Vision clarity

Both high quality soft and RGP contact lenses provide good vision. However, studies have shown that properly fitted RGP lenses provide better vision. This is important for people who rely on their eyes in their jobs - truck drivers, pilots - and for certain sports, like shooting.

Also, many soft lens wearers report that their contacts feel funny in dark and their vision decreases. RGP don’t have this problem.

Eye health comparison

Two important factors determine how healthy a contact lens is for your eyes - oxygen permeability and resistance to protein build-up.

RGP lenses let through 2-4 times more oxygen than soft contact lens. Therefore risk of corneal inflammation is much lower. The only soft lenses that have oxygen permeability comparable to RGP lenses are silicon hydrogel contacts, like Focus Night and Day or Acuvue Advance

Soft lenses are more prone to protein build-up than RGP contacts. Of course, if you wear daily disposable soft lenses, this is not an issue. But if you use monthly or quarterly replacement lenses, by end of its life lens is covered with proteins no matter how carefully you clean it. RGP are made from totally different material - plainly said proteins and other secretions don’t stick to them.

When your hair goes grey it is due to fact that cells in hair follicles called “Melanocytes” no longer generate pigment, main one being melanin. The hair follicle loses all pigment over time and eventually goes white. The white hairs against your darker hair give effect of grey hair. As your hair is no longer as healthy as it use to be you need to consider treating it to prevent it from going brittle and lifeless.

The vital vitamins that your hair would need in this case is B12, and Omega 3’s. You can take these supplements as tablets or you can use a shampoo that contains these types of nutrients. There are many products on market that promise to treat Grey Hair or even take Gray Hair away. Beware as there are only a few that will actually be effective.
