While polarized sunglasses are extremely popular for their anti-glare feature,
pilots should avoid using these because their coating will make it almost impossible to read the digital instruments inside the aircraft.(A) pilots should avoid using

Wrong. "these" is wrong. The correct pronoun is

TO do something." is correct. "make it impossible
doing something" is wrong.

Correct. Hope it helps.
