Why Can't I Clean the Lens with Tap Water?
Tap water contains chlorine, impurities, microorganisms and metal particles. These substances may scrape the lens or remain on it, damaging the lens and injure the eyes; the microorganisms may even cause eye diseases. Therefore, please do not clean your contact lenses with tap water.
I have Worn the Lenses Up to the Recommended Replacement Schedule but the Lenses Still Look Alright. Can I Keep Wearing Them?
When you have worn the disposable contact lenses (daily, weekly, or monthly) up to their recommended replacement schedule, you cannot keep wearing them even they seem complete and without breakage. The lens will age after a while and a large amount of bacteria, dirt and eye discharge could have built up on it. Wearing it over the recommended replacement schedule could make the eyes uncomfortable or even cause infection. Therefore, we do suggest you to follow the replacement schedule to change your lens.
Are Contact Lenses Suitable for Sports and Exercise?
All exercise and sports such as ball games, running, jogging, hiking, cycling, etc., require steady, clear vision. Traditional glasses can slip or move easily during movement, become foggy and blurry with perspiration or in a humid environment, and the spectacles can even break in the middle of the game/exercise. Any of the situations above could cause disturbance and inconvenience. Hence, wearing suitable contact lens during sports/exercise is easy, safe and convenient. Clear vision effectively elevates sports performance.
When Should I Stop Wearing Contact Lenses?
- When feeling any discomfort in the eyes while wearing contact lens, the lens should be removed immediately.
- If there's any breakage on the lens, it should not be worn again and should be disposed of right away, and you should consult with your ophthalmologist.
- If there is any dust or foreign object on the lens, do not wear it until it is thoroughly cleaned, washed and sterilized.
- If the discomfort in the eye continues, you should not wear the lens again. Please consult with your ophthalmologist immediately and find out what the problem is, then address it to prevent any corneal damage.
