Effect of Contact Lenses usage

Contact Lenses

 Contact Lens

These are miraculous for people that don't just like the idea of wearing very cumbersome glasses and alternative eye-wear. Getting your 1st set of contact lenses would feel like a tremendous upgrade to eyeglasses. You can see the planet more clearly simply by popping them in and you'd look smart too! They can fit in simply onto the eye and permit you to perform varied tasks which may be uncomfortable in glasses like traveling, exercising, etc

To maximize their advantages and keep their side effects to a minimum, you ought to see your doctor frequently and make certain to use your lenses properly to avoid being exposed to some side effects that might even have an effect on your vision within the long run.

There are many ways in which wearing contact lenses can go wrong, however, one among the foremost harmful and common is wearing them for longer than you ought to. the former contains very tiny pores that trap fluids, gases, and different contaminants faraway from your eyes.

Over time with continuous use of contact lens, your lenses’ pores become clogged, they harden, and they begin to house bacteria. All of this could result in reduced performance, as well as risk to your sight. For this reason, it's essential that you replace your contact lenses often.

Even when cleaned, old contacts can create threats, putting your corneas at risk. While they're safe to use through the day, it’s best to allow your eyes enough time to rest.

Key facts

Your cornea is one amongst the sole places in your body that doesn’t get its much-needed oxygen from blood vessels. It gets it from the air instead.

When you wear soft contact lenses, a limited quantity of oxygen gets to your eye, that is ok until you shut those eyes for prolonged periods of time.

During sleep, between those 2 layers (your eyelid and the lens), no oxygen gets through at all. it's important to always contact a medical practitioner when these cases arise; Your doctor can tell if your cornea has been starved of oxygen by looking at it under magnification-“endothelial microcysts are amongst the symptoms that might be find.

If these issues persist for too long, your eye will be at increased risk of eye infection and corneal ulcers (open sores on the cornea).



Side Effects Associated With Usage Of Contact Lenses


  • Blockage of Oxygen Supply to the Eyes

Since contact lenses lie directly on the eye and cover the whole cornea, the amount of oxygen reaching your eyes will decrease.

Good oxygen supply is completely essential to keep the eyes healthy. You also might want to decide on modern silicone hydrogel contact lenses as these soft lenses are manufactured from a material that transmits a lot of oxygen than typical soft contact lens materials which may be safer for your eyes in the long run of usage. Avoid wearing your contact lenses for long hours at a stretch because it harms your eye.


  • Corneal Abrasion

Wearing your contact lenses night long or taking a nap with them will cause corneal abrasions or scratches on your cornea. As you can imagine, the condition is painful. This happens as a result of the contact lenses deny the corneas hydration and oxygen.

Never sleep with contact lenses in as the risk of abrasion can increase. The lenses can trap particles like dirt and sand and rub against your cornea.

These abrasions can produce a gap for bacterium and virus to seep through and give birth to eye infections, which can result in loss of vision too.


  • Blurred vision.

Another effect of contact lens overuse is blurred vision. Instead of aiding your vision, your contacts can impair your vision if you use it longer than required. This is caused by injury to your corneas and is usually accompanied by sensitivity to bright lights.


  • Red Eye or Conjunctivitis

This is one amongst the clearest indication of injury to the eyes. Factors such as crying, irritation, conjunctivitis, and lack of sleep naturally lead to reddish eyes, but the condition is temporary and heals between minutes and days. Red-eyes caused by contact lens overuse indicate a much more severe condition and may not be taken lightly.

Contact lens offers a moist atmosphere that acts as a potential breeding ground for microorganisms like viruses and bacterium.

Also, its noted that since less oxygen reaches the cornea when you wear lenses, the body doesn’t fight off an infection that is caused by bacteria or viruses as effectively as it should. Giant papillary conjunctivitis (GPC) is the most typical form of conjunctivitis that contact lens wearers get because of recurrent irritation from the contact lenses.

  • Dry Eyes And Eye Pain

Contact lens reduces the number of tears getting on the cornea as they absorb most of our tears to keep itself soft. This lack of tears causes dry eye syndrome resulting in itching, burning sensation, and redness of the eyes. If the eyes get too dry, it'll result in the scarring of the cornea which may be very painful. when one suffers from chronic eye dryness, it's advisable to use eye drops to lubricate the eyes to provide some relief to them.


  • Diminished Corneal Reflex

Using contact lenses might cause diminished corneal reflex within the eye. Corneal reflex is a protecting mechanism of the eye where the brain signals the eyelids to drop to shield our eyes whenever the slightest amount of pressure is applied to the cornea. Corneal reflex makes certain that we tend to shut our eyes if something could cause an instantaneous trauma to them, like a flying object coming towards our eyes or if somebody tries to poke us. When you use contact lenses always, you are teaching your body to ignore the natural corneal reflex.

This may dull the eye’s response to corneal reflex, that may lead to the eye being damaged if you can’t shut your eyes quick enough just in case of danger.


  • Irritation when Combined with Medication, especially Birth Control Pill

Concurrent use of contraceptive pills and contact lens together can lead to chronic dry eyes and irritation. You will experience changes within the tear film, which primarily consists of three main layers which come together to protect, bathe and nourish the eye surface.

The combination of birth control pills and contact lenses will upset this balance in the tear film and cause excessive tearing, burning eyes and a gritty foreign body sensation in the eye. The restricted flow of oxygen to the eye can worsen the condition.

Avoid using lenses as long as you're on the pill.

Corneal Ulcer

These open sores appear as white or greyish specks on the cornea. They occur once your eyes get infected because you used your contacts for too long or without cleaning them. They are painful and might cause blurred vision and visual impairment.

This occurs once an open sore caused by a fungus, bacteria, parasite infection or viruses is formed in the eye’s cornea. it can occur when your eyes get infected because you used your contacts for a long duration or without cleaning them. Corneal ulceration will cause permanent visual impairment if it's not treated quickly. If it does lead to blindness can cause blurred vision


How to take care of your contact lens

It’s necessary that you properly use and take care of your contacts. Although there are many various varieties of contacts, generally you should:

  • Use contacts according to the period prescribed
  • Handle contacts with good hygiene
  • Disinfect contacts as recommended
  • See an optometrist for regular eye exams

It’s necessary that you pay specific attention to the last point mentioned. Without a regular eye examination, eye diseases and conditions can go undiagnosed. A proactive approach is the best approach once it involves your eyes.
