Answers Your Dry Eyes Questions

Q: Is it true that Dry Eye symptoms seem to be more severe in the winter than in the warmer spring and summer months?

A: Often times this is true, but some folks, like contact lens wearers, can be dry any time in the year.

Q: When should a person come in to see their optometrist for Dry Eye symptoms and when is
it enough to take care of this problem yourself?

A: Non contact lens wearers should come in when the symptoms are bothersome or affect their daily routines. Contact lens wearers should come in sooner to avoid possible infections or for a brand refit if necessary.

Q: What is the examination like to determine whether someone is suffering from Dry Eyes?

A: A dry eye evaluation will include an assessment of the amount of tear available, the amount of evaporation that occurs within a specific timed test and an evaluation of the lid margins with a microscope to check for lid diseases like meibomitis, demodex or blepharitis.

Q: I have a friend in whose eyes are frequently overly watery. That isn’t Dry Eye, is it?

A: Yes, excessive tearing can happen with dry eyes or a blockage of the drainage system. When you have dry eyes, it causes irritation, esp. in wind or cold weather. This can cause the eye to increase the amount of tear or liquid. Excessive tearing may also be due to a blockage of the nasal canal.

Q: What are the typical treatments used to help people suffering from Dry Eyes?

A: Depending on the cause of the dry eye, treatment can be done by increasing the amount of tear available, decreasing the amount of evaporation, an occlusion of the drainage system to prevent loss of tear or all three.

Q: Are some people more prone to having Dry Eyes than others?

A: Women are 8x times more prevalent due to hormone imbalance. Certain eye or systemic diseases can result in dryness and some medications like anti-anxiety and anti-depressants can induce dryness.

Q: Do you have any recommendations for people to help them avoid Dry Eye issues?

A: Blink often, take more computer breaks, stay hydrated, decrease caffeine, wear sunglasses in windy conditions.
