Lubricant eye drops
I wear both glasses and multifocal contact lens
I had my annual eye exam in April and had a slight prescription change in my left eye (-4.25 to -4.50).
About a week ago, I started experiencing some blurriness in the left eye. I went to my optometrist who noted that the left eye had a lot of mucus and the white was swollen.
He did a dilation exam and noted that nothing ominous was seen. We treated it as an infection. The blurriness improved but the vision in the left eye was still off. When I mentioned this at my follow-up exam, we did some additional testing and noted that the left eye prescription was now (-4.75).
He also mentioned that the left eye was extremely dry and is attributing the prescription change to dry eye syndrome. Is this possible?
Thanks for your Question
Eye infection can cause dry eyes. Eye drops with preservatives can also cause dry eyes. Dry eyes can cause changes in refractive power mainly myopic shift and sometimes more astigmatism.
You have to use preservative free artificial tears at least 5 times a day for 2-3 weeks. You can try systane eye drops, optive eye drops or refresh tears eye drops.
