Changes in your lenses in your eyes cause light entering the eye to be scattered rather than focused precisely on the retina. This creates more glare. Changes in color perception. The normally clear lens located inside your eye may start to discolor. This makes it harder to see and distinguish between certain color shades. Reduced tear production. With age, the tear glands in your eyes will produce fewer tears. This is particularly true for women experiencing hormone changes.

Encountering problems with near vision after 40 If you have never needed eyeglasses or contact lenses to correct distance vision, then experiencing near vision problems after age 40 can be concerning and frustrating.

The following symptoms could be the early warning signs of a serious eye health problem: Fluctuating vision. Frequent changes in how clearly you can see maybe a sign of diabetes or hypertension high blood pressure. These chronic conditions can damage the tiny blood vessels in the retina, the light-sensitive layer at the back of the eye.
This vision loss can sometimes be permanent. Seeing floaters and flashes. Occasionally, you may see spots or floaters in your eyes. In most cases, these are shadowy images of particles floating in the fluid that fills the inside of the eye.
Although they can be bothersome, spots and floaters typically don't harm vision. They are a natural part of the eye's aging process. Presbyopia is the age-related loss of flexibility in the lens of your eye.
Another age-related eye issue, cataracts occur when proteins break down in the lens of your eye, creating a cloudy lens and blurry vision. Cataracts are an extremely common vision issue and cataract surgery is one of the most frequently performed surgeries in the world. Glaucoma involves the buildup of fluid in the anterior chamber of the eye. Unable to drain properly, this fluid creates increased eye pressure and eventually damage to your optic nerves, which in turn can lead to blindness. Presbyopia, cataracts, and glaucoma are by far the most common eye problems and diseases patients over 40 should watch out for.
Additional yet less common eye problems include macular degeneration , diabetic retinopathy , and keratoconus. Suddenly worsening vision is almost always an indicator of an underlying serious condition. These conditions range from stroke to brain inflammation to acute angle-closure glaucoma. While there is no guarantee that a sudden change in vision will cause blindness, ignoring sudden vision changes highly increases the likelihood that you will go blind.
We cannot stress this enough: If you experience rapid changes in vision quality, see a doctor as soon as possible. Vision improves without medical treatment only in extremely rare cases, most of which involve young children whose eyes were still developing. There are some who believe that certain eye exercises, massages, and diets can improve vision over time, but these assertions have yet to hold water in clinical tests. As noted above, there are also many current procedures that address vision loss due to cataracts, presbyopia, glaucoma, and more.

Eye disorders — focusing problems Problems with focusing refractive errors are the most common eye disorders.
These occur when the image of what you are looking at does not focus precisely on the back of the eye retina and appears blurry. The main types of refractive errors are myopia short-sightedness , hyperopia or hypermetropia long-sightedness , astigmatism and presbyopia inability to focus on near objects. Refractive errors occur when there is a mismatch between the length of the eye and its optical power.
These mismatches usually originate during childhood and are thought to be affected by both hereditary and environmental influences. Myopia short-sightedness People who have myopia short-sightedness do not see distant objects clearly. In a normal eye, the lens and cornea focus light into an image on the retina.
In a myopic eye, the light is focused in front of the retina and so the image is blurred. Myopia is a very common condition that affects about 15 per cent of the population.
Usually, myopia begins to develop in teenage years, although it can happen any time from birth. Myopia may progressively increase over the following few years, slowing in the mid to late twenties in most people. Some clues that may lead you to suspect myopia in a child are: screwing up of eyes or squinting to see distant objects difficulty reading the blackboard at school sitting very close to the television poor posture while reading a lack of interest in playing outdoor games.
Treatment for myopia There is no cure for myopia. However, glasses or contact lenses can help you see clearly. There are several techniques available to correct myopia by reshaping the cornea to reduce its power. These include laser surgery, which removes tissue from the cornea, leaving it with a flatter surface. High levels of myopia can cause more serious problems, such as stretching and thinning of the retina, holes and tears, and the risk of retinal detachments. If you are myopic, you should have regular eye examinations and talk to your optometrist about the potential for problems.
