4.1.7 Flashcards
What can cause intolerance to wearing spectacles due to incorrect prescription?
Eye strain, headaches, or dizziness
If the prescription is too strong or too weak, it can lead to discomfort. Astigmatism corrections that are too high or incorrect can also make glasses feel uncomfortable.
What adaptation issues might someone face with a new prescription for glasses?
Time to adjust
Especially relevant for multifocal or progressive lenses. People switching from contact lenses to glasses may also struggle with peripheral vision changes.
What discomfort can poorly fitting frames cause?
Pressure on the nose, behind the ears, or temples
Heavy frames may also feel uncomfortable after prolonged wear.
What are some issues related to lens type and optical distortions?
Distortions at the edges for high-index lenses
Bifocals or progressives can feel unnatural if the transition zones aren’t well-placed.
Who might experience neurological sensitivity that affects wearing spectacles?
Individuals with migraines, vestibular issues, or sensory processing disorders
These individuals may be more sensitive to visual changes.
What is habitual avoidance in the context of wearing spectacles?
Resistance to adapting to glasses
If someone isn’t used to wearing specs, their brain may resist adapting, making glasses feel ‘wrong’ even if they are optically correct.
