Contact lenses sit directly on the cornea, just like prescription glasses, helping to correct vision by adjusting the focus of light entering the eye. When used properly and with proper care, they offer a safe and effective alternative to glasses. Whether contact lenses are the right solution for you depends on your vision needs and lifestyle.
How Do Contact Lenses Work?
Contact lenses are small prescription lenses that rest on the tear film of the eye. Their primary purpose is to correct vision problems while maintaining eye health. While they may seem like tiny glass-like disks, they function much like traditional glasses—bending and focusing light so that objects appear sharp and clear.
Why Choose Contact Lenses?
Unlike glasses, contact lenses move with your eye, providing natural, unrestricted vision. They are available in various designs to meet different needs, including:
- Daily, bi-weekly, and monthly lenses
- Lenses for specific conditions, such as astigmatism, nearsightedness, and farsightedness
Your choice depends on how often you want to replace your lenses, as well as your eye sensitivity and prescription needs.
Types of Contact Lenses
Soft Contact Lenses
These are the most commonly prescribed lenses today. They are made from moisture-retaining materials, keeping them soft and flexible while allowing oxygen flow to the cornea.
- Daily Disposable Lenses – Convenient and hygienic, as they are replaced every day. Although slightly more expensive, they reduce the risk of infections.
- Bi-Weekly and Monthly Lenses – Designed for extended use with proper cleaning and storage.
Rigid Gas Permeable (RGP) Lenses
Less common but offer sharper vision for those with high prescriptions or corneal irregularities. They last longer than soft lenses but require an adaptation period.
Toric Lenses (for Astigmatism)
Specially designed to correct astigmatism, providing better stability and focus than regular lenses.
Multifocal Contact Lenses
For individuals who need both distance and near vision correction, offering a seamless transition between focal points.
Essential Contact Lens Care
For eye health and safety, follow these important guidelines:
- Always wash your hands before handling your lenses.
- Use only approved contact lens solution—never rinse with water or saliva.
- Clean and disinfect reusable lenses daily to remove buildup and bacteria.
- Never sleep in contact lenses unless they are specifically designed for overnight wear.
- Replace your lens case every three months to prevent bacterial contamination.
Improper care can lead to temporary or even permanent eye damage, so proper hygiene is crucial.
Common Mistakes to Avoid
- Wearing lenses overnight – Sleeping in contacts significantly increases the risk of corneal infections.
- Ignoring discomfort – If your eyes feel dry or irritated, remove your lenses and check for deposits or damage.
- Overusing disposable lenses – Daily lenses should never be used beyond one day.
