Why Would Eye Drops Burn
Eye drops are a common ocular medication used for various eye conditions, from dry eyes to infections and glaucoma. While eye drops are generally well tolerated, some individuals may experience a burning sensation upon installation. Several factors can contribute to why eye drops might cause a burning feeling in the eyes, ranging from the active ingredients in the drops to individual sensitivities or improper application techniques.
Preservatives and Chemical Irritants
One common reason for eye drop-induced burning is the presence of preservatives or chemical irritants in the formulation. Some eye drops contain preservatives, such as benzalkonium chloride, to prevent microbial contamination and extend shelf life. However, these preservatives can be harsh on the ocular surface, leading to irritation and a burning sensation upon application. Opting for preservative-free eye drops can help reduce the likelihood of experiencing burning or discomfort.
Acidic or Alkaline Solutions
Certain eye drops, particularly those used for specific eye conditions like glaucoma or severe dry eye, may have acidic or alkaline properties to adjust the pH of the eye or enhance drug efficacy. The introduction of acidic or alkaline solutions to the sensitive ocular surface can cause a burning or stinging sensation upon contact. Ensuring proper administration and adherence to recommended dosing schedules can help minimize the discomfort associated with pH-altering eye drops.
Inappropriate pH Levels
Eye drops with imbalanced pH levels, either too acidic or too alkaline for the eye’s natural pH, can trigger a burning sensation upon application. The ocular surface maintains a delicate pH balance to support its health and function. When eye drops disrupt this balance, it can result in irritation, redness, and a burning feeling in the eyes. Selecting eye drops with pH levels compatible with the ocular environment can help reduce the risk of burning discomfort.
Allergies and Sensitivities
Individuals may have allergies or sensitivities to certain components present in eye drops, including active ingredients, preservatives, or additives. When exposed to allergens or irritants, the eyes can react by becoming red, itchy, and experiencing a burning sensation after using eye drops. Identifying and avoiding allergens through allergy testing or consulting with an allergist can help determine the specific triggers causing eye discomfort and burning reactions.
Overuse or Incorrect Application
Using eye drops more frequently than recommended or applying them incorrectly can also lead to a burning sensation in the eyes. Overuse of eye drops can disrupt the natural tear film composition, irritate the ocular surface, and result in a sensation of burning or stinging. Following precise dosing instructions, avoiding eye drop contamination, and proper instillation techniques are essential to reduce the risk of discomfort and burning with eye drop usage.
Discuss Burning with Your Eye Doctor
If you are using eye drops consistently and the drops burn when you use them, it is worth discussing with your eye doctor to see if there are alternatives that may not burn, if there are methods to minimize the stinging sensation, or if there is something that you are doing that makes the drops more noticeably painful. Your eye doctor is the best person to help decide when the drops should be stopped or changed based on the side effects you may be experiencing.
