Contact contacts could be a nightmare for those who have dry eyes. Inside a healthy eye, a skinny layer of tears always forms within contact. If the layer gets dry, the lens begins feeling like sand. Is that this the inevitable cost you spend for that ease of contact contacts, or what is the better alternative?
Do contact contacts cause my eyes to dry?
You will find several causes for eye dryness. To begin with, many people simply produce less tears than the others, or their chemical composition of the tears isn't sufficient. The quantity of tears created usually decreases as we grow older.
Another cause is environment - should you operate in an overheated or air-conditioned room, of if you're uncovered to smoke, dust or wind, your vision will feel dry. Dry eyes will also be an issue for many computer customers. People often blink less when focusing on the pc and blinking is important for wetting your vision.
Finally, some contact contacts may also lead to dry eye syndrome. Most soft contact contacts are manufactured from polymers and water - sometimes as much as 70% water. While it's this moist, the lens feels comfortable inside your eye however the water disappears in the lens because the day progresses. Therefore the lens soaks up water out of your tears, departing you with dry-feeling eyes. In most cases, the greater water the lens consists of, the greater prone it's to get rid of its moisture.
Soft contacts that will help with dry eyes
Since dry eyes is really a serious issue for a lot of contact users, lens producers are continually trying to produce contacts which will be comfy for those who have dry eyes.
One of the ways would be to lessen the water content from the lens. Modern plastic hydrogel contacts are just about 30% water - a smaller amount compared to 50-60% of traditional contacts. Also, the brand new polymers utilized in contact contacts assist the lens to remain moist.
Of all the contacts developed for those who have dry eyes, Acuvue Oasis and Proclear Compatibles get the best reviews from users.
Acuvue Oasis, by Manley and Manley, is particularly developed for those who work or reside in dry conditions. It consists of high-quality polymer senofilcon A and consists of a unique rewetting agent - Hydraclear Plus - which makes the lens feel moist even when your vision don't produce enough tears. Acuvue Oasis is really a daily put on contact (you need to remove it during the night), and it ought to be changed every two days.
Proclear Compatibles, by Cooper Vision, is made of omafilcon A, that has shown high on-eye bloating, throughout studies. Also, Proclear uses the newest technology of biocompability. The lens consists of PC (phosphorylcholine) - an ingredient that happens naturally in human cells. It prevents the body from perceiving contact like a foreign object inside your eye and seeking to reject it. Consequently, Proclear Compatibles feel moist and smooth inside your eye and do not cause lack of fluids. Proclear are monthly disposable contact contacts.
RGP contacts for those who have dry eyes
Some doctors recommend their sufferers with dry eyes to change to Rigid Gas Permeable (RGP) contact contacts. This is because an RGP lens is made of polymeric materials and do not contain water. So water will not evaporate from the top of lens, just like soft contacts. Thus one reason for dry eyes is illuminated.
However, RGP contacts may present other issues for those who have dry eyes. Because the lens is rigid, it may irritate your skills if you will find insufficient tears under it. A rigid lens inside a dry eye feels much worse than the usual soft one.
For those who have dry eyes as well as your current contact contacts don't feel too comfortable, it's not necessary to accept the discomfort. Request your physician when the contacts we suggested would meet your needs.
