Contact lenses are popular because they improve your vision without affecting your appearance, making it easier to offer unobstructed views while engaging in outdoor activities and driving.
Do you know anything about the following myths of wearing contact lenses?
Q: Is it true that a person can only wear contact lenses for 10 years?
A: False! There is no deadline on how long you use contact lenses. It is true, however, that improper wearing and aging can both make it more difficult to wear contacts, due to a decrease in tear production that can cause dry eyes, corneal hypoxia or vascular hyperplasia.
💡 If you want to keep wearing contact lenses, you need to pay attention to the health of your corneas, get regular check-ups, and keep your eyes moist and healthy.
Q: Does long-time use of contact lenses cut off oxygen to the cornea?
A: Yes, wearing contact lenses for too long will indeed cause hypoxia of the cornea, resulting in swelling of the eye’s surface and changes in its shape, as well as corneal irritation, making it more difficult to wear contact lenses. In severe cases, it may even cause eye redness and blurred vision.
💡 Suggested NOT wearing contact lenses for more than 8 hours a day. If you really need to do so, we suggest you to choose highly breathable contact lenses. If you have any discomfort, please have your eyes examined as soon as possible.
Q: Is it better to select contact lenses with a higher water content?
A: It depends. Contact lenses with high water content naturally make you feel more comfortable. However, you should avoid them if you have dry eyes because it would draw moisture from your eyes and dry your eyes out quick.
💡 Contact lenses wearers who are prone to dry eyes or wear their contacts lens for a long period of time should choose more breathable lenses and in hydrogel formula.
Q : Are there any restrictions of using contact lenses?
A: Contact lenses aren’t suitable for people with specific vision problems, severe allergies that affect the eye, severe dry eye, eye disease or inflammation, or if you are in prolonged exposure to large amounts of dust, dirt, fumes and extreme dryness. You should not wear contact lenses during sleeping or shower. Pregnant women may have dry eye and temporary changes of corneas.
💡 Get consultation by our optometrists and have an eye examination before wearing contact lenses.
Q: WEARING CONTACT LENSES DURING WATER ACTIVITIES CAN CAUSE EYE INFECTION?
A: Yes. Water contains bacteria no matter it comes from the tap, swimming pool or the sea. Soft contact lenses have a high risk of bacterial or microbial contamination due to the hydrocolloid material. It would then increase the risk of eye infection. If you need to wear contact lenses during swimming, you may wear goggles and use disposable daily lenses to reduce the risk of infection. Replacing with a new pair of contact lenses after swimming is recommended.
💡 Regular water should not be used to clean contact lenses. You should sanitize or throw away the contact lenses if it contacts with water.
Q: Will coloured contact lenses damage the cornea?
A: It depends. If you want to wear colored contact lenses, please avoid choosing inferior lenses with pigments printed on the outer layer because it would cause friction and an allergic reaction and corneal epithelial cells may even fall off. High-quality colored contact lenses have the pigment sandwiched between layers so it does not come into direct contact with the eye.
💡 We suggest not buying contact lenses from unknown online sources or sources that aren’t FDA approved.
Q: Can I still wear coloured contact lenses after LASIK or SMILE surgery?
A: Generally speaking, it’s safe to wear contacts against one month after LASIK or SMILE. However, LASIK reshapes the cornea, flattening the centre 4-6 mm and changing the overall curvature. Ordinary soft contact lenses may no longer fit well or remain comfortably in place.
💡 An eye exam can help you find the right new lens.
