Are cosmetic contact lenses disposable? Are those with a water content of 38 % good?

When buying cosmetic contact lenses, there are many factors to consider. Are cosmetic contact lenses disposable? Are cosmetic contact lenses with a water content of 38 good?

Are cosmetic contact lenses disposable?

1. There is a one-time

Disposable contact lenses are mainly daily disposable contact lenses. Disposable here does not mean that you cannot use them after taking them off. Instead, it means that they can be used within 24 hours from the moment they are opened. You can take them off and put them on again, as long as it is within one day. Daily disposable contact lenses are thinner and have a higher water content than other contact lenses with a long usage time. Of course, the damage rate will also be higher than that of contact lenses with other expiration dates.

2. Non-disposable

The shelf life of weekly, monthly, and annual disposable contact lenses is longer than that of daily disposable ones, and they can be worn repeatedly. However, they are mainly usable within the shelf life. If they exceed or are close to the shelf life, it is best to buy a new one. The durability of these contact lenses with a longer shelf life is closely related to their shelf life. Compared with daily disposable contact lenses, they require more care, such as daily care, lens cleaning, etc. If these are not done well, it will be uncomfortable to wear your eyes.

Is it good to have a water content of 38 in cosmetic contact lenses?

38% is a low water content and is suitable for long-term wear. A water content of around 38% is just right for wearing for more than 7 hours. The higher the water content of the contact lenses, the more hydrated they are, and the more moisturizing they feel when worn. Moisture content is often expressed as a percentage. Usually, a moisture content less than 38% is low moisture content, 42%-60% is medium moisture content, and above 60% is high moisture content. But don't make the mistake of thinking that the higher the water content, the better. Because as the wearing time increases, the moisture in the lens and the eye fluid are exchanged, and the high water content lens evaporates due to exposure to air. The lens will absorb eye fluid and cause dry eyes and discomfort.

(1) Short-term wear: If you only wear them for a short time (about 3 hours), you can choose contact lenses with high water content, which will be more comfortable.

(2) Long-term wear: If you wear it for a long time (more than 7 hours), you can choose contact lenses with a water content of about 38%, which will be more suitable.

Okay, that’s all the introduction about colored contact lenses. I hope you all understand it.
