Sometimes contact wearers resort back to their glasses because of their blurry vision. A blurry contact lens can lead to frustration, stress and difficulty completing everyday tasks. Here are some possible causes and solutions to blurry vision while wearing contacts:
Deposits on the contact lens
Sometimes there can be a buildup of debris and protein deposits on the surface of the contact lenses. This is one of the most common reasons for lenses to seem cloudy and lead to blurry vision with contacts. The easiest way to see this problem is to take the contact out and compare the vision in your glasses. If you notice that your vision is clearer in your glasses than your contacts, then your contact lenses might be dirty.
Blinking your eyelids is the natural way to clean and lubricate the surface of your contacts while you are wearing them. However, it is also important to follow a careful routine to clean your contacts everyday when you remove your contact lenses.
Buildup and protein deposits can develop on the surface of contact lenses, especially when they have been worn longer than they were designed to be, or if they haven’t been cleaned properly every day upon removal. Even with careful cleaning, your contact lenses should be replaced according to your doctor’s recommended schedule (daily, two-week or monthly disposable) to minimize buildup and reduce the chance of damage to the eyes.
Dryness of contact lenses or eyes
Another answer to the question of "Why are my contacts blurry?" may be due to dryness. You can usually tell if dryness is the culprit of your blurry vision because your vision usually gets a little bit clearer after blinking. It is possible to rid this blurred vision with rewetting drops designed for your particular lens material.
If your eye itself is dry, sometimes this can cause blurred vision as well. Some people just do not produce many tears and suffer from dry eye disease. This can be treated with a prescription and over-the-counter medications.
There are some contacts lenses that are better for people who tend to have dryer eyes than others. Ask your doctor about other contact options. In addition, dryness derived from contact lenses tends to get worse as the lenses get older; in other words, be sure to replace your lenses as recommended.
Change in prescription
As people age, especially teenagers and those over the age of 40, their prescription changes. If your eyes are changing, your vision may be blurry. While prescription changes are more subtle and gradual than sudden, sudden changes in your prescription could indicate more serious eye or systemic health problems, like diabetes. If you feel like your prescription has changed, see a doctor to have your eyes examined and your contact lenses adjusted.
Eye health problem
When taking out your contact lenses, if you notice that your vision is still blurry, there might be a more serious eye health problem. Corneal swelling, infection, inflammation, cataracts, retinal problems and many other conditions may be the cause of the blurry vision. If such blurred vision occurs, see your eye doctor immediately!
With these common reasons, one can learn why his or her vision is blurry, cloudy or hazy in your contacts. Try to figure out what the possible cause may be and see your doctor is the problem persists.
