If you’re one of the unlucky ones who’ve been told that contact lenses aren’t for you, you should know that it’s now possible to correct almost any problem. Myopia, astigmatism, hyperopia, presbyopia, and any combination of these refractive problems can be addressed thanks to contact lens innovations that open the door to freedom without glasses!
Contact lens manufacturers are very proactive and have developed several types of lenses that correct more problems while accommodating patients’ evolving lifestyles.
The increasing incidence of dry eyes, closely linked to prolonged exposure to screens, has led to the development of next-generation contact lenses that better reflect this new reality.
Many contact lens wearers had stopped using them because of the discomfort caused by materials incompatible with the reduced blinking frequency that comes with watching screens.
Thirty years ago, people replaced their contact lenses annually. Today, the majority of wearers have access to daily disposable lenses. This type of lens allows for the correction of almost all prescriptions and care products which, in the long term, can cause some form of allergic reaction to cleaning products or preservatives.
The cost of daily disposable lenses is no longer a problem. Several products are now available and as a result, a healthy competition has been established between the various manufacturers. What’s more, it’s now possible to recycle contact lenses as well as packaging in order to reduce the associated ecological footprint.
Innovation does not stop at materials or the development of parameters that correct all vision problems. Johnson & Johnson has introduced a drug-releasing contact lens (Theravision lens) that relieves seasonal allergy symptoms while correcting vision. There are also contact lenses that slow down the progression of myopia in teenagers.
It’s also possible to use semi-rigid scleral lenses in patients with acute astigmatism, keratoconus, corneal dystrophy or a cornea transplant. This type of lens is also used by patients suffering from moderate to severe dry eye. This type of contact lens is much more comfortable than the traditional semi-rigid lens because it does not touch the cornea, the most sensitive part of the eye. It rests on the conjunctiva which covers the sclera (white part of the eye) and covers the cornea without touching it.
Contact lenses that correct presbyopia also correct myopia or hyperopia. Moreover, some types of lenses can also correct astigmatism. Therefore, it’s possible to optimize your vision regardless of the condition.
The optometrist will prescribe the type of contact lenses based on the following parameters:
Then, the optometrist or optician will place sample contact lenses on the eyes and check for position, movement, and vision before placing the order.
