THE MAJOR EYE EFFECTS, THE CAUSES AND PREVENTIONS.
Your doctor may refer you to a specialist, such as an optometrist or ophthalmologist, to determine what’s bothering your eyes. The specialist will usually conduct a thorough examination of your eyes. They will likely measure the volume of your tears. They may also measure how quickly your tears evaporate from the surface of your eye.
If the aqueous can access the drainage angle, the glaucoma is known as open angle glaucoma. If the drainage angle is blocked and the aqueous cannot reach it, the glaucoma is known as narrow angle glaucoma.
If direct flash must be used, a good rule of thumb is to separate the flash from the lens by 1/20 of the distance of the camera to the subject. For example, if the subject is 2 meters (6 feet) away, the flash head should be at least 10 cm (4 inches) away from the lens.
You probably won’t need to see a doctor for dry eyes. But if you do, your doctor may prescribe medications, such as ophthalmic cyclosporine eye drops (Restatis) or topical corticosteroids.
Professional photographers prefer to use ambient light or indirect flash, as the red-eye reduction system does not always prevent red eyes — for example, if people look away during the pre-flash. In addition, people do not look natural with small pupils, and direct lighting from close to the camera lens is considered to produce unflattering photographs.
There are two main groups of artificial tears: those with preservatives and those without. Eye drops with preservatives are the more common type. These usually come in a multi-dose bottle. They contain chemicals that prevent bacterial growth in the open container. However, some people find the preservatives irritate their eyes. Eye drops without preservatives come in small, single-dose vials. They are less likely to irritate your eyes. They may, however, be more expensive.
If you have a cataract, there is a cloudy area in the lens of your eye that results in the inability to focus light, and your vision is impaired. Symptoms of this eye problem in diabetes include blurred or glared vision.
Dry eyes occur when your eyes don’t produce enough tears, or they produce tears that can’t effectively keep your eyes moist. Tears are needed to help keep enough moisture in your eyes. They keep your eye surfaces smooth, wash away foreign materials, and also help protect your eyes from infection.

When diagnosed and treated early, eyelid cancers usually respond well to surgery and follow-up care, with the eye and eyelid largely retaining normal function. With reconstruction, they generally remain cosmetically attractive. But left untreated, they are extremely dangerous and may even ultimately penetrate the brain. Watch for these early warning signs:
Normally, the lens at the front of your eye is clear, allowing light to pass as easily as through a window. A cataract causes the lens to grow cloudy. This makes your vision blurry and affects the way you see light.
Benign growths of the conjunctiva: Problems with the conjunctiva, the protective membrane covering the outside of the eye and the inside of the eyelids, usually develop later in life. Pterygia, fleshy benign growths on the conjunctiva that may ultimately interfere with vision, may require surgical removal. These unsightly growths most frequently occur in areas where UV is intense year-round.
