What Are Pros And Cons Of Contact Lenses?
Millions of people around the world wear contact lenses, though you wouldn't know it by looking at them. If you're unfamiliar with colored contact lenses, let us introduce you to these unseen but ubiquitous little helpers.
What Exactly Are Contact Lenses?
Contact lenses are thin, curved lenses that cover the tear film on the surface of the eye. The lenses are naturally clear, but are frequently tinted to make them easier to handle for the wearer. Contact lenses today are either hard or soft. Most people now wear the latter, but contact lenses were once made of glass! It was contact lenses.
Once we understand what contact lenses are, we must consider their benefits and drawbacks.
The Benefits Of Contact Lenses
- You won't have to worry about lens fogging, which is a common problem for eyeglass wearers when the weather changes.
- Some people prefer the natural appearance of contact lenses over glasses for aesthetic reasons.
- Contact lenses can help people with different prescriptions in each eye reduce eye strain.
- Contact lenses provide superior peripheral vision to glasses. This is especially true if your prescription is high.
- For those who participate in sports, contact lenses are less cumbersome.
- Specialized contact lenses can sometimes correct your vision better than glasses.
- While some contact lenses can cause dry eye symptoms if not chosen and worn correctly, specialty contact lenses can actually heal and soothe the surface of the eye, making dry eye sufferers more comfortable.
- Tinted contact lenses can be used for cosmetic purposes such as cosplay or in the film industry.
- While beautiful prescription sunscreens can be made for anyone, contact lens wearers have more sunscreen options.
Getting your first pair of contact lenses will feel like a huge step up from wearing glasses. Simply by wearing them, you will be able to see the world more clearly and will look fantastic. Contact lenses can be easily worn in your eyes, allowing you to perform many tasks that would be difficult with glasses, such as travel, sports, and so on.
However, if you do not use your contact lenses correctly, you may experience some side effects that may affect your vision in the long run.
Contact Lens Disadvantages
- Obstruction Of The Oxygen Supply To The Eye
The amount of oxygen reaching the eye is reduced because contact lenses lie directly on the eye and cover the entire cornea. A steady supply of oxygen is essential for keeping your eyes healthy.
Soft or silicone hydrogel lenses are preferable to traditional soft contact lens materials because they transmit more oxygen. In the long run, they may even be better for your eyes. Avoid wearing contact lenses for extended periods of time.
- Eye Dryness
Because contact lenses absorb the majority of our tears to keep themselves soft, they reduce the amount of tears on the cornea. Dry eyes result from a lack of tears, which causes itchiness, a burning sensation, and redness. If your eyes become too dry, it can cause corneal scarring, which can be extremely painful.
If you have chronic dry eyes, you can use eye drops to lubricate them and provide some relief. Irritation when Combined with Medication, especially Birth Control Pill
The use of birth control pills and contact lenses at the same time can result in chronic eye dryness and irritation. You will notice changes in the tear film, which is made up of three main layers that work together to protect, bathe, and nourish the eye's surface.
The combination of birth control pills and contact lenses can upset the tear film's balance, resulting in excessive tearing, burning eyes, and a gritty, foreign body sensation in your eyes. The reduced flow of oxygen to the eyes can aggravate the condition.
If you are taking birth control pills, you should avoid wearing contact lenses.
- Corneal Reflexes Are Weakened.
The use of contact lenses may cause a weakening of the corneal reflex in the eye. When the cornea is subjected to even the slightest pressure, the corneal reflex signals the brain to lower the eyelids to protect our eyes. The corneal reflex ensures that we close our eyes when something that could cause direct trauma to the eye, such as a flying object or someone attempting to poke us, occurs.
When you wear contact lenses all the time, your body learns to ignore the natural corneal reflex. This can dull the eye's response to the corneal reflex and result in eye damage if you are unable to close your eyes quickly enough in an emergency.
Reduce the use of lenses. Use your glasses at home to ensure that they do not impair your corneal reflex too much.
- Abrasions Of The Cornea
Contact lenses that are not properly fitted or that are too dry may scratch your cornea and cause corneal abrasions.
Sleeping with your contact lenses in place increases the risk of wear and tear. The lenses will attract dust and sand, which will irritate your cornea. These abrasions will allow bacteria and viruses to enter and cause eye infections, which can lead to vision loss.
When you insert or remove your contact lenses by accident, you may scratch your cornea. Wear your contact lenses with caution and never sleep with them in.
- Red Eye or Conjunctivitis
If you wear contact lenses for an extended period of time, especially at night, you are at risk of developing conjunctivitis and edema. They create a moist environment that can be a breeding ground for microorganisms like viruses and bacteria. Furthermore, because less oxygen reaches the cornea while wearing lenses, the body is less able to fight off infections caused by bacteria or viruses as effectively as it was previously.
The most common type of conjunctivitis in contact lens wearers is giant papillary conjunctivitis (GPC), which is caused by repeated contact lens irritation.
Before going to bed, always, always, always remove your contact lenses.
Ptosis is a condition in which the eyelids begin to drool and the patient is unable to fully open their eyes.
Contact lenses can migrate into the eyelid tissue, causing scarring and constriction, which can lead to eyelid retraction. This is especially true for people who wear hard contact lenses because the eyelid is stretched repeatedly when the lens is removed.
It would be a good idea to switch to soft contact lenses.
- Corneal Ulcer
This happens when an open ulcer on the cornea of the eye develops as a result of a fungal, bacterial, parasitic, or viral infection. Corneal ulcers can cause permanent blindness if not treated promptly. If it does result in blindness, a corneal transplant may be the only option for restoring vision.
Prevent Contact Lens-related Side Effects
Contact lenses should not be worn more than once and should be discarded or replaced as directed by your doctor. Remember that lens deposits will continue to accumulate on your contact lenses over time. The longer you wait to replace your lenses, the more lens deposits will form, reducing the oxygen supply to the cornea and eventually damaging the eye.
Contact lenses can produce unexpected results as long as we use them wisely and understand contact lens tips.
