Contact Lenses for Sports: Fit, Safety, and Performance Tips
As an optometrist with years of experience, I've seen firsthand how much of a game-changer the right eyewear can be for athletes. While glasses certainly have their place, contact lenses often provide a superior experience for many sports, offering unobstructed vision, improved peripheral awareness, and a secure fit. But simply switching to contacts isn’t enough. Getting it right – especially when it comes to sports – requires understanding the nuances of fit, material, care, and potential risks. This post will cover everything you need to know to make informed decisions.
What are the benefits of contact lenses for sports?
The advantages are clear for many. Glasses can shift during activity, restrict your field of vision, and, let’s be honest, are vulnerable to impact. Contact lenses move with your eye, providing a wider, clearer field of view, and eliminating the risk of frames breaking or digging in during intense activity. This is particularly important in sports requiring quick head movements or where peripheral vision is crucial – think basketball, hockey, soccer, or even cycling. However, it’s not a universal solution. Some individuals simply aren’t good candidates due to dry eyes, allergies, or other conditions, which we’ll touch on later.
What type of contact lenses are best for my sport?
Not all lenses are created equal. The ‘best’ lens depends heavily on the sport you play and your individual needs. Here's a breakdown:
- Daily Disposables: These are generally the safest option for most sports. You wear them once and discard them, minimizing protein buildup and the risk of infection. They're excellent for infrequent sports participation or if you’re prone to allergies. The cost per day is higher, roughly $1.50 to $3.00 per eye, but the convenience and hygiene benefits are significant.
- Two-Weekly or Monthly Lenses: More economical in the long run (around $30 - $60 per box), but require diligent cleaning and disinfection. They are suitable for consistent, regular sports practice but demand strict adherence to cleaning routines.
- Silicone Hydrogel vs. Hydrogel Lenses: Silicone hydrogel lenses allow more oxygen to reach the cornea, leading to healthier eyes, especially with extended wear. They're generally preferred for all-day wear and activities where lenses might be worn for longer periods. Hydrogel lenses are older technology; while still usable, they don’t breathe as well and can feel drier.
- Rigid Gas Permeable (RGP) Lenses: While less common for sports, RGPs offer exceptional clarity and durability. They're a good option for individuals with astigmatism or those who need a very precise correction, but require a longer adaptation period and are more fragile.
- Specialty Lenses: For very specific needs, such as corneal irregularities, scleral lenses may be considered. These are larger diameter lenses that vault over the cornea, providing exceptional comfort and vision, but are complex to fit and maintain.
What’s the deal with impact resistance? Are contact lenses safe during contact sports?
This is a critical question, and a common misconception. Contact lenses do not provide impact protection. They offer no shield against direct blows to the eye. In fact, a contact lens can actually increase the risk of injury in a direct impact scenario. Here’s why: the lens can trap debris and prevent it from being flushed away by tears, and the force of the impact can drive the lens into the cornea.
Always wear appropriate protective eyewear – safety glasses, goggles, or a face shield – during contact sports like hockey, basketball, lacrosse, or racquetball, even with contact lenses. The eyewear provides the necessary physical barrier. We often see patients in Okotoks and the surrounding Calgary area who mistakenly believe contacts alone are enough. They aren't.
How important is the fit? What should I look for?
Fit is paramount, even more so for sports. A poorly fitted lens can cause discomfort, blurry vision, and even corneal abrasion. Here’s what to consider:
- Base Curve: This matches the curvature of your cornea. Incorrect base curve leads to lens movement and discomfort.
- Diameter: The lens needs to be wide enough to cover the cornea without irritating the eyelids, but not so wide that it rubs.
- Lens Power: Accurate refraction is crucial. Even a slight error can affect performance and cause eye strain.
- Lens Material: As mentioned earlier, silicone hydrogel is generally preferred for oxygen permeability.
A professional fitting is non-negotiable. We use a variety of instruments to measure your corneal curvature, pupil size, and tear film characteristics to determine the best lens parameters for you. Don’t try to order lenses online without a valid prescription and fitting. You might save a few dollars upfront, but risk damaging your eyes.
What about dry eyes and contact lens wear during sports?
Dry eyes are a common issue, and sports can exacerbate them due to increased evaporation from wind and exertion. If you experience dryness, consider these strategies:
- Rewetting Drops: Use preservative-free artificial tears liberally throughout the day, especially before and after sports.
- Punctal Plugs: These tiny plugs inserted into your tear ducts help retain moisture.
- Lens Material: Choose a lens with a high water content or consider a silicone hydrogel material.
- Blinking Exercises: Consciously blink more frequently to lubricate your eyes.
- Humidifiers: Using a humidifier, particularly during winter months in Alberta, can help maintain moisture levels.
If dry eye is severe, contact lenses might not be a viable option. We can assess your tear film and recommend alternative solutions, such as glasses or refractive surgery.
Contact Lens Care: What do I need to know?
For reusable lenses, proper care is essential to prevent infection. Always:
- Wash your hands thoroughly with soap and water before handling lenses.
- Use a multi-purpose solution recommended by your optometrist. Don't use tap water or saliva!
- Clean and disinfect lenses after each use.
- Replace the lens case every 1-3 months. They can harbor bacteria.
- Never wear lenses past their expiration date.
Even with daily disposables, it’s crucial to practice good hygiene. Always handle lenses with clean hands and avoid contaminating the packaging.
When should I see an optometrist?
Schedule a comprehensive eye exam and contact lens fitting if:
- You’re new to contact lenses.
- Your prescription has changed.
- You experience any discomfort, redness, blurry vision, or pain while wearing contacts.
- You suspect you have an eye infection.
- You want to switch to a different type of lens.
Don't ignore any changes in your vision or eye health. Early detection and treatment can prevent serious complications.
Remember, choosing the right contact lenses for sports is about more than just vision correction. It's about safety, comfort, and performance. A thorough evaluation and proper fitting are essential to ensure you can enjoy your favorite activities with confidence.
