Blurry vision with contact lenses: Causes and solutions
Just like eyeglasses, contact lenses are supposed to provide perfect correction for visual problems.
Indeed, when properly adapted, contact lenses offer optimum vision.
However, there are various reasons why it is possible to see blurred when wearing contact lenses, the main ones being as follows.
New contact lenses
Even if it's not often the case, blurred vision can occur when wearing new contact lenses.
The reason for this is that the eyes have to adapt to the new equipment placed directly on their surface.
What's more, the brain also has to assimilate the new visual information it receives.
All these sudden changes can lead to imprecise and foggy vision.
However, once the period of habituation over, the blurred vision disappears in favour of perfect sharpness.
If this is not the case, it is advisable to visit your optician to find out the reason for this altered vision.
Unsuitable contact lenses
It is clear that contact lenses that do not give you completely clear vision are unsuitable.
If you're trying out new lenses, it's essential to let your optician know straight away so that they can provide you with a more suitable pair.
However, it can also happen that your usual contact lenses, with which you have always seen properly, suddenly fail you.
Over time, you're seeing less clearly with them, and your vision is becoming blurred.
This may mean that your eyesight has changed and that your contact lenses are no longer suitable.
If this is the case, it is essential to visit your ophthalmologist for an eye test.
The eye care professional will then be able to write a new prescription for contact lenses that are adapted to your new visual acuity.
The contact lens is dirty
Apart from daily lenses, contact lenses need to be cared for regularly and properly.
Lenses need to be disinfected in a suitable solution to ensure they are clean before being placed on the eye.
What's more, they should always be handled with clean, dry hands.
A soiled contact lens can cause considerable discomfort, as well as blurred vision.
If this is the case, the lens should be removed immediately for examination and cleaning.
The contact lenses are incorrectly positioned
It's essential to pay close attention when fitting contact lenses, to make sure you put them in correctly.
Indeed, inverting the left and right lenses or placing the lens off-centre on the eye can affect vision.
Blurred vision can thus result from incorrect positioning of the contact lens.
If this is the case, the lenses should be removed immediately so that they can be repositioned correctly.
