Hello All, I want to warn all of you please NEVER to use halogen
lighting as your primary light source. The light emitted will cause
damage to the cornea with a condition known as Thygeson’s
Superficial Punctate Keratitus or SPK. It results in fine scattered
areas of loss of the epithelium (the outermost layer of the cornea)
from the cornea- the clear part of the surface of the eye. The
lesions appear punctate (looking like dots or points) but can
sometimes appear dendritic (linear and branching).
UV light is the most common cause of radiation injury to the eye,
such as over exposures to the sun or solar eclipses or exposures to
the sun on highly reflective snow fields at high elevation.
Artificial sources of UV radiation also cause corneal damage. Injury
from a welder’s arc commonly is known as flash burn, welder’s flash,
or arc eye. Other sources of UV radiation injury include suntanning
beds, carbon arcs, photographic flood lamps, lightning, electric
sparks, and as I mentioned, halogen desk lamps.
For years I have suffered with a burning sensation on my eye-balls,
like sand paper, painful light sensitivity (which I personally
believe triggered my cluster headaches), and tearing, to name a few
things. An opthamologist finally told me what was going on.
Fortunately, I have yet to experience any decrease in vision.
I hope my experience with this condition will alert other people to
the dangers of UV light. So, folks, please protect those beautiful
Regards to All, Mollie p.s.-thank you Orchid members for all the
incredible I have learned as a result of this forum!
