Ask an Eye Doctor and Get an Answer ASAP
Hi. I'm online and happy to answer your question today.
How heavy do you think the weight is? Does the weight press directly on your eyeball without touching the bones around your eyes?
Hi Dr. Rick
I am manufacturing sleep masks and the weight is about 3 ounces -weight is distributed over the eye ball and bones around the eye
3 oz is a lot of weight when it comes to pressing directly on the eye. This weight would be expected to cause an initial increase in the intraocular pressure and, after about 10 minutes, a decrease in pressure as the aqueous fluid was forced out of the globe. It would be best if the weight was supported primarily by the orbital bones.
My cusomter reported blurry vision??What do you think?
I was just gonna say that this would cause blurry vision...
It could also cause damage to the optic nerve in patients susceptible to increases in eye pressure, such as those with glaucoma, decreased ocular blood flow etc.
weight is distributed, however elastric strap may cause pressure by being too tight?
It sure could. In some patients, prior to cataract surgery, a device (honan balloon) is used to press on the eye and soften it to make the cataract surgery safer. What your mask is doing is right along the same lines....but in an uncontrolled fashion for a possibly extended period of time....
Is it possible to redesign it so that the eyes do not have any weight on them?
Or only a very small amount of weight, say like an eye patch would have?
How would you suggest we warn our customers of the possible effects-We have sold several thousand of these eye pillows without reports or blurry vision
It is always difficult to warn people since 1. They may panic 2. There are too many starving lawyers running around loose 3. and only a small number of people may really be affected.
i am trying to help people sleep and not hurt them
Perhaps warning about over use as with other medications etc?
We can make them lighter
I guess if you have contact information for your customer base you could get try to put together an informational flier/email....this gets into marketing/liability and I am just a simple country retina specialist......
lighter would be good or, better yet, change them so that the weight is supported by the nose/forehead/orbital bones with, perhaps, fabric soothing the eyelids.....
What would be the worst thing that would happen if somebody used these every night?
Worst thing in someone with an already severely damaged optic nerve, say a patient with advanced glaucoma who can not tolerate increases in ocular pressure? Lights out blindness. (You asked for the worst :)
Is this likely? Not really. But then people win the lottery every day....
