I recently went to the eye doctor, and received a new prescription... it had been a few (8) years since I last visited an eye doctor. When I picked up my new glasses (2 pair) I find my vision is blurry when I cover my right eye, since it is 2 pairs of glasses, and it happens with both pairs, I am worried maybe the optometrist gave me the wrong prescription. My previous prescription (8 years ago) was L -225-100x110 R-275-075x70 - my new prescription is L -400-25x165 and R-400-25x020 is this a normal change? The most recent eye doctor is new to me, and I am beginning to doubt the prescription. Thank you.
Dr Langis Michaud's response:
My first comment would be that 8 years is way too long to wait for seeing an eye doctor. Every patient should be seen at the most every 2 years, not only for the vision problems but first and foremost to assess ocular health, which can evolve and change rapidly, without any alarming signs.
The changes you are showing here can be normal or abnormal, depending on your ocular health. I don’t know your age but it is a big factor to consider. If you are over 60, my first impression, with this type of change, is that you are beginning the process of developing cataracts. Cataracts, at the beginning, induce more myopia and changes astigmatism. This is what your prescription is showing. Even if the prescription is increased, sometimes, vision remains blurred because of the cataract. Previously, you could be less aware of this because your vision was already blurred by the prescription that was too low for this eye. With the increase in power, the vision is clearer but not perfect, probably because of a cataract, more evolved, on one side.
The best way to address this issue is to go back to your optometrist and ask your questions. I am quite sure that he will welcome you, will answer your questions and will address your concerns. Taking the time to talk is certainly a good way to start to resolve this problem. Perhaps he can’t do anything because of the cataract, but at this time, the best recommendation would be to consider surgery. Again, your optometrist knows your eyes better than anyone else. Consult him and ask questions.
