The advantages and disadvantages of contact lenses
Contact lenses are placed on the cornea of the eye and correct refractive errors in vision (i.e. long or short sightedness). If you're sick of your glasses fogging up or you would like to try something different aesthetically, contact lenses could be a good alternative. However, they don't suit everyone.
Here are some of the main advantages and disadvantages of wearing contact lenses.
Advantages of contact lenses
- No fogged glasses from moisture or perspiration
- Modern contact lenses are very comfortable
- Some contact lenses can be worn overnight or for up to a month of continuous wear, meaning that they are little hassle and low maintenance
- Some eye conditions, such as keratoconus and irregular astigmatim, respond better to contacts than to glasses
- There are no annoying reflections or obstructions that may occur with glasses
- They allow oxygen to penetrate the eye
- Thicker glasses can result in a poorer side vision - both from the shape of the lens (which is strongest in the middle) and from the frames themselves. Contact lenses do not have this problem
- Contacts are great for sports players
Disadvantages of contact lenses
- Contact lenses are easily lost or damaged if they are not cared for properly
- Lenses can be expensive, particularly disposable and extended wear lenses
- Improper care can also lead to eye infections and complications
- Contacts may require special care for your opticians or eye specialist
- Some lenses need to be removed, cleaned and rinsed every night, which can be time consuming
- Eyes often require a break from lenses, so you won't be able to get rid of your glasses altogether
Making the right decision for you
Ultimately the decision to get contact lenses or not depends on your individual circumstances. If you are willing to devote the time, effort and expense needed to purchase and care for a pair of lenses, you shouldn't have any problems. Consult an optician for more details.
