The lids consist of movable tissue. Inside they are coated by a smooth, delicate tissue-membrane which, if traced up and down, forms a fold coming back on itself and then enveloping the eye, but stopping at the edge of the cornea. This fine membrane is called the conjunctiva. Thus the inside of the lid and the surface of the eye are in direct contact, more so when the lids are closed and the cornea itself is covered. Sometimes this membrane becomes subject to a mild infection, of a non-specific type, and the result is conjunctivitis. This is not usually a serious condition, and is easily treated either with drops or by bathing the eye in a prepared solution. The symptoms are irritability, discharge, redness, particularly along the top edge of the lower lid, and occasionally swelling. Most people will experience conjunctivitis at least once in their lives. Some have more than one attack each year. People who wear contact lenses are more prone, since the daily routine of placing lenses on the eye offers a greater opportunity for an infective organism or irritant chemical to reach the eye.

Objective measurement means the use of instruments, while subjective measurement requires you to state an opinion. In ordinary practice the practitioner will use both methods, and thereby establish a pattern which enables him to prescribe the right optical correction. If you repeatedly give a wrong answer to a subjective inquiry the experienced occulist will proceed to further objective (optometrical) tests. Read the rest of this entry »

The symptoms of eye-strain are diverse and confusing. Inability to use the eyes for a specific task leads to frustration in most intelligent people, regardless of whether such inability is temporary or permanent. There are states where the individual finds that, by squeezing the eyes, or by holding objects at abnormal distances, better vision is possible, but this only leads to fatigue and congestion of the delicate musculature.
