In astrology, the Sun rules the right eye and the Moon rules the left eye. Afflictions to them from Mars, Saturn, Neptune or Pluto
can indicate blindness or eye trouble. But the planets aren't the only indicators. What the astronomers call galaxies or star clusters
which look like fuzzy light to the naked eye, or even under a telescope, can also indicate eye trouble when in close aspect to your
Sun, Moon, Ascendant, and Mercury, or some other sensitive or personal factor in your chart. It is precisely this "fuzziness" or "haziness"
that obstructs the vision.
Below is a list of the most common starry objects associated with blindness or eye trouble. A one to two degree of orb is recommended, Conjunctions are of course the most significant, followed by oppositions and squares. The other aspects can have mild to unpredictable effects when within one degree of orb. The declination can strengthen or weaken the effect. Positions are given for the year 2000 AD and move at a rate of 1 degree or 60 minutes of arc every 72 years, or .8333 minutes per year.
