Hearing Loss And Visual Impairment:

1.

The three barriers to care for visual impairment are: •Inability to see properly and visually sense surroundings - i.e. putting toothpaste on toothbrush. •Visual cues that would raise concern go undetected – i.e. caries, cancerous lesions. •Difficulty understanding and grasping oral hygiene instruction – i.e. cannot visually see the educators demonstrations.

A.

True
B.

False

Correct Answer
A. True

Explanation
The given statement is true because it accurately describes the three barriers to care for visual impairment. These barriers include the inability to see properly and visually sense surroundings, which can make simple tasks like putting toothpaste on a toothbrush difficult. Additionally, visual cues that would raise concern, such as caries or cancerous lesions, may go undetected. Finally, individuals with visual impairment may have difficulty understanding and grasping oral hygiene instruction if they cannot visually see the educator's demonstrations.
