Dry eye
Your tears serve multiple purposes. They help protect your eyes from microorganisms and debris, lubricate the surface of your eye, help provide clear vision, and nourish the surrounding tissues. Dry eye occurs when the tear film (made up of oil, water, and mucus) either isn’t sufficient, or evaporates too quickly. It may make your eyes feel gritty, irritated, inflamed, watery or cause blurry vision. If you wear contact lenses and experience dryness symptoms, it may exacerbate the discomfort or cause the lenses to feel like they’re sticking to your eyes more.
What may cause it:
- Environmental factors like low humidity
- Excessive screen time leading to reduced blinking
- Aging—tear production may decrease with age
- Certain medications or diseases
- Contact lens wear
If you’re experiencing dryness symptoms frequently when you wear contact lenses, let your eye doctor know. They may perform dry eye assessments, recommend a different type of contact lens, and/or recommend another vision correction type altogether.
