Frequently Asked Questions Contact Lenses<\/h1>\n\n\n\n
\n \n
\n \n If disposable contact lenses are still comfortable after the manufacturer\u2019s recommended wearing time has expired, can they still be worn? <\/summary>\n\n
\n

Wearing the lenses past the manufacturer\u2019s recommended wearing time increases the risk of infection, thus negating the benefits of disposable contact lenses. The very nature of disposable contact lenses means that you will continually have clean contact lenses upon replacement.<\/p> <\/div>\n <\/details>\n \n

\n \n Can my contact lenses be worn without removal? <\/summary>\n\n
\n

Certain contact lenses have been approved for 30 day extended wear. Wearing these lenses sleeping slightly increases the risk of microbial or infectious corneal ulcer. Wearers of these lenses must have their eyes checked at least every six months. Normal contact lenses should not be worn on an extended wear basis.<\/p> <\/div>\n <\/details>\n \n

\n \n How do I know if my contact lenses are \u2018worn out\u2019? <\/summary>\n\n
\n

Blurred vision, ocular discomfort and lens discoloration and deposits are common signs that a lens is approaching the end of its life. This can lead lens intolerance. Frequent replacement lenses should prevent these problems before they occur.<\/p> <\/div>\n <\/details>\n \n

\n \n Is there any age limit for wearing contact lenses? <\/summary>\n\n
\n

Contact lenses are usually used starting from age 11-12 years, because children of that age are already able to handle and take care of the lenses independently. There are some exceptions when lenses are used by younger children but it is not common.<\/p> <\/div>\n <\/details>\n \n

\n \n Can I swim while wearing my contact lenses? <\/summary>\n\n

\n \n Is it OK to play sports while wearing contact lenses? <\/summary>\n\n
\n

Wearing contact lenses for sports is a more flexible and stable form of eye correction than spectacles. In fact contact lenses give more peripheral vision than spectacles. If your sport involves vigorous exercise, a soft contact lens is an appropriate choice. If contact lenses are only worn occasionally, then use of a one-day lens, such as Acuvue 1 Day , Proclear 1 Day or Focus Dailies Aqua Comfort Plus lens, is most convenient.<\/p> <\/div>\n <\/details>\n \n

\n \n Can contact lenses come out of the eye with blinking? <\/summary>\n\n
\n

Once you have adapted to them, correctly fitted contact lenses should stay in position. However, they can come out under certain conditions. Rubbing your eye carelessly may result in a lost lens or you may push the lens under your eyelid.<\/p> <\/div>\n <\/details>\n \n

\n \n I am currently pregnant and am experiencing difficulty with my contact lenses. Is this normal? <\/summary>\n\n
\n

Pregnancy causes a change in hormone levels, which may impact upon your eyesight. Hormones can affect tear function, resulting in reduced or blurry vision. It is common to have a transient intolerance to contact lenses, particularly in the third trimester. The problem should resolve itself after childbirth. If the deterioration in vision persists, even after inserting new lenses, you should consult your eye care practitioner at once.<\/p> <\/div>\n <\/details>\n \n

\n \n Can patients with \u2018dry eye\u2019 problems wear soft contact lenses? <\/summary>\n\n
\n

Yes. However, you may have a reduced wearing time than someone with normal tear secretion. You can increase the comfort of your lenses by inserting eye lubrication drops. As always, it is best to consult your eye care practitioner for the best advice regarding whether you should wear contact lenses and what type of lenses may be suitable.<\/p> <\/div>\n <\/details>\n \n

\n \n Can a contact lens disappear behind my eye? <\/summary>\n\n
\n

No. It is impossible for a lens to disappear behind the eye, however a contact lens may displace under the eyelid. If this occurs, try looking in the direction of the lens to move it back to the correct position. If you wear hard gas permeable lenses, you may need to manipulate a displaced lens through the eyelid.<\/p> <\/div>\n <\/details>\n \n

\n \n Do you stock opticians own brand lenses? <\/summary>\n\n

\n \n Why don\u2019t new lens brands have a base curve of 8.6? <\/summary>\n\n
\n

The latest contact lenses are so slippery that the meaning of base curve (BC) has changed compared to before. The new lenses have such a smooth surface that with the common base curve of 8.6, they would simply fall out of the eye! Nowadays, base curve gives information about the lens material, not the lens size. The different base curves of new lenses fit equally well on the same eye, because they work together with other characteristics of the lens material. The world\u2019s smoothest lenses have a base curve, but their fit is just as good as the \u201cold\u201d, 8.6-curve lenses. But the bonus is the super smooth surface, which means a much more comfortable feeling.<\/p> <\/div>\n <\/details>\n \n

\n \n What does the abbreviation Dk\/t mean in the lens data? <\/summary>\n\n
\n

Oxygen transmission capability (Dk\/t) is an important indicator to pay attention to when choosing lenses. A contact lens forms a barrier that prevents oxygen from reaching the cornea of \u200b\u200bthe eye. It is important to know that the higher the Dk\/t value, the better. The higher the Dk\/t value, the more oxygen reaches the cornea of \u200b\u200bthe eye.<\/p> <\/div>\n <\/details>\n \n
