Want to have a pair of eyes brimming with charm and brightness? Eyes optical
are the windows of soul; furthermore they are arms to show our enchantment. Eyes need to be tended carefully just like flowers. Only healthy eyes are really beautiful. What can we do to moisturize our eyes that are trapped by fluorescent lights, air-conditioned rooms, and foul atmosphere and contact lens as well?
Oxygen and sunshine are the fundamental material conditions for creatures to live. Eyes, especially cornea without oxygen transported by blood-vessels, need to breathe in oxygen. First of all, take your eyes to the places with plenty oxygen. No matter how busy you are and how many dinners you have to go, if you treasure your eye, then give them plenty oxygen and sunshine. Once every day in the meadow or at the roof garden of the company building, just relax your eyes by looking far; once each week, go angling in the suburb or camping in the mountain to take more green views in your eyes.
The eyes of those who wear contact lenses are usually dry, itchy or inflamed like rabbits' eyes. What can they do to make their eyes more clear and bright? Let's start with cornea. It does not have blood vessel whereby to get access to oxygen supply, so the water molecule contained in contact lens has to play to role of oxygen supplier to eyes. Water molecules in the common contact ray ban
lenses are the major carriers of oxygen. It depends on the oxygen dissolved by water molecules to maintain the ordinary activity of corneal cells. As a result, the high water content lens keeps absorbing water from tears,which, when reduced, causes dryness to the eyes or some blood. Eyes need water to moisturize so to preserve moisture is very important. The ordinary run-eye drops almost belong to nutritional eye drops. They are mainly artificial tears functioning as lubricant, instead of aiming at particular treatment.
There are many kinds of eye-moisten drops on the market nowadays. They can be generally divided into two catalogues: one is water fluid which is comparatively thin and for people with light symptoms. The other is gel-like which has high density and high water-content that suitable for people with severe dry symptom. To the discomfortableness after long time working, eye-moisten drops could relief the symptoms of dry and tiredness in eyes.
But many eye-moisten drops ray ban sunglasses
on market contain antiseptic which could stimulate eyes, do harm to cornea and destroy the stability of lacrimal film. Those drops could not relief the symptoms but even aggravate the discomfortableness of eyes and result in organic injure; so, it is not appropriate for long-term use. Not use run-eye drops more than 4 times a day and you had better use it under the guidelines of doctors. For the health of eyes, the market launches new lenses of high oxygen permeability. Innovative "silicone hydrogel" material, with unique dual-channel structure, improves its oxygen transparency rate 5-6 times of the ordinary. The passage of water ion keeps the lens moist, while the passage of oxygen ion provides super high oxygen penetration, to ensure the continuous supply of water and oxygen to eyeballs. Don't depend on water molecules alone. Let cornea breathe in oxygen freely from the fundamental so as to avoid problems such as inflammations resulting from cornea's lack of oxygen.
