it means that your eye balls are bigger then normal at horizontally . it is not a disease, it is just bigger size of your eye balls although it is a beauty to have bigger eyes , but it posses less vision. you may get rid of glasses if you go for refractive surgery, lasik or femto lasic , Dr. Pricilla will also guide you soon.

Nice video, thank you. I'm nearly 50, my left eye sees "higher" than my right. When I was 10 my mum took me to a specialist where I was seeing two pictures, typically a bird and a cage, and I was told to train my eye muscles to "line up". For over 30 years I get laughed at every time I ask opticians why no one offers these exercises any more. Any advice? Thank you.

Thanks
When I put my contacts in my left contact feels as though its not there (comfortable). However, when I put my right contact in, it feels awkward like it is not setting correctly. I can almost feel the contact edges. Now with that said, I've doubled check to make sure the contact hasn't flipped inside / out. Bottom line is the right contact I can feel but the left contact is comfortable. Any explanation for this discomfort?

Hi, great video. But can you explain and tell me how what does N V/A 6/9 mean in decimal numbers?

@EyesExplained
3 жыл бұрын
I'm not sure if I understand your question. But the best way to determine if there are retinal problems is to have an eye test regularly. If you have new symptoms such as blurry vision, flashing lights or floaters in your vision etc then see your eye care provider earlier to investigate. I hope that helps.
Great video, very useful information. But doctor 1 question I had, I have had spectacles since many years now. In my recent eye test I noticed that my spherical number and cylindrical number is same but my axis changed from 70 to 180 degrees. So, this could be due to what circumstances? Thanking you in advance.
@notsuredc
2 жыл бұрын
i’m not a doctor but a student orthoptist. it’s good that you’re getting regular eye tests because everyone’s eyesight changes as time goes on. the increase in axis means that the front shape of your eye has changed. it’s nothing to worry about. your axis is now adjusted better!
My Dr. can't seem to get my Rx correct. I started with lined bifocals. Then changed out for progressives. The bifocal wasn't good for reading and distance was slightly blurry. The intermediate range of the distance viewing was good. The distance of the progressives is perfect. The bottom reading part is good but down too low in the lens to be useful. The intermediate view middle section is almost useless. I can make out the computer screen but can't read what I'm typing. She says I have a slight astigmatism. Does that create my problem with getting a proper fit? I'm spending a couple weeks wearing the progressives attempting to get "used" to them They make my eyes hurt. It looks hopeless for me.
I'm in my 60s, and my contact prescription just changed from -4.5 to -3.5. How long should it take to get adjusted to the new prescription? I tried to find information on the internet with no luck. Left eye lens is pretty good, but right eye lens seems to go in and out of focus (in focus 80% of the time). The prescription is fine as long as the lens is sitting in the right spot. Been a week. Should I give it a few more weeks or ask the dr to look into it now?
I wish my eye doc explained this to me. First time getting percription glasses, this is great information.

What if my sph says PL Nvm found it it means 0.00 yay your video gave me so much information thankyou !!!
Now I know why my cylinder and axis changed. In my exam 2 years ago, I strained my eyes to focus in on the figures better, and in my recent exam earlier this week, I made sure to avoid doing it because I naturally want to see the world with relaxed eyes. So that's why objects aren't out of focus (sphere unchanged), but I feel a little dizzy or off balance. Can't wait for my new glasses to arrive!

What does this mean? She told me I now have 20/20 vision. But the prescription says that my right eye is 20/20 -2. What does this mean? 6:40
Can Distance Vision portion of prescription has +2.0 for Sphere ?I thought it would always be negative number , is that right ? Question -IF THE SPHERE IS +1.5 AND THE ADD COLUMN IS +2.0. DOES MY SPHERE THEN BECOME +3.5=+1.5+2.0 like combination of two values . i want to buy just over the counter Reading Glass but not sure how to read eye prescription .Could you help. so like in the above example , am i suppose to get reading glass of +3.5 or just +2.0 ? Thanks
Thing with contacts is you can't get your exact prescription in them which is what I was told today when I went for my contact lenses eye test and the worst is my diameter is 14.00 but I can't find any that are 14.00 with the right base curve the ones I find with the correct diameter the base curve is 8.7 instead of 8.6 where I find the 8.6 the diameter ends up being 14.2
@EyesExplained
2 жыл бұрын
Your optometrist should be able to help you find the best fitting contact lens for you. The base curve and diameters are 'general guidelines' on how the fitting will be but it doesn't replace your optometrist assessing the lens on your eyes. We made a video about contact lens prescription which may be helpful for you kzread.info/dash/bejne/ZISspY-TZbXOj5M.html

Hi Dr thank you for the video. I recently got my glasses at my campus optometry clinic. I could not get my file details nor my prescription. The doctor i went to at first for the eye testing and fitting of my prescription was changed when i collected my glasses. My glases have these numbers: 52 □17- 140 C2. Can you reiterate what these numbers mean? I can't really see at a distance, especially my right eye. Whenever i take off my glasses the right eye becomes blurry and painful it even shrinks. The migraine headaches especially right eye hits very hard, whenever i try to relax because i can't wear my glasses while taking naps etc. My left is beter than my right even though i squint a lot to see properly we'll i try, its also mildly blurry. I've crammed my living space, whenever i got outside i have headaches when not wearing my glasses even if it can be 5minutes. Its hard to see people at a given distance. I have light sensitivity as well which makes it hard to walk in the sun without my transition glasses. I get dizzy when I've taken my glasses off. My left sees better but even with my computer or phone i see blurry without glasses?! 😊💛thanks Dr!!

The 52, 17, 140 C2 numbers is not your prescription. That is just the frame measurements and colour code. If you're having trouble with your glasses, return to the place you got them and they can troubleshoot to see what the problem is. Unfortunately I cannot give you any advice without knowing a lot more detail.

The axis can be in any number from 1 to 180. It just notes the direction of the curvature of your cornea. There isn't a 'normal'. And it is possible to have a combination of hyperopia, myopia and astigmatism between the two eyes. :)

You can get migraines with the aura or without. Sometimes people get the aura without the headache. You will need to find the trigger for your migraines. Sometimes if the prescription is incorrect it can be a migraine trigger. If your prescription is up to date then it should be unrelated to your eyes and glasses. Hope that helps!

Can your Cyl and Axis on one eye be zero one year, then in that same eye have numbers for both Cyl and Axis, then the next year both back to zero in the same eye? Also, can an inaccurate Cyl and Axis number cause blurriness and disorientation in your Ex?
@EyesExplained

Sometimes peoples' prescription can fluctuate by an 0.25. So possibly your cyl may be very minimal like an 0.25 and then one year it is 0. Having an inaccurate prescription may cause blurriness and disorientation.
