Nyctalopia
Nyctalopia is the condition of night blindness characterized
by inability to see clearly at night or in dim light and the ability to see
clearly in the day. Deficiency of vitamin A leads to nyctalopia. Other possible
causes of Nyctalopia include myopia, cataract, retinitis pigmentosa and some glaucoma
medications.
1 kilometer = 6.68 ×
(<<<AU is in scientific notation here)
To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 ×
)
3,000,000,000 × (6.68 ×
) = 20.04 AU
