Diving with glasses or diving with contact lenses? That is the question that divers with impaired vision are looking for to answer.
Using glasses or contact lenses to correct our vision is compatible with diving unless our doctor expressly contraindicates it. However, many of those with some loss of vision, do not know their real options to improve it underwater. As you know, water increases the size of things we see underwater, and sometimes that is enough to dive comfortably. However, if a diver is unable to read his/her underwater pressure gauge or to see his/her dive buddy’s hand signals, they should consider correcting their vision.
In this article, we will see the options we have for diving with glasses or diving with contact lenses, so you can choose the option that best suits your needs.
Diving With Glasses.
Who doesn’t remember Hugh Grant in his movie “Nothing Hill” going to the cinema with his diving glasses? To be honest, diving with glasses are a very widespread, and recommended option.
There are several options for diving with glasses. There are scuba masks with standard corrective lenses. They are ideal for the most common vision problems. You can choose to attach the corrected lenses to the tempered glass lenses of the mask or to opt for glasses with a fully customized prescription and may even include bifocals.
Diving with glasses’ advantages:
– you will have good vision during the dive;
– you will have long time span diving glasses because of they are not-scratchable and very resistant material;
– as you can purchase the lenses separate from the mask, you can change the prescription lenses only, and not the whole mask.
Diving with glasses’ disadvantages:
– prescription lenses have an extra cost, sometimes high, depending on graduation;
– it is convenient to have a spare mask in case you lose or damage your usual one.
Diving With Contact Lenses.
Diver’s Alert Network (DAN) recommends choosing soft contact lenses for those who prefer diving with contact lenses. As you know, there are different types of lenses. There are hard contacts and soft contacts. Soft contact lenses allow gas exchange, but hard ones do not. In this case, a diver could have blurry vision at the end of the dive. Let’s explain!
Nitrogen escapes from your eyes when you ascend. However, hard contact lenses do not allow this, and nitrogen bubbles remain between the contact lenses and the eye. In contrast, soft contact lenses let the gas out normally. On the other hand, hard contact lenses have less suction than soft ones, and it makes them easier to lose.
Another advice: close your eyes when you flood your mask or you could lose your contact lenses.
Diving with contact lenses advantages:
– it is a comfortable and fast option;
– you will be able to see properly in and out of the water;
– you do not need any extra investment. You will use your daily contact lenses.
Diving with contact lenses disadvantages:
– contact lenses dry out during diving because the blinking frequency decreases;
– it is advisable to use moisturizing drops before diving;
– you can lose the contact lenses;
– they can move into the eye due to pressure, losing visibility;
– Contacts can increase the risk of eye infection.
