough rubbish to keep the incinerators going. As a result, Sweden has devised an innovative solution. To keep the lights on, they import garbage from Norway and the United Kingdom. As an added plus, the nations actually pay Sweden to remove their rubbish!
