Rapoport said that snap-on magnetic frames for your
Glasses are safe and convenient to wear. One upside to magnetic frames is that they typically do not use screws or hinges to attach to the primary frame—fixtures that could cause discomfort or irritation for the wearer.
But what about the magnets? Could they cause any problems?
“There is no evidence to suggest that they are not safe,” said Rapoport, adding that the magnetic frames “are safe to use as long as they are the right prescription.”
Laura Di Meglio, OD, instructor of Ophthalmology at the Johns Hopkins University School of Medicine, told Verywell that the magnets on the snap-on frame attachments do not pose a health risk to eyeglass wearers. The magnets used in the frames are small and only put a relatively weak magnetic field.
“There is really no concern with the magnetic factor of it because these magnets are pretty small in general and have no chance of causing any issues really at all,” said Di Meglio. “I’ve never heard or seen any issues with having magnets close to the eye or it causing any changes to structures or permanent effects on any cells in the eye.”
According to Di Meglio, magnetic frames could potentially cause a problem if a wearer got a foreign body made of
Metal in their eye—however, even then, Di Meglio said the chance of the tiny magnets causing issues is unlikely.
Do Eye Experts Recommend Snap-On Magnetic Frames?
While using snap-on magnetic frames are generally safe to use, experts say that whether or not you choose to wear them is a personal choice.
“If they are comfortable and you like the way they feel and look, then it’s definitely not harmful to wear them,” said Rapoport. “In the end, it’s a personal preference and less so a medical decision.”
Di Meglio said that there are some benefits to snap-on magnetic frames, including how easy and convenient they are to use, that they come in many different styles, colors, and patterns; and that they can be more affordable than purchasing more than one pair of glasses in different styles.
“They’re fun for people to get different looks out of one pair of glasses rather than having to buy multiple pairs,” said Di Meglio. “You can also get different shapes and colors which gives people a lot of diversity and freedom to change things up without having to spend money on getting multiple pairs.” 
What to Consider Before Trying Magnetic Frames ?
If you decide to use snap-on magnetic frames for your glasses, experts say there are a few tips to keep in mind:
Choose frames/glasses from reputable brands. Trusted brands follow safety regulations and industry standards. Buying from these brands will help make sure that you are getting a safe and quality product.
Check that the glasses and frames fit properly to your face. If your glasses and frames are too loose or tight, it can cause discomfort or irritation. You may also need more frequent adjustments and it could affect how clearly you can see through the lens.
Be gentle when putting on and removing frames. If you’re too aggressive when you put on or take off the frames, it can cause them to break or snap. Not being gentle with your glasses or frames can also cause them to crack or get flimsy over time.
