Well, yes, I have to say that cataracts can come back in some degree. Generally speaking, cataracts occur when there is a buildup of protein in the lens that makes it cloudy. And then it will just prevent light from passing clearly through the lens. In that way, it may lead to blindness. So we can say that it can be dangerous. But on the other hand, it can come back, for cataracts can be caused by irritants. For some serious cases, blurry vision, watery eyes may be possible too. Anyway, you need to pay more attention to it.
Don't worry, the eye cataracts can not come back again in someday after being cured by cataracts surgery. Owing to the natural lenses are removed and replaced with manmade lenses, and only the natural lens can result in a cataract, thus there is no possibility to give rise to cataracts. Maybe, you heard someone said he have an experience that cataracts come back. The truth is lens capsule may become cloudy a year or more after cataract surgery, which has similar symptoms to a cataract. Nevertheless, it is not a cataract actually. Hope you have a deeper understanding of cataracts after reading these.
Yes, it can work. Conjunctivitis, the so called pink eye, refers to infections of conjunctiva which is the clear layer. Conjunctivitis might be caused by bacterial, viral or allergic infection. The common symptoms of conjunctivitis include sensitivity to light, redness of eye, dry eye, stinging, eyelids swelling and foreign body sensation. In some cases, the infections could heal up without requirement of any treatment. For example, allergic conjunctivitis, can recover very soon if the patients are get out of touch with the allergens. As to bacterial or viral caused infection, oil of oregano can effectively help people by controlling the infection. It contains some anti-inflammatory agents which can alleviate swelling and irritations. It really works, yet you should consult with your doctor on how to use it and the proper dosage. Direct application to eyes might worsen the problem. There is something much easier and safer than the oil of oregano. You can use some salt water to wash your eyes and as warm compress. Normally warm compress can effectively help pink eye.
