If you were to open your eyes underwater, could the water damage the surface of the eyes like the cornea, conjunctiva and the sclera?

No: While the eyes might become irritated and be somewhat red when you surface, the water if uncontaminated, will cause no surface damage. Salt water in fact would be less harmful since it matches the surface fluids of the eye more exactly. ...Read more

I have heard, is it true that lubricated tear drops heal the irregular, scarred and swollen corneas? Will it also cure the conjunctiva membrane?

Depends!: Lubricating drops help to smooth the surface of the cornea, but there is only so much they can do.

Conjunctival membranes are from a variety of sources! And they are neither common, nor regular!

you best follow the advice of your ophthalmologist (not optometrist). ...Read more

How do you quickly heal and cover a black eye?

I went for a vision field test and I think I was supposed to cover one with an eye patch to see the flashing light but I didn't? Is this a problem

I went for a vision field test and I think I was supposed to cover one with an eye patch to see the flashing light but I didn't? Is this a problem

Incorrect test: Visual field testing is done one eye at a time. The fields of each eye overlap and doing it with both eyes will combine the input from each eye. If you had the test this way, the result will be largely meaningless. Did you have this done by an optometrist? Or did you see a real doctor - an ophthalmologist.? ...Read more

I had to cover my eye for a couple of hours and now that eye can see in the dark perfectly, while the other one just sees the dark Like it's supposed to. Like its all lit up? Is that normal or am I just a mutant?

I had to cover my eye for a couple of hours and now that eye can see in the dark perfectly, while the other one just sees the dark Like it's supposed to. Like its all lit up? Is that normal or am I just a mutant?

Totally normal: And temporary. Eyes adjust to light level at many levels. The size of the pupils (which does NOT differ between the two eyes), the pigments in the eye wear out with light/use. The nerves become more or less sensitized and even brain cells adjust. ...Read more

Why do optometrists make you use those spoons to cover one eye?

Why do optometrists make you use those spoons to cover one eye?

To check vision: The "spoon" or occluder allows an eye doctor to test the vision of each eye individually. An individual assessment of the vision of each eye is necessary to determine if there is a loss of vision and from which eye. ...Read more

Can wearing an eye patch on a "good" eye cause vision damage, or make the covered eye lazy?

Amblyopia: The treatment for a lazy (amblyopic) eye is to patch the good eye in a controlled manner. Sometimes the amblyopia can switch but the vision is recoverable. That is why it needs to be done in a controlled manner. ...Read more

Use progressive lenses and monovision contacts. When I cover one eye objects appear larger in one eye than the other. Why is that?

Use progressive lenses and monovision contacts. When I cover one eye objects appear larger in one eye than the other. Why is that?

Accidental telescope: The eye with the more minus contact lens sees the larger image because a minus lens acts as an eyepiece in a Galilean telescope, while the progressive bifocals act as the objective lens. This is of theoretical, but little practical value clinically. Either switch to bifocal contact lenses or correct both eyes for distance with the lenses and use over-the counter readers. Aniseikonia fixed. ...Read more

I am experiencing a bluriness in my vision. When I cover my right eye and blink, I see a black circle with white border and black outline.

I am experiencing a bluriness in my vision. When I cover my right eye and blink, I see a black circle with white border and black outline.

Exam: Some possible causes of your blurred vision include abnormalities such as nearsightedness, farsightedness, presbyopia, or astigmatism which can be improved with corrective lenses (eyeglasses) or this may signal the presence of eye disease or another illness. I strongly encourage you to see an Ophthalmologist (Eye Dr Specialist). In the meantime please go to a clinic for a general medical exam! ...Read more

Can I get the vision in my left eye up to par with my right eye by keeping my right eye covered with a patch, forcing my left eye to do more work?

Can I get the vision in my left eye up to par with my right eye by keeping my right eye covered with a patch, forcing my left eye to do more work?

Patching: Patching the better visioned eye does improve visual acuity in children particularly when they are 9 yo or less in age. Even to some degree patching up to 17 yo can help, but less effective. I didn't get your age, but if you are an adult, the benefits of patching will not likely have a positive impact. You should see an Eye MD if you are concerned about your vision. All you may need is glasses. ...Read more

Have been seeing a slight dual vision. For example I have dual vision when right eye is covered and I have dual vision even if the left eye is covered?

Need ophthalmologist: You should get a good OPHTHALMOLOGICAL checkup. What you're describing can happen in several situations but the ones you really want to get on top of quickly are retinal detachment and cataracts (especially at your age). The fact that it's bilateral is slightly concerning but shouldn't cause alarm until you've been thoroughly examined and tested. ...Read more

My pupil for my left eye fully covered my iris, can some one tell me why?

Dilated pupil: This is due to one pupil being dilated and the other normal, called anisocoria. You need an exam from an eyemd. This could be due to any number of things, from just being physiologic in you, trauma, inadvertent medicine in the eye, to different tumors around the eye and body. ...Read more

Can I just cover my dominant eye with a bandage and wear glasses to force my nondominant eye to focus?

Can I just cover my dominant eye with a bandage and wear glasses to force my nondominant eye to focus?

Lengthy time: The dominant eye is the guiding eye for focus and tracking. The focus shifts to the non-dominant eye when the dominant is covered. To force the non-dominant to become dominant requires continuous loss of the dominant eye for a years' time. This is an issue with eye injury, why would you want this shift to take place otherwise. ...Read more

Could I just cover my dominant eye with a bandage and wear glasses to force my left dominant eye to focus?

Yes but why: The body prefers to function with one eye being dominant and it appears that for you it is the right eye. Switching dominance takes up to a year of steady covering of the presently dominant eye. If you succeed what have you gained? There is no way to have double dominance - your brain will always pick one eye. ...Read more

Saw a black shadow in my eye when was focusing my sight in the objet and the other eye was covered. Is that normal. Am I getting blind?

See your eye doctor: Depending on how big that shadow is, it's time to see your eye doctor, and have a dilated fundoscopic exam done to see if you might have a possible posterior vitreal detachment, or just floaters in your visual axis. This can't be diagnosed in a forum, but an eye exam is easy to do, and will give you the most information and options. They'll check your vision too! ...Read more

Why do we need to cover eye injuries with eye pad?

Corneal oxygen: Pressure patching an eye with a corneal abrasion restricts the movement of the eye under the patch, while placing the capillary rich palpebral conjunctiva adjacent to the avascular cornea. Thus the patch improves healing of the corneal epithelium. Patching should never be used if infection is present, or the nature of injury suggests bacterial or fungal keratitis. Antibiotics should be used. ...Read more

Amblyopia: If you are beyond the age of 6 (to 10) years old this is useless therapy. Before the age of 6 yrs continuous patching is required and the improvement monitored. When there ceases to be any benefit from the patching, there is usually underlying disease other than amblyopia. ...Read more

I Just got my puppy and she was covered in ticks. I was taking them off using tweezers and one popped in my eye. I already flushed my eye?

I Just got my puppy and she was covered in ticks. I was taking them off using tweezers and one popped in my eye. I already flushed my eye?

Tricky ticks: Well it is summertime and the ticks are out, so a bit of prevention is always worthwhile. In your case, remember that there's a natural reflex for the eye to close when an object comes near - so I don't think the tick could have actually hit your eye ball? In any case, you washed the area thoroughly right after-so it would have been removed. If you have eye symptoms, see an ophthalmologist. ...Read more

I feel ticklish at my head. Just above my left eye. When I cover my eyes by using cotton or sponge, it tickles. And yes, I wear spectacles. Help. Tq?

Tickles on the head: You may just have a area on the skin of the face that is a little hypersensitive. There is really no pill or medicine to take to eradicate this. You just have to give it time. Try a skin moisturizer on the area. It just may be dry. Good luck. Feel better! ...Read more

If I look r to l I see a small white speck at one point & then it's gone. Happens with both eyes open & in each eye w/the other eye covered. Cataract?

Vitreous floater: The clear gel that fills eyeball is normally attached to the back of the eye. As we get older it can become more liquid (watery) and detaches from the back of the retina causing a floater of compressed gel or a weiss ring where it was attached to the back of the retina. Flashes can indicate a retinal tear. You should see your eye for worsening flashes floaters for a change in your side vision. ...Read more
