Eye inflammations can be the consequence of body resistance to contact lenses and allergies to constituents present in cosmetics, the little applicators used to apply them, and the chemical cleansers applied to take them off.
You may use contact lenses|Contact lenses are ordinarily used to correct refractive errors, alleviate recurring eye diseases, or to improve your looks (by changing eye colour, for example).
The contact lens is one of the few extraneous objects that get into intimate, prolonged contact with the sensitive tissues of your eye.
It is, technically speaking, a synthetic implant, similar to such synthetic devices as silicone breast implants, artificial heart valves, etc.
The contact lens has the potential to induce eye health issues because for as long as it is in your eye, it challenges the normal operation and the protective mechanisms.
Dry eye can develop from contact lens wear for varied causes.
Problems with Long-Term Wear Over a long period, having contact lenses in the eye can dull the nerves of the cornea.
Decreased corneal nerve reactions can lead to inadequate tear production and lesser blinking frequency.
Infrequent blinking can compromise the eye, as lubrication is not evenly-spread all over the eye.
Ultimately, this can give rise to a full-fledged dry eye syndrome.
A contact lens can perform its target function only if the quality of your tears is good enough to support the lens properly.
Tears deficient in the watery tear layer or that vaporise too quickly do not enable the contact lens from refracting light properly.
The eye will get very painful from the strain of uncorrected vision.
Problems with the Lens Itself The lens bears down on your eye's cornea.
The relentless pressure can distort the curvature of the cornea and pack tight its fibrous tissues (called the stroma) into a thinner layer.
The mechanical damage can raise the temperature of the eyelids and the cornea, rapidly causing inflammation.
The fabrication of contact lenses requires a high level of precision in curving the lens and a lens component that is clear, durable, non-toxic, and non-irritant.
These manufacturing requirements are not always easily met.
In addition, the cornea is a living membrane which continuously reshapes its curvature and thickness during the day and over time.
This renders fitting a contact lens immensely laborious.
Poor fitting can produce irregular astigmatism and other tvariations of corneal damage.
The lens material also is predisposed to sets up conditions for dryness.
Soft contacts contain significant quantities of water.
Ironically, as its water evaporates while the lens is lodged in your eye, the lens water can cause the eye's own lubricants to evaporate along with it.
Rigid contact lenses are made of plastic material that forces back water.
In both cases, the lens itself contributes to the conditions for dry eye syndrome.
The contact lens may also chafe the eye surface.
They can capture dust particles or bacteria, which migrate under the lens, provoking inflammation and infection.
Problems due to Inadequate Hygiene A very widespread disorder bothering contact lens wearers is giant papillary conjunctivitis (GPC).
This disorder causes itching, redness, filmy vision, excessive mucous flow, and even little balls of swollen tissue on the margin of the upper eyelid.
GPC, contact dermatitis and other allergic reactions in the eye are likely to happen when proteins and fats are allowed overlay the lens.
These substances come from a variety of sources, such as make-up and ingredients (such as thimerosal) found in lens-care solutions.
In the case of make-up, the cosmetics may not necessarily be those applied to the eye area itself but to the hair, face, or even the fingernails.
A very frequent irritant is the emulsifier found in water-based mascara (such as sodium borate and ammonium), which can irritate the inner lining of the eyelid (conjunctiva).
Other frequent contributors of allergenic compounds are fragrance ingredients, preservatives and emulsifiers in various cosmetic products, as well as antibiotics and corticosteroids in topical medications.
To help prevent GPC and allergic reaction, carry out enzyme treatments at least weekly on the lenses, be guided by proper lens-care techniques, and use preservative-free lens care solutions.
If you use mascara, make do with anhydrous, waterproof mascara instead.
Thickening mascara and cream eye shadows are also better than lash-lengthening mascara and powder shadows (which contain pigments and fibres that easily get into the eye).
Whilst contact lenses can be very useful in vision problems and disease treatment, their use is not without risk.
It is essential to get regular advice from your physician and to practise adequate hygiene.
You can ask your physician about medication to help lubricate your eyes, such as cyclosporine combined with castor oil to promote tear production.
