If you wear contact lenses, then you should read this

Since the time when Leonardo Da Vinci got the idea of contact lenses in 1508 and in 1801, Thomas Young developed the first contact lenses; humans have made improvement in this field by leaps and bounds. The first contact lens that were both comfortable to wear and widely available were produced in 1940s.


Lens helps us chuck the heavy specs in the bin and also give our eyes style and color (if you want). But there are many dangers of wearing the lenses for long periods of time and a recent study found something so gross that you might want to use your specs in order to read this.

So contact lens wearers beware and read this at your own expense.


1 Contact Lenses

Contact lens or what are simply known as contacts are a thin lens that is placed directly on the surface of the eye. These lenses can correct the vision, or can be worn for cosmetic reasons, such as changing the color of the eyes.

People wear contacts in order to avoid the hassles of wearing and carrying a pair of spectacles. Some also wear them in order to change the color of their eyes. Though contact lenses are better for peripheral vision when compared to glasses, they also come with a lot of do’s and don’ts.


Contact are also produced in a manner meant to be worn only for 4-6 hours and then disposed of, making them suitable for wearing at a function.

2 New revelations about contact lenses and bacteria

A new study has found that people who prefer wearing contacts have a higher risk of developing eye infections. Contacts have to be removed every night and kept immersed in a saline solution in order to avoid any contamination.

Wearers are advised not to wear them for long periods of time, as the eyes start to get irritated and may start to water. Also they are advised against touching the eyes for any reason, as the lenses may scratch the cornea.


The new study has found that wearing lenses can harbor many bacteria that normally don’t live in the eyes. These bacteria can severely harm the eyes and also cause the eyes to lose the eyesight. Bacteria like Pseudomonas and Acinetobacter were of particular concern as they can cause really bad eye infections and in extreme cases, even loss of eyesight.

The above video shows how many forms of viruses, bacteria and fungi can harm the eyes in different ways; some may even eat the eyeballs. This happens if you do not disinfect your contacts in the way specified by the doctor. The contacts trap these dangerous amoebas, viruses and fungi against the surface of the eye for long periods of time and this result in the slowing of the immensely quick immune response of the eye.


The bacteria, fungi and viruses eventually become immune and resistant to the disinfectant used to clean the contacts and the body’s immune system. This can lead to severe eye infection that can only be treated by a doctor. Failure to contact a doctor in case of discomfort may lead to blindness.
