Blepharitis can lead to dry eye, so the best eye drops for blepharitis are artificial tears. Ideally, using preservative free artificial tears is better than artificial tears that do have preservatives. Blepharitis is caused by meibomian gland dysfunction, which is often abbreviated as MGD. There are a select few brands of tears, such as the Optase MGD Advanced Dry Eye Drops, that are focused on helping to treat MGD. These drops can be helpful in breaking the blepharitis and dry eye cycle.
Blepharitis, MGD (Meibomian Gland Dysfunction), and dry eye are not the same, but they are related to each other
Blepharitis is an inflammatory condition that affects the eyelid margins, causing redness, swelling, and irritation. It can be caused by bacterial overgrowth, allergic reactions, or other factors. Blepharitis can cause dry eye symptoms and may also affect the function of the meibomian glands, which produce the oil that forms the top layer of the tear film.

MGD, on the other hand, is a condition that specifically affects the meibomian glands. In MGD, the meibomian glands become blocked or dysfunctional, leading to a reduction in the production of the oil layer of the tear film. This can cause evaporative dry eye and other symptoms, such as eye discomfort, irritation, and redness.
In some cases, Blepharitis can contribute to MGD by causing inflammation and dysfunction of the meibomian glands. Conversely, MGD can contribute to Blepharitis by altering the composition of the tear film and making your eye feel very dry.
However, it’s important to note that while artificial tears can help manage the symptoms of blepharitis, they do not treat the underlying condition. Blepharitis requires appropriate treatment by a healthcare professional, which may include eyelid hygiene, topical or oral antibiotics, or other therapies aimed at reducing inflammation and addressing the underlying cause of the condition. Therefore, if you think that you have blepharitis, it’s important to seek professional advice from an ophthalmic professional.
