What Is Dry Eye and How to Treat it?

The eye has a major tendency to depend on the flow of tears to supply constant moisture and lubrication to maintain unobstructed vision and eye comfort. Tears are a mixture of water, for moisture; oils, for lubrication; mucus, for proper and equal spreading; and antibodies and specific proteins, for resistance to infection. These elements are secreted by unique glands positioned around the eye. When there’s an imbalance within this tear flowchart, someone sooner or later ought to experience dry eyes.
When tears do not adequately lubricate the eye, you will perhaps experience:

  • Pain
  • Light sensitivity
  • A gritty sensation
  • A feeling of a foreign body or sand inside the eye
  • Itching (which may be chronic in nature)
  • Redness of your eyes
  • Blurring of vision

From time to time, someone experiencing a dry eye may have excess tears running down the cheeks, which may seem very confusing. This happens when the eye isn’t getting adequate lubrication. The eye sends a distress signal by way of the nervous framework of our body for more supply of lubrication. In response to this SOS message, the eye is flooded with tears to try to compensate for the underlying dryness. Nonetheless, these tears are mainly water and do not have the lubricating qualities or the rich composition of regular tears. They may wash debris away, but they will not coat the eye surface correctly. Furthermore, mainly because these emergency tears tend to arrive as well late, the eye is in desperate need to regenerate and therefore immediate treatment is vital.

What Causes Dry Eyes?

Long-term usage of contact lenses is an additional trigger; in reality, dry eyes would be the most typical complaint among lens wearers. Recent analysis indicates that dry eyes and wearing of contact lenses has the potential to be a vicious cycle. Dry eye syndrome actually makes the wearing of contact lenses uncomfortable, and also the rubbing of the lenses against the conjunctiva appears to be a major reason for dry eyes.

Incomplete closure of your eyelids, eyelid disease and also a deficiency with the tear-producing glands are some of the other causes. Tears are composed of three layers: the outer, oily, lipid layer; the middle, watery, lacrimal layer; as well as the inner, mucous or mucin layer. Every single layer is created and produced by a unique part of the eye (the lacrimal gland produces the lacrimal layer, one example for your reference), so an issue with any of these sources can lead to dry eyes.

Dry eye syndrome is most typical in ladies, possibly resulting from hormone fluctuations. Current analysis suggests that smoking, also, can raise your danger of dry eye syndrome. With ever increasing popularity of eyelid surgery (blepharoplasty) for improved look, dry eye complaints now occasionally are linked to incomplete closure of eyelids following a procedure.

Tears bathe the eye, washing out dust and debris and helps in keeping the eye moist. Additionally they contain enzymes that neutralize the microorganisms that colonize the eye. Tears are critical for very good eye health. In dry eye syndrome, the eye doesn’t create enough tears, or the tears possess a chemical composition that causes them to evaporate too soon when compared to the tear produced in a healthy and unaffected eye.
