I am near sighted and wear glasses or contacts throughout the day and can see fine. I sometimes get really irritated eyes from my contacts but, other than that, have no major vision problems. I use eye drop regurally, both when I'm wearing my contacts and when they are out.
However, I have been getting very blurry vision at night. Not just with seeing far away, but also with reading (I can normally read just fine without even having to wear my glasses). When I say blurry I mean it is quite bad; I really can't concentrate on what I am reading and definately would not feel safe driving like this. I basically have to squint to even make out anything I am trying to see.
This only happens on some nights, which is what I find odd. I has happened the past 2 nights and I have not worn my contacts since 3 days ago, so I don't think they are what's causing the problem. This normally starts to happen around 10 at night and just gets worse as the night goes on. It is normally completely gone (or significantly better) in the morning. Any ideas of what this could be and how I could fix it?
There are several causes for this, all of them need medical attention pronto. It's not just the black spot (serious enough in itself) it's the "photosensitivity" symptom that's worrying. This will manifest itself during the daylight too if there is bright sunshine. Your eye will be unable to deal with bright sun and high contrast situations. This is already making your night driving unsafe. Until you're sorted out please don't drive in the dark. An accident will cause more damage than it's worth, and you may also get into trouble for driving with an eye problem. I understand that you're worried sick about seeing an optician just in case they say there's something horrible wrong; but that is exactly why you must get medical attention. If there is a problem then it can be treated, if it's "nothing to worry about" then you can stop worrying. Your eyes do not re-grow and they're bad at self maintenance and repairs. Diseases and other faults tend to get worse if not treated, until the eye fails completely, then it's too late. In other words, when you're offered an appointment do not negotiate because of work or family things - take the first that you can get.I'm not being sensationalist; nor am I trying to tell you exactly what's wrong - only an eye specialist can do that. That is why you must call your surgery now and make that appointment. If the GP can't see you within a few days then take yourself to the eye casualty department of your local general hospital (most have one, or something similar) to see a specialist. They're very good at dealing with "drop in" patients. Be prepared for a wait of many hours but do not give up (how ever much the parking fee turns out to be).
