Give Your Eyes a Fresh Outlook
Dry eye is an uncomfortable condition that occurs when your eyes do not produce enough tears, or the tears they produce are not high enough quality. Tears that do not have the proper chemical composition may evaporate too quickly, exacerbating symptoms of dry eye.
Additionally, a good quality tear film plays a significant role in keeping the eyes lubricated and washing away bacteria and debris.
The tear film is a thin layer covering the outside of the eyeball. The tear film has a similar composition to saliva, containing various enzymes designed to keep the eye moisturized.
Tears are made up of 3 layers, a thin lipid layer, a thick aqueous layer, and an innermost hydrophilic mucin layer. Each layer works together to wash away bacteria and keep tears from evaporating too quickly.
Some common symptoms of dry eye may include:
- Red, inflamed eyes
- A dry, irritated, or itchy feeling in one or both eyes
- Sticky, discoloured discharge
- Overly watery eyes
- Sensitivity to light
