Often, it is accompanied by a sensation of dryness, burning, and itchiness. Pain and watery eyes are other symptoms. Blurry vision alone is not enough to diagnose dry eye syndrome but if it is paired with these other symptoms it can be an indication that you might have the condition.
One of the roles of tears is to prevent the cornea and the conjunctiva from getting dehydrated. When we blink, a layer of tears is spread over the eye. That’s what keeps it moist. The tear film has three layers: lipid, aqueous, and mucous. The first layer contains oils. The second one is a watery layer. The third consists of mucins. All these substances must come in the right proportion to keep the eye healthy and the sight clear. Based on the cause of dry eyes, the layer of tears can evaporate too quickly or it might not have the right balance of water, oil, and mucus. If tears are not spread all over the eye or if the oil and mucus concentration is too high, then the sight might become blurry.
If you experience blurry vision associated with dry eye, you can quickly blink a couple of time to apply a fresh layer of tears that will clear the eye. If you have other dry eyes symptoms, make an appointment with an ophthalmologist so you can get a correct diagnose and treatment.
