  • We don't just dilate your eyes for our own sadistic pleasures. This is why we do it.

    Dr. Sparhawk!
    I love your videos! I was so sad when you stopped uploading. Could you possibly do a video further explaining "diopters" and how prescriptions for lenses work?
    Thanks!

    good question. I usually use 1 drop. for some people two drops (which are complimentary) are used. If there is need to keep the pupil dilated for an extended period there is a type that will leave the pupil open for 24 hours.

    What about pupil dilation and light sensitivity after the use of acid (and by acid, I mean a miscellaneous psychoactive/psychedelic substance active in the micro-gram dose). The light sensitivity is of moderate insensitivity, and can become painful when looking at a computer screen specifically. This problem didn't exist before taking two tabs of acid, and does now even up to two weeks after- though periodically. Pain is reduced slightly via taking off glasses, but persists after its started. Upon examining eyes, pupils are dilated during these periods.
    Could this be due to scratches on the glasses causing light sensitivity, some sort of dietary issue effecting eye health (e.g. nutrient deficiency), or could this be directly related to other acid (i.e. if it was 'fake acid' like a research chemical, such as NBOMe, that caused some sort of physical alteration with the pupil dilation mechanism)?
    Is there a safe way of making the pupil contract (e.g. specialized eye drops) to reduce the pain from light sensitivity, or is this something that should be examined by a professional?

    I've had my pupils dilated many times by my glaucoma doctor. It's harder to dilate my eyes because they're really small and my left eye is the worst eye. So far my eye pressures have
    been good because of my eye drops. I've also had the applanation tonometry many times by my glaucoma doctor for 15 years.

    i've had Photophobia all my life as well as a few other conditions. I can't go out in regular weather without wearing sunglass which I hate. If I dilute my eyes can that help with the situation? Or will it make it worse?
    I've seen some video on how to dilute them yourself at will.

    How many drops do you put? My Mother had an eye exam and it took her nearly 5 hours for it to dialate HALF of its normal size

  • @justinsparhawk
    @justinsparhawk  11 лет назад

    There are several. The one I use most is called Tropicamide. Another common one is Phelylepherine. Yet another, used for the big long lasting dilation is Cycopenolate. They all work in different ways.

  • @bookreader902
    @bookreader902 13 лет назад

    Why does dialting the eyes hurt so much, literally feel like your eye is on fire when the dialating drops are put in, even though they put the numbing drops in first? It always happens, the numbing drops dont work, and i end up feeling this searing pain.

    i got it that it is important to dilate pupil for fundus examination but why doctors dilate pupil for retinoscopy and give two readings i.e. retinoscopy with dilation and they call once more after a week for giving a confirm power of glasses.how dilated pupil helps to determine the power of glasses?

  • @edkollin
    @edkollin 9 лет назад

    Did it yesterday. Six to 8 hours before pupil started going down. It was like you turned on your monitor full brightness, just this bright milky haze. Being under a blanket and still too bright was strange. It was still like that this morning. The rest of the day eye felt tired and sensitive. Usually I could adjust from going from the inside to outside into the sun in like 10 seconds. Today took 1/2 hour. I felt worn out from the whole exam today, like you feel when you have exercised muscles for the first time in a long time.

    i went to the eye doctor today and got my eyes dilated. he put the drops over my eye lashes, so i didnt even have to open my eye. after he looked at my eye, he asked if i ever had an infection in my left eye. And then he said i have a scratch on my eye, but it doesnt have any effect over my vision. what is the scratch? is there any way to fix it?

    @leahcimrac For some people who might not know, Photophobia is sensitivity to light. Dilating the eyes like we do for the exam actually makes the eyes much MORE sensitive to light for those couple hours that they are dilated. For some reasons, some known and some unknown, there are people who are more photophobic than others. Unfortunately, in most cases the only thing to do is just what you are doing, sunglasses and a hat.

    I honestly never realized this or spoke to anyone about this but I can dialate and constrict my pupils at will. I realized this while swimming, I can see a lot better under water when I dilate my pupils and in the dark. Hence my RUclips search found your video. Since I have no knowledge about this associated with other human's, May I ask, have you ever heard of this

  • @justinsparhawk
    @justinsparhawk  11 лет назад

    Some times three drops is used. The first is to measure the pressure of the eyes. The following two for the dilation. I typically use just one drop for the dilation but in some eyes two is needed. Some Drs automatically just put two in for every one.

    @arshinov20 10 лет назад +1

    To me it's the zoom in & zoom out of human eye 😄 that lense is just trying to focus. If you think i'm lying look at your phone for long minutes, close your eyes & open them again you'll feel the same thing that you see on the screen of your digital camera...

  • @justinsparhawk
    @justinsparhawk  11 лет назад +1

    Nope. I know that for the most part, dilation and constriction is involuntary. But I know some people can train mostly involuntary actions so I wouldn't rule it out or be surprised if some one could do it.

  • @TheLoneWolfer
    @TheLoneWolfer 13 лет назад +1

    I'm wondering, what about the drops makes your pupils dilate? I mean isn't it supposed to be light that makes it go big and small. Then how can a few drops of solution make it even bigger than any kind of light or lack of light could. I'm always wondering how big your pupils could get in total darkness, probably never know because you'd have to turn on some kind of light to check. lol jk.

      if a doctor ask to dilate your pupiles, pls avoid, it ruins your eye sight for about a couple of days, and if your in school, its like hell trying to see the board
