Using contact lenses is an easy, comfortable and safe option for achieving optimal vision all day long. Contact lenses provide you with a wide variety of replacement options, according to your vision preferences, and offer the following advantages:

  • Clear sharp vision, even in low light.
  • Absence of glare and distortions that can sometimes appear with glasses.
  • They quickly adapt to your lifestyle, since you can wear them when playing sports, partying, watching TV, etc.
  • Daily lenses: designed more for occasional wear (such as playing sports or for weekends), or for users who suffer from allergies. The main advantage is that this replacement option does not require cleaning solution, since you only use the lenses once.
  • Monthly lenses: Designed for continuous wear. They can be used for a month and require maintenance
  • Contact lenses for myopia: spherical lenses with negative dioptres that help you to see objects in the distance clearly.
  • Contact lenses for hyperopia: spherical lenses with positive dioptres that help you to see objects up close, without losing the clarity of your vision with objects in the distance.
  • Contact lenses for astigmatism: toric lenses with a special geometric shape to help correct the visual defect and achieve clear vision at all distances.
  • Contact lenses for presbyopia or eye strain: If you are over 45 years old and need different prescriptions in order to see clearly both up close and at long distances, you can use multifocal or varifocal contact lenses.

Hydrogel silicone contact lenses use the latest technology to allow more oxygen to pass through to your eyes, as they are highly permeable to oxygen and provide greater hydration. They will be more comfortable to wear in comparison with other contact lenses made from conventional materials.

How to put in contact lenses

  1. Wash your hands: Whenever you need to handle contact lenses it is very important to maintain good hygiene, in order to avoid contaminating your contact lenses.
  2. Always make sure you know which lens corresponds to which eye, and make sure you don’t get them mixed up.
  3. Place the lens on the tip of your index finger, and with your middle finger slide down your lower eyelid. Use your free hand to hold open your upper eyelid. You can now place the lens onto your eye and gently release both upper and lower eyelids. After a few seconds blink several times, and the lenses will be correctly placed on your eye.

How to take out contact lenses

  1. You will need to wash your hands again in order to remove your lenses, as you will need to touch your eyes and lenses again.
  2. Use one hand to lift your upper eyelid. Use your free hand to slide the lens downwards with your middle finger, and use your index finger and thumb to pinch the lens and remove it gently.

Some myths about contact lenses

Can my contact lenses go behind my eyeball?

That’s impossible. There is a membrane called the conjunctiva that covers the white of the eye that prevents this from happening.

Can my contact lenses fall out of my eyes?

It is highly unlikely that this would happen with today’s soft contact lenses.

  • Always wash your hands with water and soap before touching contact lenses.
  • Use a fresh dose of contact lens cleaning solution every time that you put your lenses in. (Unless you use daily lenses).
  • Never use tap water, sterilised water, saliva, saline solution or moisturising eye drops. None of these products are appropriate for correctly disinfecting and cleaning contact lenses.
  • Rinse the lens case with cleaning solution and leave it open and on its side so it can dry.
  • Don’t clean the case with water, as it may contain impurities and microorganisms. Also avoid leaving your lens case in the bathroom or in humid places where mould and germs may accumulate.

Bear in mind that the maintenance and cleaning plan may vary according to the type of material. To be sure, follow the instructions from your optician or optometrist.
