Weird That’s weird Have fun trying to fix it
Answer:
D. Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
Explanation:
The eye disorder that makes people virtually unable to see in moderately bright light is called photophobia. Ocular photophobia, sensitivity or intolerance to light may be due to various eye diseases, or may result only from a greater "impression" or "irritation" with light by certain people, being more common in individuals of clear eyes.
Severe photophobia rarely manifests in normal eyes if there is no underlying disease. In rare cases people with enlarged pupils (large pupils) may experience greater sensitivity to light, as the larger the pupil the more light will reach the retina. However, wearing glasses that are transparent to red light components, but which filter out other light components, can help these people see with moderately bright light.
