You wear goggles under several circumstances: during blizzards to protect your eyes from the cold, and when spending long hours in the sun with its reflection off the ice, which can lead to snow blindness.
You would need to wear sunglasses when in the polar regions because the light is too bright. The occasional sunlight that passes through gets reflected off the ice. Since it is so white, it reflects it easily. If you stare at the ice too long you can become temporarily blind or even permanently blind.
In addition, because there is no particulate in the air, the sun is very bright. Also, because of the hole in the Ozone Layer, the sun's rays that reach the continent are extremely intense and can cause damage to your eyeballs.
Sunscreen is not sufficient protection under the hole in the Ozone layer in Antarctica. It is crucial to protect your skin from any sun exposure there by covering it up as much as is practical given your outdoor tasks.
Sunscreen will help minimize the UV rays that hit your skin, so it's a good idea to use it liberally on exposed areas.
During the period when most temporary scientists and workers are in Antarctica, the sun is up 24/7. This is generally between October to February. The hole in the ozone layer, coupled with the reflective nature of the ice requires that people wear sunglasses. As well, best practices dictate that all skin is covered, to avoid sunburn.

Sun protection factor. It is a measure of how much longer you can stay in the sun, without burning, when compared to not wearing sunscreen.
The SPF number on a sunscreen label stands for Sun Protection Factor. This means if the SPF is 30, this means you can stay in the sun 30 times longer than you would be able to without wearing sunscreen.
Wearing a chemical- or physical-based sunscreen may help prevent the sun's rays from causing photoaging and skin cancer. It may still be possible to get a slight tan, even if you do wear sunscreen. However, no amount of deliberate tanning is considered safe. Best sunscreen
