Day blindness or Hemeralopia is a symptom in which vision is impaired in daytime (photonic conditions), whereas night vision (scotopic conditions) is preserved.
Etiology of Day Blindness or Hemeralopia:
The visual system consists of two components that are relatively independent of one another; The sensory organ, the eye (image sensor or camera – The retina and optic nerve – the transmission path) and parts of the central nervous system.
The retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species to “build a representation” of the surrounding environment.
The neuropsychological side of visual information processing is known as visual perception, an abnormality of which is called visual impairment, and a complete absence of which is called blindness. Non-image forming visual functions, independent of visual perception, include (among others) the pupillary light reflex and circadian photoentrainment.
Humans are blind for about 40 minutes per day because of Saccadic masking—the body’s way of reducing motion blur as objects and eyes move. 20/20 isn’t perfect vision, it’s actually normal vision—it means you can see what an average person sees from 20 feet.
Symptoms of Day Blindness or Hemeralopia
- Inability to see clearly in bright light
- Eye discomfort (Photophobia)
- Pain in light
- Inflammation of eye
Main causes of blindness
- Cone dystrophy (6-7 million, located in central portion of retina called
“Fovea”, responsible for photonic vision (bright-light vision)
and color perception, can resolve fine details), - Achromatopsia (partial or total absence of color vision),
- Aniridia (abnormal development of the iris of the eye),
- Albinism (Albinism affects the production of melanin, the pigment that colors skin, hair and eyes),
- Cataract,
- Genetic mutation at locus 8q22-23 chromosome.
Allopathic Treatment for Day Blindness or Hemeralopia
In allopathy there is not any treatment for day blindness or hemeralopia except surgeries in some cases, but surgeries never give good results; just waste of time, of too much money and collect lot of toxins inside patient’s body especially liver (drugs side effects).
