Contact lenses tend to leave eyes dry because they deprive eyes of their oxygen supply. People with dry eye syndrome find contact lenses exacerbating the dryness. The discomfort is usually characterized by dryness, difficulty blinking, itching, inflammation & inability of the cornea to hold the contact lens. As a result corneal abrasions & scarring may occur. Fortunately, there are several options available with contact lenses for eye dryness. Today, contacts are more comfortable than ever & progress continues.
Poly Hema Colored Contact Lenses VS Silicone Hydrogel Contacts
Today, colored contact lenses are made with biocompatible poly hema hydrophilic material that keeps eyes hydrated. These soft circle contacts are better than rigid contacts however, they do obstruct oxygen to some extent that may make it troublesome for patients with severe dryness of eyes to tolerate contacts. Silicone hydrogel lenses on the other hand are considered best colored contact lenses for people fighting with dry eyes. They are great for extended hours of wear and can be left in eyes for 30 days straight. Silicone hydrogel lenses allow more oxygen to enter your cornea that make them the best bet for people with dry eyes.
Silicone Hydrogel Colored Contact Lenses at a Glimpse
- Limits protein buildup that makes them safe to wear for extended wear
- Wettability is 2 times greater than standard soft contact lenses
- High oxygen transmission
- Less likely to cause corneal abrasions
What role does water content play?
Soft contact lenses are made from water loving plastic that hold some degree of water to stay moist and flexible. Though contact lenses with high percentage of water are more supple & comfortable to wear, they get dry more quickly. Soft contacts are available in varying level of water percentage from 38% to 70%.
Contact lenses with high water content when begin to get dry will draw water from the environment –eyes in this case. They also require more maintenance since you will have to check the contact lens chambers for the soaking solution when left in them during the days you are not wearing them. Unlike contacts with low water content, these contacts suck up the solution overnight they are soaked in.
Silicone hydrogel contacts are usually low in water & high in oxygen permeation that keep them wearable for dry eyes. Eyevelyn by Geolica are the only USFDA approved colored contact lenses made using silicone hydrogel technology. These contacts also offer UV blocking properties. You may also need rewetting drops or prescription eye drops in case you spend most of your time working at digital screens. Dryness can be managed using right type of contact lenses along with lubrication drops. Just don’t forget to talk to your eye doctor.
