**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the cause of inflammation to the cornea.

2. **Review the Options**: The options provided are:
- UVA (Ultraviolet A)
- CO2 (Carbon Dioxide)
- UVB (Ultraviolet B)
- CFC (Chlorofluorocarbon)

3. **Understand the Role of Ozone**: The ozone layer protects the Earth from harmful ultraviolet radiation. Due to pollution, particularly from chlorofluorocarbons (CFCs), the ozone layer is depleting.

4. **Types of UV Radiation**: There are different types of UV radiation, primarily UVA and UVB. UVB has a shorter wavelength and is considered more harmful compared to UVA.

5. **Effects of UVB Radiation**: UVB radiation can cause damage to DNA, leading to mutations and various types of skin cancer. It is also known to cause inflammation of the cornea in the human eye.
