## Can We Wear Spectacles While Scuba Diving?
**Introduction**
Scuba diving is an exhilarating water sport that allows us to explore the hidden depths of the ocean. However, for those who need vision correction, the question of whether spectacles can be worn while scuba diving arises. In this comprehensive guide, we will delve into the safety considerations, types of spectacles available, and tips for using spectacles while scuba diving.
### Safety Considerations
**1. Fitting:**
Scuba diving masks form a seal around the diver’s eyes and nose to prevent water from entering. Wearing spectacles can disrupt this seal, potentially causing water leakage and vision impairment. Therefore, it is crucial to ensure a snug fit between the mask and spectacles.
**2. Fogging:**
The temperature difference between the cold water and the warm air inside the mask can cause fogging. Spectacles may further contribute to fogging, especially if they are not treated with an anti-fog solution. This can significantly impair vision underwater.
**3. Pressure:**
Scuba divers experience increased water pressure with increasing depth. This pressure can cause the lenses of the spectacles to flex and distort, resulting in blurred vision.
## Types of Scuba Diving Spectacles
**1. Corrective Lenses:**
Prescription lenses can be inserted into a diving mask with the help of an optical laboratory. This option provides optimal vision correction and reduces the risk of vision distortion. However, it can be more expensive than other options.
**2. Insert Lenses:**
Insert lenses are pre-made corrective lenses that clip onto the inside of a diving mask. They are a more affordable alternative to corrective lenses and can be easily removed for surface use.
**3. Diopter Lenses:**
Diopter lenses are magnifying lenses that can be attached to the inside of a diving mask. They are less precise than corrective lenses but can provide some level of vision correction for nearsighted divers.
## Tips for Using Spectacles While Scuba Diving
**1. Choose a Mask with a Wide Field of View:**
A mask with a wide field of view will accommodate spectacles better and provide a wider range of underwater visibility.
**2. Use an Anti-Fog Solution:**
Treat your spectacles with an anti-fog solution to prevent fogging during the dive.
**3. Wear Contact Lenses:**
Contact lenses can be a more comfortable and convenient alternative to spectacles while scuba diving.
**4. Practice in a Pool:**
Before diving in open water, practice using spectacles in a swimming pool to get accustomed to the fit and vision distortion.
**5. Bring a Backup Mask:**
Always carry a backup diving mask in case of any issues with the primary mask.
**6. Consider Prescription Dive Masks:**
Prescription dive masks are specifically designed for divers who need vision correction. They provide clear vision and eliminate the need for spectacles or contact lenses.
### Conclusion
Wearing spectacles while scuba diving is possible with proper preparation and consideration of the safety implications. By choosing the right type of spectacles, adhering to the tips outlined above, and practicing in a controlled environment, divers with vision correction can enjoy the underwater world with clear vision and safety in mind.
