Lately I've been having a bright light shoot through my left eye, I lose vision for that split second. What could this be?

Detached retina: 'flashes of light' with vision loss may be a sign of detached or 'detaching' retina which is an emergency. The retina is located at the back of the eye and is important for normal vision.
Detached retina can be painless and progress to vision loss--so it is best to get seen by an ophthomologist right away. ...Read more

I have a half circle bright light very colorful around my left eye and a slight headache on the left top of my head, what could this mean?

Migraine: Sounds like you are experiencing a classic migraine. The colorful image, which generally shimmers and changes in size, is an aura. The headache follows the aura. Usually lasts up to 24 hrs, but generally much less. If this a brand new experience for you, you may want your primary care doctor know about this. If your vision has been affected, see an eye md. ...Read more

Seeing reflection of: Blood vessels in the retina. Those lines are a reverse image (shadows) of what is in your eyeball, and you are seeing it at some jagged edges, when in reality, it's a vascular tree of your blood vessels in your eye, and quite normal. A bright light can be ocular migraine or can be phosphenes when you touch your eye and see a temporary light internally. This is benign in any case. ...Read more

Probably floater: Your description sounds like a vitreous floater. As long as your visual acuity is not altered, I would recommend scheduling a routine eye examination. However, if your vision has been affected or if you have associated flashes, obscuration of vision, distortion, pain, double vision, then seek immediate eye examination appointment. Generally floaters are a normal development with aging. ...Read more

I see a small bright spot in the same place in my left eye off and on for last 3 days. What is it and when should I get it checked?

Check soon: It's difficult to say what this is without more information. This could be part of the normal aging of the vitreous gel in the eye and it could also be migraine visual phenomenon. Since other more serious problems are possible it makes sense to see an eye MD if problem persists. ...Read more

Migraine?: I suspect a migraine aura which you could see at night or any other time. If you've never experienced this symptom before, make an appointment to see an eye md to reassure your eyes are okay. If you have other symptoms such as headache, nausea, & vomiting, medications may be prescribed if particularly frequent and severe. Usually tees events are stress related. May also have other triggers (food) ...Read more

Left eye has had hard time adjusting from light to dark- example after using bright phone in dark room, when turning it off eye has hard time seeing in dark for 10 minutes only left one, concerning?

Interesting: While it might be a function of your complicated medical history/situation, it is wise to see an eye dr for a dilated (/fundoscopic) examination and thorough evaluation to be sure there is not a direct issue with your eye or visual system. Some folks do take time to adjust, and some times a dominant eye is much quicker, but get checked to be sure. ...Read more

Left eye only has been inexplicably bright red all morning. No allergies, itchiness, or pain. Why might this be happening?

Iritis-Episcleritis?: Unilateral redness of the eye with no other symptoms could be as benign as a displaced eyelash or a subconjunctival hemorrhage versus as severe as iritis or other inflammation. Only an examination of your eye under the bio-microscope (slit-lamp) will provide a definitive answer. Visit an eye care provider. Myotonic dystrophy I is associated with the christmas tree cataract. ...Read more

For the past year I keep getting a hemorrhage in my left eye every 3 to 4 months. Most of the eye turns bright red. No pain. Possible causes?

? location of hemorrh: You may have experienced subconjunctival hemorrhage which is visible to the naked eye and is located on the white part of the eye (called sclera). This is a relatively harmless condition. Sometimes it is related to high BP. So I would advise you to first get your PCP to check your eyes and he will likely check your BP also.
This should be the first step. He may send you to a Eye specialist, if need ...Read more
