Tips and tricks to care for contact lenses
As an optometrist with years of experience, I've seen it all when it comes to contact lens wear. Patients often come in with complications that are entirely preventable with proper care. It's not just about following the basics; it’s about understanding why those basics matter. This isn’t a quick “do this, don’t do that” list; it's a deep dive into keeping your eyes healthy and your vision clear while enjoying the freedom of contact lenses. We’ll cover everything from daily habits to troubleshooting common issues, designed for both new and experienced lens wearers.
What’s the biggest mistake people make with contact lenses?
Hands down, it’s not consistently following the cleaning and replacement schedule. It's easy to stretch things a little – “Oh, I only wore them for a few hours, I can probably get away with another day.” That mindset is a recipe for problems. Contact lenses aren’t just plastic discs; they’re medical devices. They interact directly with the surface of your eye, and deposits – proteins, lipids, calcium – build up with wear. These deposits reduce oxygen permeability, increase the risk of infection, and cause discomfort. Think of it like this: even a thin film on a lens drastically impacts light transmission and clarity. A buildup over several days or weeks? Significantly worse.
Different lens materials and modalities (daily disposables, two-weeklies, monthlies) have different tolerances. Daily disposables are the gold standard for hygiene because you simply discard them, eliminating the need for cleaning. But even with reusable lenses, adhering to the recommended replacement schedule is crucial. A monthly lens must be replaced monthly, not 35 days later. Two-week lenses, every two weeks. It's not arbitrary.
How should I really clean my contact lenses?
Cleaning isn’t just about swishing with solution. It’s a multi-step process. Here's what I recommend:
- Wash your hands thoroughly. This isn't just a quick rinse. Use soap and water, scrub for at least 20 seconds (think of singing “Happy Birthday” twice), and dry with a lint-free towel. Residue from hand lotions, makeup, or even dust can transfer to your lenses.
- Rub and rinse. Even if you use a “no-rub” solution, I advise a gentle rub. This physically removes debris that the solution alone might not. Use your fingertip, not your fingernail. Rinse thoroughly with the solution – a few drops isn’t enough.
- Case care is essential. Your lens case is a breeding ground for bacteria. Empty the case after each use, rinse with fresh solution (never tap water!), and air dry upside down. Replace your lens case at least every three months. Yes, even if it looks clean. The plastic degrades and harbors contaminants.
- Solution matters. Don't mix solutions. Don't top off old solution. Use fresh solution every time. There are different types of solutions – multipurpose, hydrogen peroxide, etc. – and your optometrist recommended one specifically for your lens type and eye health.
Many people don't realize the importance of the rinse step. Residual cleaning solution can irritate the eye. A good practice is to insert the lens while it's still wet with fresh solution.
I often skip cleaning when I’m tired – is that okay?
No. Seriously. Just don’t. Sleeping in lenses, even for a short nap, dramatically increases the risk of infection. The eye needs oxygen, and a closed eyelid combined with a lens significantly reduces oxygen flow. While some lenses are approved for extended wear, that's after a thorough evaluation by your optometrist to ensure your eyes are suitable. Self-treating extended wear is extremely dangerous. If you occasionally fall asleep in your lenses, remove them immediately upon waking and monitor for redness, pain, or blurred vision. If any of those symptoms occur, contact your optometrist.
What about different types of lenses – do the care instructions change?
Absolutely. Here's a breakdown:
- Daily Disposables: The easiest. Wear once and discard. No cleaning required.
- Two-Weekly/Monthly Lenses: Follow the cleaning routine outlined above religiously. Pay close attention to the recommended solution and replacement schedule.
- Rigid Gas Permeable (RGP) Lenses: These require a specific cleaning solution designed for RGP lenses. Rubbing and rinsing is especially important, as deposits build up more quickly on these materials. Also, RGP lenses require regular polishing to maintain their surface quality.
- Toric Lenses (for astigmatism): These are often made of softer materials but still require diligent cleaning. Be gentle, as it's easy to distort the lens shape if you handle them roughly.
- Multifocal Lenses: Similar care to standard soft lenses, but be mindful of keeping the lens oriented correctly on your eye.
My lenses sometimes feel dry – what can I do?
Dryness is a common complaint, especially in our climate here in Okotoks, Alberta, with its dry air and potential for wind. Several factors can contribute:
- Low Humidity: Use a humidifier, especially in the winter.
- Prolonged Screen Time: We blink less when staring at screens, leading to dry eyes. Practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
- Lens Material: Some materials retain moisture better than others. Discuss options with your optometrist.
- Rewetting Drops: Use artificial tears specifically designed for contact lens wearers. Avoid drops containing vasoconstrictors, as they can mask underlying problems.
If dryness persists, it could indicate an issue with lens fit or your tear film. Don't self-treat; schedule an exam.
How long can I realistically wear my lenses each day?
This varies based on the lens material, your individual tear production, and your daily activities. However, a general guideline is 8-10 hours. Anything beyond that significantly increases the risk of corneal hypoxia (oxygen deprivation). If you work long hours at a computer or in a dry environment, consider reducing your wear time or switching to daily disposables. Listen to your eyes! If they feel uncomfortable, remove the lenses.
What should I do if I think I have an eye infection?
Remove your lenses immediately. Do not continue to wear them. Symptoms of an eye infection include redness, pain, blurred vision, light sensitivity, and discharge. Contact your optometrist or, if it’s after hours, seek urgent medical attention. Do not attempt to self-treat. Early diagnosis and treatment are crucial to prevent serious complications.
Remember, proper contact lens care is an ongoing commitment. It's not a one-time lesson. Regular check-ups with your optometrist are vital to ensure your lenses fit properly and your eyes remain healthy.
