What are the differences between annual and semi-annual disposable contact lenses?

Colored contact lenses are worn inside the eyes, so it is necessary to understand them. Is it better to wear them once a year or every six months? What are the differences between annual and semi-annual disposable contact lenses?

Is it better to use annual or half-yearly contact lenses?

Six-month disposable contact lenses are better than annual disposable ones, because annual disposable ones have a long usage time and will be much more worn out during wearing than six-month disposable ones. Even with daily care, there will inevitably be protein deposits that cannot be washed off, so these will cause annual disposable contacts to be less comfortable and safe than six-month disposable ones.

Semi-annual disposable lenses generally have a high water content, are softer, and have better oxygen permeability. However, a high water content also means that the eyes need to provide more water. Therefore, if some people have drier eyes, they are not suitable for contact lenses with a high water content. If the lenses are soft, they are also easy to break.

The difference between annual and semi-annual disposable contact lenses

1. Different water content

The annual disposable lenses have a low water content, so your eyes will not feel particularly dry when used.

The water content of semi-annual disposable lenses is relatively higher, and your eyes will feel drier when using them than annual disposable lenses, but the difference is not significant.

2. Different prices

The price of annual disposable is more expensive, but it is relatively cheap over the course of a year.

The price of semi-annual disposable is cheaper, but it only has a usage period of half a year, so it is relatively more expensive than annual disposable.

3. Different use experience

Since annual disposable lenses are used for a longer time, the lenses are not as soft and are a bit hard, but they are suitable for beginners who are not very good at operating them.

Semi-annual disposable lenses are relatively softer and feel better to use, but they are also more susceptible to breakage.

4. Different hygiene levels

If annual disposable lenses are used for too long, they will be severely worn out, more protein will be deposited, and the chance of causing eye diseases will be higher.

The usage time of semi-annual disposable contact lenses is half that of annual disposable contact lenses, so they will have much less wear and tear and are much more hygienic.
