Hold your upper eyelid with your other hand and lift it up. Use your middle finger to pull your lower eyelid down. Look up or straight ahead and place the lens directly on your eye. To centre the lens, slowly release your eyelid and blink several times.

You need to wash your hands again, look up at the ceiling, pull down your lower eyelid, pinch the lens with your thumb and index finger, and remove the lens.

Can We Use Contact Lenses Daily? Understanding Wear Schedules
Yes, contact lenses can be worn daily, but you must adhere to your doctor’s recommended wear schedule to avoid discomfort and eye infections. Understanding the appropriate type of lens and how long you may safely wear it each day is critical to preserving eye health.
Daily Disposable vs Monthly Lenses
The daily disposables are meant to be used once and then discarded, making them a very hygienic and convenient choice with no maintenance required, such as cleaning or storage. Monthly contact lenses, on the other hand, are meant to be reused up to 30 times, with daily cleaning and rinsing and overnight storage in fresh solution. It is up to you to decide between daily disposables and monthly contact lenses, depending on your lifestyle and budget, and with your eye care professional’s advice.
How Long Can a Contact Lens Be Used Safely?
Many people wonder if we can use contact lens daily, and the answer is yes, as long as you follow the correct hygiene routine and wear schedule advised by your eye care professional. Contact lenses can be used safely only for their recommended duration:
Daily Disposable Lenses
Wear them once, and then discard them. No need to clean them.
Monthly Lenses
They can be worn for up to 30 days, provided they are cleaned and stored daily.
Extended Wear Lenses
Some of them can be worn overnight, but this must be prescribed by your eye doctor.
Coloured or Cosmetic Lenses

When Should You Stop Wearing Contact Lenses and See a Doctor?
You need to stop using contact lenses if you continue to experience redness, pain, blurring of vision, swelling, or discharge from your eyes. These are major signs of a serious infection that requires immediate consultation with your doctor to avoid any long-term damage to your eyes.
Implantable Contact Lens (ICL): A Permanent Alternative
An Implantable Contact Lens (ICL) is a revolutionary vision correction procedure in which a specially designed lens is surgically inserted into the eye, in front of the natural lens. Unlike other contact lenses, which simply rest on the surface of the eye, the ICL is a long-term, removable solution for individuals with moderate-to-high myopia, hyperopia, or astigmatism. This procedure is ideal for people who are not suitable candidates for LASIK surgery but still desire to experience clear, sharp vision without the inconvenience of daily contact lens wear.

FAQ
Is it safe to wear contact lenses every day?
Yes, you can use contact lenses daily. You just need to make sure you take care of your lenses by maintaining good hygiene, cleaning them properly, and adhering to the daily wear schedule recommended by your eye doctor. Failure to do so may result in infections and serious complications.
Can sleeping in contact lenses cause infection?
Yes, sleeping with contact lenses can increase the risk of eye infections, as it reduces the amount of oxygen supplied to the cornea, which can cause bacteria to multiply quickly under the lenses, leading to serious infections like corneal ulcers and microbial keratitis, which can cause significant damage to your vision.
How often should you replace your contact lens case?
You should replace your contact lens case at least once every three months, as old cases can harbour harmful bacteria and biofilm even with regular cleaning. Using a worn or contaminated lens case is a leading cause of contact lens-related eye infections, so replacing it regularly is essential for maintaining good eye hygiene.
What are the early signs of a contact lens eye infection?
The early signs of a contact lens eye infection include redness, pain, unusual discharge, sensitivity to light, and blurry vision that does not improve after removing your lenses.
Are contact lenses good for the eyes in the long term?
Contact lenses are safe for long-term use when worn and cared for properly, but poor hygiene or prolonged overuse can gradually affect corneal health and increase the risk of complications.
