Reusing masks safely… a simple guide

March 31, 2020

Based on advice from Dr. Peter Tsai, the inventor of the major filtering component in the impossible-to-obtain N95 masks, the following is a guideline for reusing masks of any type… N95, surgical, or DIY:

Leave your mask in dry atmosphere air for 3-4 days to dry it out. COVID-19 needs a host to survive–it can survive on a metal surface for up to 48 hours, on plastic for 72 hours, and on cardboard for 24 hours. When the respirator is dry in 3-4 days, the virus will not have survived.

So… first method for reusing masks:

Take 4 masks, and number them (#1-4).
On day 1, use mask #1, then let it dry it out for 3-4 days.
On day 2, use mask #2, then let it dry out for 3-4 days.
Same for day 3, and day 4…

You can also sterilize the N95 mask by hanging it in the oven (without contacting metal) at 70C (158F) for 30 minutes-it is reported that COVID-19 cannot survive at 65C (149F) for 30 minutes. If you’re not sure about how accurate your oven temperature is, use a small oven thermometer. Amazon:

Use a wood clip to hang the respirator in the kitchen oven to do the sterilization.

Tidelands Health gets “overwhelming” support, as 2,000 volunteers offer to sew crucial medical masks

March 30, 2020

Tidelands nursing chief Pam Maxwell says the hospital has thousands of N95 masks, which are crucial to medical workers in the fight against COVID-19, but there’s one problem.

“It’s just that the straps that hold the mask on your head are very, very brittle,” said Maxwell.

Tidelands asked for help sewing new straps on the N95 masks and they definitely got it. The health care provider says more than 2,000 people have volunteered to sew the masks.

The big mistake in the U.S. and Europe … is that people aren’t wearing masks

March 30, 2020

“The big mistake in the U.S. and Europe, in my opinion, is that people aren’t wearing masks. This virus is transmitted by droplets and close contact. Droplets play a very important role—you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth. Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others.” George Gao , head of the Chinese Center for Disease Control and Prevention.

Avoid online contact lens “switches”.

July 29, 2019

Most online contact lens suppliers just want to ship you the lenses your doctor actually prescribed, but Hubble wants to switch you to a lens your doctor most likely did NOT prescribe and has never seen on your eyes. Not a recipe for success. Talk to your eye doctor at Coastal Eye Group about the best way to fit and purchase lenses for long term eye health and great vision.

Monovision is a wonderful way to avoid the need for glasses... but certainly caution needs to be taken in visually critical situations like driving. If you do not feel totally confident and comfortable with driving with monovision correction, glasses can be worn over your eyes to provide best corrected vision at distance in each eye. Talk to your eye doctor at Coastal Eye Group for more information and options.

Blue Light and Supplements Continue to be Hot Topics

July 23, 2019

Blocking blue light and arming the retinal with sufficient nutrients to combat the stresses inherent in our modern society continue to be publicly debated. So many of these “studies” come from companies that stand to make a lot of money if these various products are popular in the marketplace. Some quoted here are just that. It doesn’t mean what they say is untrue (or true). It’s certainly not inappropriate to print these sort of articles out and ask your doctor at Coastal Eye Group about them.

Can cataracts alter one’s color perception? Absolutely. Many of our cataract surgery patients at Coastal Eye Group are surprised at how colors shift and become brighter after surgery. Patients expect their vision to be sharper and less fuzzy, but the change in color is unexpected.

Eyes feel gritty? Sandy? Burn? You may very well have Blepharitis, one of the common conditions we deal with every day at Coastal Eye Group. Blepharitis is a chronic condition and tends to really never go away without intervention. View the overview video below to learn more.

Lid scrubs are a mainstay of dealing with Blepharitis over the long haul. Baby shampoo has been a mainstay of treatment for decades, but newer pads and foam cleaners may do a better job. Regardless, significant cases often have to be “jumpstarted” with a short regiment of antibiotic/steroid drops. If you have symptoms of Blepharitis, make an appoint with one of our doctors at Coastal Eye Group and find out just exactly what is going on, and what needs to be done.
