What does the term "oleophobic" mean in relation to lenses?

Visibility in low light conditions
Ability to filter UV light
Resistance to impact
Oil repelling

The correct answer is: Oil repelling

The term "oleophobic" in relation to lenses means that the lenses have the ability to repel oil. This is particularly useful as oils can cause smudges and reduce the clarity of vision through the lenses. By being oleophobic, the lenses are easier to clean and maintain, as they are less likely to attract and retain oils from fingerprints or other sources. The other options are not correct: - Visibility in low light conditions (A): This refers to lens tints or coatings that improve visibility in situations of low light, which is different from being oleophobic. - Ability to filter UV light (B): This pertains to the lens' capability to block or absorb ultraviolet rays, which is not related to being oleophobic. - Resistance to impact (C): This relates to the durability and ability of the lens to withstand external forces, rather than its oil-repelling properties.
