Demystifying Dive Mask Prescriptions: What You Need to Know

Hey there, fellow ocean enthusiasts! Are you gearing up for your next underwater adventure but feeling a bit confused about dive mask prescriptions? Don't worry; we've got you covered! At Oceans Optics, we understand the importance of clarity beneath the surface, and that includes ensuring you have the right prescription dive mask for your needs.


Let's dive right in and demystify everything you need to know about dive mask prescriptions, from understanding different types of prescriptions to choosing the best lens materials for optimal underwater vision.


Understanding Dive Mask Prescriptions


First things first, let's talk about the different types of dive mask prescriptions available. Whether you're nearsighted, farsighted, or need bifocals, there's a prescription dive mask option for you.


Single Vision: These are perfect for divers with a single vision prescription, whether it's for nearsightedness or farsightedness. They provide clear vision underwater without the need for reading glasses.


Bifocal: If you require both distance and near correction, bifocal dive masks are the way to go. They feature a small magnifying lens at the bottom of the mask for reading gauges or dive computers while maintaining clear distance vision.


Lens Materials and Coatings: When it comes to lens materials, tempered glass is the gold standard for prescription dive masks. It offers superior clarity, durability, and scratch resistance, ensuring optimal vision underwater. For snorkeling, resin plastic lenses are acceptable, but we always recommend tempered glass for diving.


Eye Exam Tips for Divers


Now, you might be wondering how to determine the right prescription for your dive mask. Here are a few tips to help you navigate the process:


Know Your Prescription: Understanding your prescription is the first step. If you're unsure, consult with an eye care professional to determine your exact prescription needs.


Consider Magnification: Underwater magnification can affect your vision. We recommend subtracting 50 from your prescription degree to account for this magnification effect.


Astigmatism Consideration: If you have astigmatism, calculating the exact prescription can be a bit tricky. Our formula, which involves dividing the astigmatism by 2 and adding it to the degree-50, can help you find the right prescription.Β 

Example prescription =Β  200Β° with 100Β° astigmatism. Let’s start by dividing astigmatism by 2. Now we have 50Β°astigmatism. Ok lets now check the degree we will need to cancel out the magnification. 200Β°- 50 = 150Β°

Excellent, now we can add them together.Β 

150Β°+50Β°=200Β°


Choosing the Right Dive Mask Prescription


When selecting your prescription dive mask, it's essential to consider not only your vision needs but also the quality of the lens materials and coatings. Opt for tempered glass lenses for the clearest vision and maximum durability, ensuring your underwater adventures are as crystal clear as can be.
