How to Select Prescription Swim Goggles

When you need prescription glass to get around in your everday life, the idea of jumping in water either blind or blurry can be very intimidating!

The good news is that getting a quality pair of prescription swim goggles that come close to matching your glasses is now quick and easy.

Lenses

The goggles lenses are premade with spherical correction in differing strengths, also known as diopters.   The strength increments by 0.5 at a time, so they are not as precise as your regular custom ground eyeglass lenses.  However, for use in the pool, lake, or ocean they are perfectly fine.  They are also available NOW and at a fraction of the price of a custom pair made at your local optician.

Most people needing glasses are myopic (negative diopter), and are the most commonly available.   We carry them from -1.5 down to -7 in half increments, and then in full strengths down to -10.   

Aquagoggles also carries Positive + lenses for those of you with hyperopia.   Coming in full strengths only, from +2 to +6.  An easy way to check if these lenses will help you is to check out some off the shelf reading glasses at the pharmacy.

Figuring Out Your Lens Strength

Commonly the most confusing and stress inducing part of the process is figuring out what lenses will most closely match your current prescription.  We can usually help you out if have difficulty with following the steps below, or you can contact your eye doctor.

First, get your most current prescription numbers.  The important ones are for Sphere (Sph) and Cylinder (Cyl).

Sphere is the amount of correction needed to correct for the weakness in your diopter.  Cylinder is the degree of astimatism.  Or, which does your eye more closesly resemble?  A Football or a Soccer ball?

Enter your numbers in the Lens calculator below, and always round down to determine which lens strength would be best for you.  Ie, -4.875 would round down to -4.5

Enter the Sphere and Cylinder values from your prescription to determine which diopter strength would best suit you. Be sure to select + or - for each and enter all four values.
*This measurement is only a suggestion. It is best to confirm your diopter strength with your optometrist.

Choosing the right model

V2- Swim Goggles on vacation

Once you’ve determined you lens strength needs, it’s time to choose the goggles that are right for you.  If your numbers came out negative -, then our V2- prescription swim goggles are the ones for you.

If they came out positive +, then our V2+ (Blue) goggles are best.

When trying on your goggles for the first time, take the time to adjust their fit first and foremost.  Change the nosepiece as needed to fit your face, then adjust the strap for a snug fit.

Both styles as well as more info about our prescription swim goggles can be found here.

We’ve come a long way with our prescription swim goggles since 2001.  We’ve made changes to the lenses, better attachment types for the seal and nose piece.   We want a better fit so more people can see in the water.

We are always looking at ways to make them better, so let us know if you have any suggestions.

Swimming and the Eye

Swimming and The Eye

 

A shared communal body of water is a beautiful thing. If you’re wondering how swimming affects your eyes and what you can do to protect them, you’re in the right place. Stinging, burning, redness, and dry eyes are all common afflictions of swimmers getting in and out of the pool– and what’s more, it’s not just chlorine that’s causing all the commotion. The Center for Disease Control and Prevention’s annual swimming account reports that the smell of chlorine is actually the buildup of chemicals in combination with sweat, urine, and fecal matter from swimmers’ bodies. This wonderful concoction that ails the eyes is actually a chemical called chloramine.

 

Before the Pool

If you find yourself questioning those pesky mandatory shower stalls at the pool side, don’t worry, you’re not alone. However, showering before swimming is one of the most effective and only ways to prevent perspiration, urine, fecal matter, and bacteria from entering the water.

 

Keep in mind, encouraging others to shower before swimming not only protects the wellbeing of other swimmers, but also your personal hygiene. Sweat, dirt, lotions, oils, and bodily fluids are just a few components of the collective bathtub you’re about to enter. Feces and urine go hand in hand with public pools, kind of like peanut butter and jelly but not delicious at all. So, make sure to take a shower with soap and water before entering the pool to reduce any bacterial residue in both skin and hair.

 

Wearing Protective Eyewear

Chemicals can cause reactions on the exterior and edges of your eyes resulting in redness, itchiness, and watery eyes. Exposure to harmful chemicals and bacteria washes away and disrupts the tear film, a thin multi-layer of water, proteins, and lipids on the surface of the eyes. When this occurs, the protective layer is no longer able to function. Rather than keep eyes moist and clean, chemicals cause water to evaporate from the tear film and in turn, the eyes become dry, uncomfortable, and most importantly, exposed. Sensitivity to chlorine can also cause chemical conjunctivitis, a toxic pinkeye that that results in inflamed and irritated eyes.

 

Well-equipped with a pair of swimming goggles can keep harmful pool chemicals out of your eyes as well as keep those tear films healthy and lubricated. Wearing protective eyewear such as goggles or sunglasses when exposed to these environments can also prevent infection. On the other hand, contact lenses are not a form of protective eye wear. Water is the perfect medium for bacteria to thrive so it’s best to avoid wearing contacts altogether when entering a pool, hot-tub, beach, ocean, or participating in any water- activity.

 

After the Pool

Infections such as conjunctivitis can arise if any bacteria transfer out of the pool and into your eye. Washing your face with eyes closed can help wash away any chemicals from your outer lids and lashes. Showering with soap and water washes away any bacteria and germs on your body.

 

People who swim competitively or often develop dry eye as their tear production diminishes resulting in blurry vision. Staying hydrated is important for keeping eyes comfortable in the hot sun so be mindful of your hydration levels. Artificial tears as well as any lubricating eye drops can also relieve irritated eyes before and after swimming.

 

Preparation is the Key to Success

 

There’s nothing better than hanging by the water on a hot summer day to cool down. There’s also nothing worse than waking up with pink-eye the next morning due to exposing your eyes to harmful bacteria. To minimize risk and exposure to toxic microorganisms, wearing protective eyewear such as swimming goggles can prevent any sight threatening contaminations. Contact lenses in the pool, ocean, hot-tub, lake, or any exposure to a water environment can also be hazardous. Spread awareness in your community and maximize your health and hygiene simply by wearing goggles and taking a shower before and after swimming.
