Cataracts/Vision Loss

Do cataracts grow independently of one another in each eye? If one eye is good and if the other is bad, will using the good eye over time get worse since there's more strain on it? 

Also how do you distinguish between other eye conditions such as vision loss from glaucoma and temporal arteritis without an evaluation? It seems hard to tell if your vision is getting worse from cataracts alone or something else when you have cataracts.

    I am not a medical professional and I do not want to give medical advice.

    But if you have issues such as "vision loss," then you might want to find an excellent eye specialist (i.e. MD) who can provide an expert diagnosis.

    Good luck to you!

    Cataract left and right are independent but most people get both together or one side followed by the other quickly. Some people get them separately by several years.

    If your cataract has become very mature which means almost zero vision is left then u cannot know if you have only cataract or also other conditions. You better check this at an eye doctor.

    Since u are typing this message I supposed your vision is still ok to read close objects but not far ?

      Appreciate the reply. My cataracts is worse in the right eye, I can still see well in the left eye. But these days it seems that my vision in the good eye has gotten worse as well. I've always been nearsighted so I can read near without glasses, I wear glasses for distance. I also have astigmatism and double vision so that makes seeing harder with dry eyes.

      Been holding off on surgery for a bit since having only one eye done I figured would be weird. I'd like to keep the natural lens in the good eye till it gets worse but seems like it's almost time to book the surgery.

    I believe you can develop a cataract in just one eye.  I don't believe using one eye will cause you to develop a cataract in that eye, as cataracts are not caused by using your eye(s).  As for determining the cause of vision loss, the only way to know that is to have an eye exam.
