Contact lenses correct your eyesight without slipping off your nose every few minutes, the way spectacles do. With the improving technology the better lenses are being available; the use of contact lenses will only increase. The newer lenses are getting more comfortable, safer, and may provide a clearer vision, and yes, they are trendy as well. These days, the use of contact lenses is not limited to rectifying the vision, but they are also being used for aesthetic reasons. Whatever the reason, contact lenses are here, and they are here to stay!
With the increased use of contact lenses comes an array of problems. We all know the benefits of using a contact lens; let us peep into the world of contact lenses to see the limitations of contact lenses to help us make an informed decision.
Discomfort while wearing contact lenses may be due to an underlying eye disease or lens-related complications. If the lens is new, it is possible that they can be defective. It could be abnormally curved, have a scratched surface, or some other defect. If you are trying out a new brand of lens, then the tightness of the lens, the thickness of the lens, and/or the edge design of the lens can be a problem. Soft contact lenses, which allow for high oxygen permeability and can be worn for a long time, are a comfortable option.
One has to be wary of the age of the lens. Replace your lenses regularly as old lenses develop deposits, scratches, or nicks on their surface. Limiting the use of contact lenses to a maximum of 8 hours is also suggested.
An underlying eye disorder like an eye allergy, dry eye, blepharitis, conjunctivitis, eyelid problems, iritis, phlyctenulosis, or pterygium can also lead to discomfort. During such times, glasses must be worn instead of lenses.
2. Wearing duration
You might not always be able to wear lenses as long as you’d like. Certain situations such as poor air quality or low humidity make it increasingly difficult to wear a contact lens, especially one which is not new. The lens develops deposits at a faster rate and might develop protein deposits or other issues.
If you feel your eyes are getting too dry when you use lenses, you may try lubricating drops. It is always wiser to have an eye examination to rule out any other potential problem such as an infection or allergy. Always carry a spare set of glasses with you because under no circumstances should one be wearing a lens longer than it is comfortable.
3. Vision issues
Though contact lenses work well for most refractive problems, you might not be happy with the results if you have a condition like astigmatism. Also, lenses lead to issues like halos around lights at night or ghost images. Most people get used to them; however, these are not comfortable.
4. Allergy to contact lens
Allergies are fairly common when it comes to contact lens. A slight slack in the hygiene routine and your allergy might give way to an infection! The lens is constantly touching the eye, and the eye might develop an allergy to either the lens material, deposits on the lens, or to the solution used.
Wearing the lenses for a long time, improper cleaning of the lenses, using the old contact lenses for an extended period, and overly tight lenses may increase the risk of developing a corneal infection.
A corneal abrasion, even if tiny, acts as a gateway to pathogens.
So make sure you follow all the hygiene routine steps outlined by your eye doctor or optometrist while giving you the pair of contact lenses. On the slightest hint of eye irritation, remove them, rest your eye and visit your doctor!
