How to wear contact lenses safely PTP

Contact lenses are convenient tools that improve vision for people with myopia and enhance personal style, allowing for a fashionable look without wearing glasses. However, it&#8217;s crucial not to overlook the safety and potential risks associated with their use.

<h2>What should you know before wearing contact lenses ?</h2>
<ol>
<li>Choose the right contact lenses: Ensure the lenses are suitable for your eyes. Have an eye exam to confirm that you can wear contact lenses, and choose the appropriate material and lifespan. A contact lens fitting will help determine if the size matches the curvature of your cornea—not too loose or tight.
<ul>
<li>Rigid gas permeable lenses: Made from hard plastic, these can be uncomfortable initially but last up to 3 years. They are durable and easier to care for than soft lenses, and they can correct some astigmatism. However, they are used less frequently now.</li>
<li>Soft lenses: These are the most popular type, made from plastic that retains water, making them soft and flexible. They allow good oxygen flow to the eyes, providing comfort but have a shorter lifespan of about 1-2 years. It&#8217;s essential to maintain cleanliness to prevent infections and allergies.</li>
</ul>
</li>
<li>Learn proper insertion and removal techniques: Avoid wearing contact lenses for too long. Remove them when you get home to allow your eyes to receive adequate moisture and oxygen. Always wash your hands with soap or hand sanitizer before handling lenses, and keep your nails short. Do not wear contact lenses while sleeping, swimming, or diving.</li>
<li>Cleaning your contact lenses: Use a specific contact lens solution for cleaning; do not use saline solution, as it does not have antibacterial properties. Store the lenses in a dry case and replace the case at least every three months.</li>
</ol>
&nbsp;
<h2>Warning signs: When to stop wearing contact lenses</h2>
<ul>
<li>Excessive dryness: You can use artificial tears to add moisture, but if dryness persists or worsens, stop wearing the lenses and consult an eye doctor.</li>
<li>Redness or irritation: Symptoms like sticky discharge or protein buildup on the lenses may indicate corneal or conjunctival inflammation.</li>
<li>Swelling: If you notice bumps on the inner eyelid or small spots on the cornea, this may indicate inflammation caused by dry eyes or improper lens care.</li>
</ul>
&nbsp;
<h2>How to choose safe contact lenses</h2>
<ul>
<li>Check the expiration date: Always verify the expiration date on the packaging.</li>
<li>Look for FDA approval: Ensure the product has the appropriate regulatory approval (e.g., FDA, CE mark).</li>
<li>Review product information: Pay attention to the brand name and materials used to make the lenses.</li>
<li>Check your prescription: Ensure the lenses match your vision prescription.</li>
<li>Lens Size: The diameter should typically be between 14-15 mm, ensuring it is not too large.</li>
<li>Curvature: The lens curvature should match your cornea&#8217;s shape for optimal comfort and fit.</li>
</ul>
