Fun Facts About Contact Lenses

No.1 Do color contact lenses cause vision loss?

Wearing color contact lenses does not directly cause vision loss when they are properly prescribed, correctly fitted, and used according to professional guidance.

Changes in vision can occur for many reasons, including eye fatigue, prolonged near work, or uncorrected refractive changes, and are not solely related to contact lens use.

a. Eye strain and prolonged visual load

Extended screen time, long periods of near-focus work, or insufficient visual breaks may lead to eye fatigue. Over time, this can contribute to temporary visual discomfort.
These factors are related to general eye use habits and apply to both contact lens wearers and non-wearers.

b. Eye hygiene and lens care

Poor eye hygiene, such as touching the eyes with unclean hands, can increase the risk of eye irritation or infection.
For contact lens wearers, following proper hygiene, cleaning routines, and replacement schedules is essential.
Lenses should only be worn after professional assessment and fitting, and usage should comply with the recommendations provided by an eye care professional.

c. Changes in prescription

If refractive error changes over time, continuing to wear lenses with an outdated prescription may cause visual discomfort or reduced clarity.
Regular eye examinations help ensure that lenses remain appropriate for your current vision needs.

In summary:
Maintaining healthy eye habits, taking regular visual breaks, and attending routine eye exams are recommended for everyone—whether or not contact lenses are worn.

No.2 Why does vision sometimes become blurry when wearing contact lenses?

Blurry vision while wearing contact lenses may be related to several common factors:

a. Lens surface contamination
Cosmetic products or environmental particles may adhere to the lens surface, reducing clarity. If this occurs, lenses should be removed and properly cleaned before reuse.

b. Prescription mismatch
If your vision has changed, lenses that no longer match your prescription may cause blurred vision.

c. Lens deposits over time
During wear, normal tear components such as proteins or lipids can accumulate on lenses, which may affect visual quality. This is why appropriate cleaning and timely replacement are important.

For reusable lenses:

a. Clean and rinse lenses before and after each use

b. Replace lens solution every time

c. When lenses are stored, refresh the solution regularly according to product instructions

No.3 How can I assess whether my eyes are healthy?

The absence of discomfort does not necessarily indicate optimal eye health.
A comprehensive eye examination by a qualified eye care professional is the most reliable way to assess eye condition.

a. First-time contact lens users should undergo a full eye exam to confirm suitability.

b. Existing contact lens wearers are advised to have periodic check-ups and ensure lenses are worn only when eyes feel comfortable and healthy.

Situations where contact lens wear is generally not recommended

Contact lenses may not be suitable during certain conditions, including:

a. During systemic illness such as fever

b. When eyes feel significantly dry, irritated, or fatigued

c. During swimming or bathing

d. In environments with excessive dust, wind, or smoke

e. When adequate hygiene cannot be ensured

Always follow the advice of your eye care professional regarding lens use.

Seasonal reminder ☀️

Warmer weather may increase eye dryness or sensitivity.

a. Limit wearing time according to personal comfort and professional guidance

b. High temperatures and dry environments may increase dryness or irritation

c. Air-conditioned spaces can reduce humidity and increase tear evaporation; take visual breaks and blink regularly

If discomfort occurs, discontinue lens wear and consult an eye care professional.
