The vision may be blurred, both from any swelling of the cornea and from excess tears. Crusty buildup from excess tears may also be present. Complications
Complications are the exception rather than the rule from simple corneal abrasions. It is important that any foreign body be identified and removed, especially if containing iron as rusting will occur.Occasionally the healed epithelium may be poorly adherent to the underlying basement membrane in which case it may detach at intervals giving rise to recurrent corneal erosions. Causes
Corneal abrasions are generally a result of trauma to the surface of the eye. Common causes include being poked by a finger, walking into a tree branch, and wearing old contact lenses. A foreign body in the eye may also cause a scratch if the eye is rubbed.Injuries can also be incurred by "hard" or "soft" contact lenses that have been left in too long. Damage may result when the lenses are removed, rather than when the lens is still in contact with the eye. In addition, if the cornea becomes excessively dry, it may become more brittle and easily damaged by movement across the surface. Soft contact lens wear overnight has been extensively linked to gram negative keratitis (infection of the cornea) particularly by a bacterium known as Pseudomonas aeruginosa which forms in the eyes biofilm as a result of extended soft contact lens wear.
At a pre-conscious level, these processes influence the competition among mental representations in which some correspond to the assertive power of worry with impaired cognitive process and others to the preventive power of worry with attentional control or exhaustive vigilance. The biases determine threatening degree and nature of worry content the worrier attempts to resolve the perceived threat and the redirection of anticipations, responses and coping in such situations.There are some who respond to mental representations in an uncertain or ambiguous state in regard to the stressful or upsetting event. In this state the worrier is held in a perpetual state of worry. This is because availability of an overwhelming number(maybe 2 or 3, depending upon the worry-prone individual) of possibilities of outcomes which can be generated, it puts the worrier in a threatening crisis and they focus their attentional control voluntarily on the potential negative outcomes, whereas others engage in a constructive problem solving manner and in a benign approach rather than to engage with heightened anticipation on the possible negative outcome. Philosophical perspectives
Greek thinkers such as stoic philosopher Epictetus and Seneca advised against worry. Albert Ellis, the creator of Rational Emotive Behavior Therapy, was inspired by the Stoics’ therapeutic ideas. Religious perspectives
The biblical word used in Hebrew for worry (Hebrew: דָּאַג, daag) regards worry as a combined form of fear and sorrow which affects nephesh, the totality of our being. The bible takes a fortitude-strengthening approach regarding worrying e.g.
