The nystagmus becomes less noticeable with age but the other symptoms of the syndrome become more relevant as school age approaches. Visual acuity and stability of the eye motions generally improve during the first six to seven years of life – but remain near 20/200. Otherwise the syndrome is considered stationary and does not worsen with age.
Blue cone monochromacy (BCM), also known as S-cone monochromacy, is an X-linked cone disease. [5] It is a rare congenital stationary cone dysfunction syndrome, affecting less than 1 in 100,000 individuals, and is characterized by the absence of L- and M-cone function. [ 6 ]
Visual snow syndrome is often linked to heightened neural sensitivity in the visual system and may require diagnosis and treatment, as it could be associated with underlying eye conditions or neurological disorders. [citation needed] In summary: Visual snow as a temporary occurrence under certain conditions is normal and doesn't require ...
More specifically, the L cone absorbs around 560 nm, the M cone absorbs near 530 nm, and the S cone absorbs near 420 nm. [1] These cones transduce the absorbed light into electrical information to be relayed through other cells along the phototransduction pathway, before reaching the visual cortex in the brain. [1] The signals from the 3 cones ...
S Cones are most sensitive to light at wavelengths around 420 nm. At moderate to bright light levels where the cones function, the eye is more sensitive to yellowish-green light than other colors because this stimulates the two most common (M and L) of the three kinds of cones almost equally.
Normal human color vision is trichromatic, so dichromacy is achieved by losing functionality of one of the three cone cells. The classification of human dichromacy depends on which cone is missing: Protanopia is a severe form of red-green color blindness, in which the L-cone

Blue cone monochromacy (BCM) is an inherited eye disease that causes severe color blindness, poor visual acuity, nystagmus, hemeralopia, and photophobia due to the absence of functional red (L) and green (M) cone photoreceptor cells in the retina.
