Flashes of light or eye floaters that move across your vision.This sight-threatening condition generally results in a sudden onset of blurred vision, along with: Retinal detachment is an eye emergency that occurs when the retina is pulled away from its normal position on the back wall of the eye. Numbness or tingling in extremities, especially on one side.Difficulty speaking or understanding speech. Seek immediate medical attention if you are experiencing any of the following symptoms along with blurry vision: Strokeīlurry vision in one or both eyes can occur when a stroke affects the visual areas of the brain. Here are six emergencies that can cause blurry vision in one eye: 1. While blurry vision is often associated with a need for eyeglasses or a new optical prescription, monocular blurry vision can signal a more serious condition that requires immediate attention.īlurry vision that comes on suddenly or appears only in one eye can be a sign of a medical emergency and should be evaluated immediately by an eye doctor or another medical professional. By far the simplest explanation for these last two is that they are Jupiter-mass objects at Solar-System-like distances.Are you experiencing blurry vision in just one eye? This could be a sign of a serious eye condition. The Doppler velocities of 16 Cygni B have the clear signature of an oval orbit, precisely consistent (and predictable) from newtonian physics. Further, the planet discovered around 47 Ursae Majoris 8 seems quite ‘normal’, having a minimum mass of 2.5 Jupiter masses and orbiting at 2.1 Earth-Sun distances in a nearly circular orbit. Their number and variety provide a powerful argument against quirky explanations for any individual detection. But all of the above threats to the planet interpretation lose strength in the face of the seven additional planetary companions since discovered around other stars (see Table 1). Instead, we can tell that the star rotates roughly once every 30 days, based on its weak magnetic field - not much different from that of the Sun. For example, the brown dwarf would raise tides on the primary star, and so exert a torque that would spin-up 51 Peg to a 4-day rotation period. But some of them can be rejected by astrophysical reasoning. This plethora of interpretations represents science at its healthiest. The empirical case for oscillations has vanished, leaving planets as the only plausible interpretation. But now, three papers 3, 4, 5 (including those on page 153 and page 154 of this issue) report that the spectral evidence of pulsations is absent, after all. This interpretation called into question the reality of not just the 51 Peg planet, but also the other five detected extrasolar planets, as highlighted by the cover of Nature (27 February 1997): “Extrasolar planets: Fading from view”. But criticism of this interpretation came from David Gray 2, who reported spectral-line variations that could be caused only by an undulating, pulsating stellar surface, not an orbiting planet. The original suggestion 1 that a planet exists around the star 51 Pegasi was based on periodic variations in Doppler shifts of the light from the star - presumably caused by wobbling because of the gravitational pull of the planet. Last year a conflagration of controversy engulfed the first planet ever claimed around a Sun-like star now it has suddenly been extinguished, leaving the new world unscathed.
