A contact lens is a synthetic lens positioned on the cornea, serving refractive, therapeutic, or diagnostic purposes. They are primarily used for correcting myopia (nearsightedness) and hypermetropia (farsightedness) and contemporary contact lenses cater to a broader range of needs. Specialized lenses now address conditions like astigmatism with toric lenses and presbyopia, expanding the scope of corrective options.
Understanding the importance of caution is crucial for individuals who wear contact lenses. In the upcoming points, we'll explore various aspects highlighting the need for careful practices. From maintaining hygiene to the impact of extended wear, each factor contributes to ensuring the safety and comfort of contact lens wearers. Let's look closely at these points to better understand why being careful is important for taking care of your eyes when you wear contact lenses.
Duration of Lens Wear
Adhere to your eye doctor's recommendations for replacing lenses, even if not worn daily. Disposable lenses, meant for one use, should be discarded after each wear to minimize the risk of eye infections associated with prolonged use or overnight wear.
Preparation Before Handling Lenses
Always wash hands before inserting or removing lenses, avoiding oily or heavily scented soaps. Dry hands thoroughly with a lint-free towel to prevent lenses from clinging. If using moisturizer, apply it after handling lenses to avoid residue.
Consistently start with the same eye to avoid confusion. Rinse lenses with the recommended solution, then use your index finger to place the lens on the iris. Gently release lids and blink.
Wash hands before removing lenses. For soft lenses, gently move the lens to the white of your eye and pinch it off. Gas-permeable lens removal involves pulling the skin near the eye corner, blinking, and allowing the lens to pop into your palm.
Cleaning and Storage
Choose a multipurpose solution for cleaning, rinsing, disinfecting, and storing lenses. Rubbing lenses during cleaning is recommended for effective cleansing. Hydrogen peroxide solutions require soaking lenses before reuse. Avoid tap water, as it may harbor microbes.
Avoid Water Contact
Never rinse lenses with tap water, wear them in the shower, or put them in your mouth. Microbes in water can lead to severe eye infections.
Lens Case Care
Regularly clean the lens case with a disinfecting solution, rinse nightly, wipe with a tissue, and air-dry to eliminate bacteria. Replace the case every three months or sooner.
Discomfort and Lens Removal
If lenses feel uncomfortable, remove and rinse them with rewetting drops. If discomfort persists, consult an eye doctor and refrain from wearing lenses with red or irritated eyes.
Teens and Lens Wear
Mature teens can wear lenses with proper care. Disposable lenses offer a convenient option, and fitting by an eye doctor ensures a perfect match.
Makeup Tips for Lens Wearers
Apply soft lenses before makeup and gas-permeable lenses after. Choose non-allergenic makeup and avoid metallic or glittery products. Replace eye makeup every three months.
Contact Lenses and Sports
Lenses are suitable for most sports, offering stability and unhindered vision. Avoid wearing lenses while swimming, especially in lakes, to prevent infections.
Maintain prescription glasses for breaks or situations where lenses can't be worn. Sunglasses, blocking 99% of UV light, are essential for eye protection.
Decorative and Cosmetic Lenses
Obtain decorative lenses from an eye doctor, as selling them without a prescription is illegal. Poorly fitting lenses may cause scratches or infections.
Digital Eye Strain
Reduce screen-induced eye strain by following the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. Use rewetting drops during screen time.
Consult an Eye Doctor
Prioritize an eye doctor consultation before considering contact lenses. Lenses vary in materials, shapes, and strengths, necessitating a precise fit tailored to individual eyes, even for online purchases.
