What do you call the sunglasses that you get after getting your eyes dilated at the eye doctor?

What do you call the sunglasses that you get after getting your eyes dilated at the eye doctor?

"Post-mydriatic": Mydriasis is pupillary dilation and without pupillary constriction, bright lights can dazzle you or even cause a temporary bleaching of the retina. Pharmacologic dilation for diagnostic testing and examination can last 3 or more hours, depending on the drops used and the color of your eyes, with lighter colors lasting longer. The near vision is typically more impaired than the distance. ...Read more

Why won't my eyes un-dilate after being at the eye doctor?

How long should my eyes stay dilated after a visit with an eye doctor? I think they use too much medicine.

It depends: It depends on what eye drops are used to dilate your eyes. Some dilating drops last only around 3 hours, another may last 6 hours, another may last 2 to 4 days and another may last up to 2 weeks. The 2 to 4 day and the 2 week drops are used for treatment as opposed to examining an eye. Also, some eyes tend to be more sensitive to dilating drops and the effect tends to last longer in such patients. ...Read more

My eye doctor doesn't dilate my eyes during an eye exam, shouldn't they?

My eye doctor doesn't dilate my eyes during an eye exam, shouldn't they?

Yes they should!: Dilation of the eyes is part of a complete eye examination. The examiner cannot see the entire retina without dilating the eyes and it makes looking at certain parts of the such as the macula and optic nerve much easier after dilating. If you are seeing the doctor for a specific problem not involving the retina, you will not necessarily need dilation. ...Read more

Hi Doctors, Yesterday I went to an eye doctor and he dilated my eyes at 8pm it's now the next day 4pm and my eyes are still dilated! Why? I'm worried

I had blurred vision from my left eye. I went to the eye doctor (dilated pupils) and everything is healthy. It has happened twice. Can this be ms?

Yes.: You could go to a neuro-ophthalmology specialist. Another option that may be more available would be to see a general ophthalmologist. Regardless, the diagnosis of ms (multiple sclerosis) is based upon a variety of factors. It is not uncommon for it to take some time to make the diagnosis. Many patients are monitored for ms but never develop full blown disease. ...Read more

Can sunglasses be bad for my eyes? Is it better to have darker-colored lenses or higher uv protection (or both)? I heard that darker sunglasses cause the pupil to dilate more, which makes your eyes more vulnerable to uv rays. Is this true? Should I get li

Can sunglasses be bad for my eyes? Is it better to have darker-colored lenses or higher uv protection (or both)? I heard that darker sunglasses cause the pupil to dilate more, which makes your eyes more vulnerable to uv rays. Is this true? Should I get li

Ultraviolet: Ultraviolet (uv) light is harmful to the eyes, especially large amounts over long periods of time. In the United States, all sunglasses are required to block a very large percentage of the uv rays. The darkness of the sunglasses does not affect the uv filtering ability, since uv light is invisible and the uv blockers are clear. It is true that darker the sunglasses will open the pupil more and thus let in more uv light, but since almost all of it is being filtered by the sunglasses, this is not something to worry about. The exception would be specific eye diseases such as retinitis pigmentosa, in which extra high uv protection is a good idea. ...Read more

My eyes hurt a lot in bright places even inside and told the doctor that sunglasses really helped and then he didn't approve what should I do?

Light sensitivity: Can be very individual. I am not sure why the doctor did not approve of sunglasses. Preventing eye discomfort by wearing sunglasses seems like a simple and safe intervention.

My contact perscription from eye doctor was a -2.00 in both eyes. Is that strong? When is someone considered legally blind?

My contact perscription from eye doctor was a -2.00 in both eyes. Is that strong? When is someone considered legally blind?

No: -2.00 would be considered a low amount of nearsightedness. Legal blindness does not have anything to do with the magnitude of your prescription. It has to do with how good your vision is while wearing your correction. Definitions vary by state but generally vision of 20/200 or worse with the better seeing eye is the criteria. At -2.00 your vision would be better than that even without correction. ...Read more

Can you tell me if an eye doctor checks your eyes and says they are perfectly healthy, what can cause floaters in your vision?

Commonly floaters: Are from the loss of clarity of the gel-like substance inside your eye (vitreous). This is a natural process in most patients and does not require treatment. Your doctor was checking for retinal tears or retinal detachments that can sometimes be associated with new floaters. Retinal issues would require treatment. Be well. ...Read more
