Selecting Artificial Tears Correctly

When feeling eye discomfort, the most common approach for patients is buying eye drops in the pharmacy. However, there are a variety of products available on the market. How do we select the most appropriate eye-drops? What is your first consideration when choosing eye drops? Is it packaging? price? Friends’ recommendation? Or ingredients? If your answer is the former, you should spend a few minutes reading the following.

Artificial tears are mainly divided into two types: unit-dose and bottle-type. The former one does not contain preservatives. It would not cause any side effects or toxic reactions so it can be used multiple times a day. Most of the bottle-type artificial tears contain preservatives, which is not recommended to use more than four times a day. Some new formulas using decomposable preservatives, which can break down into mild substances under light, have lower chance of having side effects. Moreover, some bottle eyedrops consist of a special designed bottle opening, which has a filter preventing from bacteria. There is no need to add preservatives and can be used multiple times a day.

In fact, different lubricants target on different dry eye problems. Some of them focus on moisturizing cornea, some can increase the viscosity and stability of the tear layer, and reduce the friction between the eyelid and cornea; some oily-based eyedrops can slow the evaporation of tears; and some contain repairing ingredients that damaged cornea accelerates healing.

Most importantly, it is better to consult your optometrists or ophthalmologists before using eyedrops. Incorrect use of eye-drops may cause serious consequences. For example, some eye drops labelled to solve red eyes contain ingredients that can narrow the blood vessels. Although the redness reduces immediately after use, this is just temporary and the cause of the redness could not find out. In fact, there are many reasons of getting red eyes, ranging from dryness, conjunctivitis, keratitis to acute glaucoma. The treatment and management can be very different depending on each case. Dealing with the symptoms only may delay the time getting suitable treatment.

In addition, the use of inappropriate eye drops, including contact lens drops, can damage or inflame the conjunctiva; some eye drops containing steroids, such as excessive or long-term use, can cause glaucoma or cataracts and other eye diseases. In severe cases, it may even cause vision. Permanently damaged. Therefore, if you have any questions when purchasing or using eye drops, you can check with your optometrist. Do not use eye drops!
