Contact Lenses for Sports: Improving Performance and Convenience
As an optometrist with years of experience fitting contact lenses, I often talk to athletes – from weekend warriors to serious competitors – about how lenses can enhance their game. It's not just about vision correction; it's about maximizing peripheral vision, comfort, and overall performance. This isn’t a one-size-fits-all conversation, though. There’s a lot to consider, and what works for one sport, or one person, won’t necessarily work for another. This article will cover the key factors, going beyond the usual "yes, contacts are good for sports" to give you practical guidance.
What are the benefits of contact lenses for athletes?
The most obvious benefit is unobstructed vision. Glasses, even sports frames, have frames that can obstruct peripheral vision. This is especially critical in sports requiring a wide field of view like hockey, basketball, soccer, or cycling. With contact lenses, you experience a wider, more natural visual field. But it goes deeper than that:
- No Fogging or Sliding: Sweat, rain, or rapid temperature changes can cause glasses to fog up or slide down your nose at the worst possible moment. Contacts eliminate these issues.
- Improved Depth Perception: Contacts sit closer to the eye than glasses, which can improve depth perception, crucial for judging distances in sports like golf, baseball, or tennis.
- Protection from the Elements: While not a replacement for proper eye protection (more on that later!), contacts offer a small degree of protection from wind, dust, and debris.
- Enhanced Confidence: For some, simply feeling more secure and less self-conscious about their vision can improve performance.
Which types of contact lenses are best for sports?
Not all contact lenses are created equal, especially when it comes to sports. Here’s a breakdown of common types and their suitability:
- Daily Disposables: These are often the best option for most athletes. You wear them once and discard them, minimizing the risk of protein buildup and infection. They’re great for infrequent sports participation or for those who don't want the hassle of cleaning. Cost-wise, they’re a bit more expensive upfront (around $40-$60 CAD per month, depending on your prescription and brand), but the convenience and reduced risk often outweigh the cost.
- Two-Weekly Lenses: A good compromise between cost and convenience. These require cleaning and storage, but they’re less expensive than dailies (around $25-$45 CAD per month). They’re suitable for athletes who participate in sports consistently.
- Monthly Lenses: The most economical option (around $20-$35 CAD per month), but they require the most diligent cleaning and care. Not ideal for those who are prone to dry eyes or participate in dusty/dirty environments.
- Silicone Hydrogel Lenses: These materials allow more oxygen to reach the cornea, reducing dryness and discomfort, especially during prolonged wear. I strongly recommend silicone hydrogel lenses for almost all athletes, regardless of the wear schedule.
- Rigid Gas Permeable (RGP) Lenses: While offering excellent clarity, RGPs aren't typically the first choice for most sports due to potential discomfort and a smaller visual field compared to soft lenses. However, for certain sports requiring exceptional visual acuity (like shooting), they can be considered.
What about specific sports? Are some lenses better suited for certain activities?
Absolutely. Here’s how the considerations change depending on the sport:
- High-Impact Sports (Hockey, Basketball, Lacrosse): Eye safety is paramount. While contact lenses don't prevent direct impact injuries, they can offer a degree of protection compared to glasses shattering. However, always wear properly fitted sports goggles or a full-face shield over your contacts. Daily disposable lenses are highly recommended due to the increased risk of debris getting under the lens.
- Water Sports (Swimming, Surfing, Water Polo): This is tricky. It's generally not recommended to wear contacts directly in the water. Even with goggles, there’s a risk of waterborne pathogens causing serious infections (like Acanthamoeba keratitis – a rare but devastating corneal infection). If you absolutely must wear them, use daily disposables and immediately remove and disinfect them after exposure to water. Many athletes in Okotoks, Alberta, who enjoy water sports at nearby lakes, opt for glasses during those activities.
- Outdoor Sports (Cycling, Running, Golf): Dry eye is a common issue. Silicone hydrogel lenses are essential here, and consider lenses with high water content. Also, UV protection is important – ensure your lenses (or sports eyewear) block 100% of UVA and UVB rays.
- Dusty/Dirty Sports (Motocross, Volleyball): Daily disposable lenses are crucial to minimize debris buildup. Frequent lens replacement is key, even if you don't finish a full day's wear.
What are the risks of wearing contact lenses during sports?
While the benefits are significant, it's crucial to be aware of the risks:
- Corneal Abrasions: A scratch on the cornea can be caused by a foreign object getting under the lens or by the lens rubbing against the eye.
- Infections: As mentioned earlier, bacterial, fungal, or parasitic infections are a serious concern, especially with improper lens care or water exposure.
- Dry Eye: Prolonged wear or certain sports can exacerbate dry eye symptoms, leading to discomfort and blurred vision.
- Lens Dislodgement: Although rare, a lens can become dislodged during impact or vigorous activity.
What do most people not realize about contact lenses and sports?
A lot of people think any contact lens will do. That's simply not true. The fit is critical. A poorly fitted lens can cause discomfort, blurred vision, and increase the risk of complications. Also, many athletes don't realize the importance of proper cleaning and disinfection, even with daily disposables. While you discard the lens, your hands and the lens case still need to be clean to prevent contamination. Finally, some athletes assume that contacts replace the need for sports eyewear, which is a dangerous misconception. Contacts enhance vision, but they don't provide impact protection.
How often should I get my eyes checked if I wear contact lenses for sports?
I recommend a comprehensive eye exam, including a contact lens fit assessment, at least once a year, even if your prescription hasn’t changed. If you experience any redness, pain, blurred vision, or excessive tearing, see your optometrist immediately. Don't try to self-diagnose or treat eye problems.
The initial contact lens fitting process typically takes 60-90 minutes. We’ll assess your vision, measure your corneal curvature, evaluate your tear film, and try different lenses to find the best fit for your eyes and your sport. A follow-up appointment is usually scheduled 1-2 weeks later to ensure the lenses are comfortable and providing clear vision.
