Artificial tears

From WikiMD's Wellnesspedia

Artificial tears are a type of eye drops used to lubricate dry eyes and help maintain moisture on the outer surface of the eyes. They are often used to relieve dry eye syndrome and other eye conditions.

Composition[edit | edit source]

Artificial tears are usually composed of water, salt, and polymers that provide viscosity. They may also contain preservatives to prevent bacterial growth or buffering agents to adjust pH. Some brands of artificial tears are hypotonic, meaning they have a lower salt concentration than human tears, which can help soothe irritated eyes.

Types[edit | edit source]

There are two main types of artificial tears: those that contain preservatives and those that do not. Preservative-free artificial tears are recommended for those who use artificial tears frequently, as they are less likely to irritate the eyes. However, they are typically more expensive and have a shorter shelf life than artificial tears with preservatives.

Uses[edit | edit source]

Artificial tears are used to treat dry eye syndrome, a condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. They can also be used to relieve eye discomfort caused by computer use, reading, and exposure to wind or sun.

Side Effects[edit | edit source]

While artificial tears are generally safe for most people, they can cause side effects in some cases. These may include blurred vision, eye redness, or discomfort. If these side effects persist or worsen, it is recommended to consult a healthcare professional.
