In recent years, contact lenses have become an essential part of daily life for many people, whether for medical or cosmetic purposes. They offer freedom of movement without the need for glasses, provide a wider field of vision, and add an aesthetic touch for those who wish to change their eye color. However, despite their widespread use, some people experience discomfort or eye irritation, often due to choosing the wrong lens or misuse.
If you are thinking of trying contact lenses for the first time or want to change your current type, this article will put in your hands a comprehensive guide to help you choose a comfortable and safe lens, away from randomness and non-medical advice.
1. Get a complete eye exam before buying lenses.
The biggest mistake many people make is buying contact lenses without a prescription.
Even if the eye is healthy, there are important factors such as:
- The percentage of oxygen needed by the cornea
- Degree of eye curvature
- Suitable lens diameter
- Allergies or persistent dryness
These details cannot be known without a specialist examination.
The doctor will determine the best type and show you whether your eyes are suitable for daily, monthly, or seasonal use.
Very important:
Do not buy lenses from the internet or from your friend "because they suit her", every eye has different circumstances.
2. Choose the type of lenses according to your daily needs.
There are different types of contact lenses , and each type has its own purpose:
✔ Daily lenses
- It is used only once.
- Best for those with sensitive eyes or beginners.
- It does not require a solution or cleaning.
✔ Monthly lenses
- Economical for those who use lenses continuously.
- It needs daily cleansing and good moisturizing.
✔ Annual lenses
- It lasts longer but requires careful maintenance.
- Not suitable for those with frequent allergies.
✔ Colored cosmetic lenses
- To change eye color.
- Comfort or health should not be sacrificed for the sake of appearance.
✔ Medical lenses
- It treats nearsightedness, farsightedness, or astigmatism.
- A precise prescription from an ophthalmologist is required.
Remember: Choosing the type depends on your lifestyle, not just the price.
3. Ensure the lens has sufficient oxygen permeability.
The cornea has no blood vessels; it breathes oxygen from the air.
If the lens has low permeability, you may experience:
- drought
- redness
- Burning
- annoying headache
- Blurred vision
4. Choose lenses that are able to retain moisture.
The ideal lens doesn't dry out quickly.
High-quality models contain moisturizing technologies that prevent evaporation and help to use the lens for hours without discomfort.
If you wear lenses for more than 6–8 hours a day, moisturizing lenses are an essential option.
5. Observe the degree of curvature of the lens.
The degree of curvature of the lens determines how well the lens conforms to the surface of your eye.
A lens that is too large may “swim” inside the eye, and one that is too small may cause pain or scratch the cornea.
6. Lens cleanliness is just as important as choosing the right lenses.
Comfortable lenses become harmful if their cleanliness is neglected.
Basic instructions:
- Wash your hands with soap before touching the lens.
- Use a specialized lens solution, not tap water.
- Do not place the lens in plain water or non-medical eye drops.
- Do not use the lens beyond its expiry date.
Absolutely forbidden:
- Sleeping with lenses not designed for that purpose
- Using the lens if it fell to the ground without sterilization
- Sharing lenses with anyone
7. Do not sleep in contact lenses unless they are specifically designed for that purpose.
The cornea needs oxygen during sleep.
Traditional lenses restrict airflow and cause:
- Keratitis
- swelling
- severe irritation
- Risk of bacterial infection
8. Your adherence to the usage period is more important than the quality of the lens.
Daily lenses are not monthly, and monthly lenses are not annual.
Continuing to use an expired contact lens is equivalent to wearing a plastic mask over the eye.
in the end
Choosing comfortable and safe contact lenses starts with medical safety, not color or price.
Check your eyes first, choose the type that suits your lifestyle, and make sure of hydration and oxygen permeability.
Comfort is not a luxury; it is what gives you a safe daily experience that prevents pain, allergies, and complications.
