How to choose the right prescription swim goggles for you？

What can people with diopter strength do if they want to see more clearly when swimming? The first possibility is to wear contact lenses under your swimming goggles, but this method requires that the goggles you choose have a good seal and do not leak, otherwise they can cause a series of eye risks. A better alternative is to wear prescription goggles, which are available from many brands such as Arena, Speedo, and they can also be found on platforms like Amazon and Walmart. But how do you choose the right goggles? Here are some tips for you.

Select the lenses:

Prescription swimming goggles come with ready-made lenses in different strengths. Although not as precise as the glasses you normally use, but they are perfectly adequate in the water. Prescription swimming goggles are most commonly used for nearsightedness, with a refractive intensity range of -1.5 to -10.0. There are also prescription goggles designed for farsightedness, but they are less common and used by fewer people.

Determine the right prescription strength:

The first step in choosing the right goggles for you is to make sure they match the strength of your current eye prescription. You can ask your doctor to help you choose the best ones for you, or you can follow these steps to help you make a determination:

1. Determine your current eye prescription.
2. If you have astigmatism, you will also need to determine the strength of your astigmatism.
3. Use the following formula to calculate the Calculate the strength ofthe diopter:

1/2 of the astigmatism strength + your current eye prescription = the final diopter strength.

4. The strength of the diopter should be rounded down. Tips: It isrecommended that the strength of the diopter be reduced by 100 degrees because refraction in the water and selection according to the usual prescription can lead to dizziness and discomfort when swimming in the water.

What should I do if the two eyes do not have the same diopter strength? 

No problem, you can buy two pairs of the same model prescription swim goggles and then just disassemble and reassemble them.
