The use of contact lenses as a visual aid is often chosen by some people because they are considered more practical than glasses. Types of contact lenses also vary, such as soft lenses and hard lenses. Although at first glance they look similar, these two types of contact lenses have some differences

Currently, the types of contact lenses that are commonly used are soft lenses and hard lenses. Maybe not many people know the difference between the two. In fact, soft lenses and hard lenses have their own functions as well as advantages and disadvantages.

The Difference Between Soft Lens and Hard Lens

Soft lenses are contact lenses made of plastic and water or water content. This water content is useful for providing oxygen to the cornea of ​​the eye, so you will feel comfortable when using contact lenses.

Meanwhile, a hard lens is a type of contact lens made of silicone-based plastic, allowing oxygen to enter directly through the lens into your cornea. The most popular type of hard lens is Rigid Gas Permeable (RGP).

Well, the most significant difference between the types of soft lenses and hard lenses is the shape. The diameter of the soft lens is larger than that of the hard lens.

Besides that, because they are made of different plastic materials, the texture of soft lenses and hard lenses is not the same. Soft lens texture tends to be softer and easily adheres to the eyes, so it can feel more comfortable when used.

Compared to soft lenses, the texture of hard lenses tends to be harder and firmer, so it may cause a lumpy sensation in the eyes, and you may need a longer time to get used to using it.

In terms of price, hard lenses are generally more expensive than soft lenses.

Which Type of Contact Lenses is Better?

Actually, whether or not the quality of contact lenses depends on the needs and eye conditions of the user. Therefore, before using contact lenses, you need to know the advantages and disadvantages of the following soft and hard lenses:

The advantages and disadvantages of soft lenses

In addition to being more comfortable and economical, another advantage of soft lenses is that the lenses are not easily dislodged or shifted in the eye. However, the thin texture of the soft lens makes the lens more prone to tearing, so you need to be careful when using it.

Using soft lenses for too long is also at risk of causing injury or irritation to the eyes due to lack of oxygen. Improper use of soft lenses is at risk of causing eye infections.

Therefore, if you want to use a soft lens, you should choose a soft lens with a water content that suits your eye condition. The water content in soft lenses can range from 38% to 75%.

Advantages and Disadvantages of hard lenses

The advantages of hard lenses are that they are more durable, not easily torn, and can give you sharper vision than soft lenses. In addition, this type of contact lens may also feel more comfortable and can improve vision better in people with cylinder eyes.

However, the smaller size of the hard lens lens can make it easier for these contact lenses to slip out of the eye and trigger the entry of dust or dirt under the lens.

Duration of use of hard lens contact lenses is relatively long, which is about 1 year, sometimes there can also be a risk of causing eye irritation, especially if these contact lenses are stored and used inappropriately.

No matter what type, both soft lens and hard lens, both can help overcome your vision problems. However, keep in mind that the use of contact lenses requires extra care and is more at risk of causing dry eyes, red eyes, eye infections, and wounds to the cornea.

Therefore, before you decide to use contact lenses, it is better to consult with an ophthalmologist, so that the doctor can determine which type of contact lens is more suitable for you.

When using contact lenses, both soft and hard lenses, don't forget to always take good care of your contact lenses and take them off when you go to sleep.
