Sunglasses are an important part of the accessories you use in summer or any time of the year. They help you to look fashionable and stylish and also make a pretty good style statement. But is that the only job of sunglasses? Or do they have something more to them? Here are a few reasons why sunglasses are more than just a style statement:


1. Decrease in eye problems: Generally, you use sunscreen to protect your skin from the Sun s glare. Similarly, sunglasses protect your eyes from the harmful UV rays of the sun. It is extremely important for you to protect the eyes so that the harmful UV rays cannot enter the sensitive eye tissue and harm them. If you do not use sunglasses, then you have a higher chance of damaging your eye tissue than a person who uses them regularly. Bear in mind that the strong UV rays can cause serious permanent damage to your eyes.


2. Protection from other environmental components: Not only is the sun harmful to your eyes, but also the wind can be extremely dangerous for them. Dirt, sand, dust particles can fly into your eyes even when just a breeze is blowing. On a windy day, damage can be much more. If you are wearing sunglasses when out on a windy day, they act like a shield to your eyes against the wind and the particles,which might enter your eye.


3.  Helps clear vision: It s often difficult to have a clear vision when out in the Sun. The bright sunlight doesn t give you the clarity in vision. Without protection, you will have reduced vision as the bright glare of the Sun might cause you discomfort in your eyes and limit your vision as you will have to squint in the bright light.


4. Helps prevent aging: Although it might sound a bit surprising, but wearing sunglasses actually helps in prevent aging. The bright glare of the sun causes you to squint and this causes the age lines to appear. So, if you wear sunglasses and your eyes are protected from the bright sunlight, then you will not be squinting anymore, and hence it will not cause the age lines to appear before time.


So now, before you think that sunglasses only make you look good, think again about how they actually do much more than that.

4 Reasons Why Sunglasses are More than Just a Style Statement

Ever noticed spots or strands that  float  into your line of vision. These are known as floaters. In most cases, they do not affect your vision, but can cause a lot of discomfort. Thus, in most cases they do not require treatment unless they affect your vision significantly. Floaters are more likely to stand out when looking at bright objects or something like a clear blue sky. Moving your eyes can shift the fluid in your eyes and move these floaters out of your line of sight.

Dust particles entering and irritating the eye should not be confused with floaters. Floaters can be described as flecks of a protein called collagen. These flecks can be seen when they are loosened from the back of the eye known as the vitreous. This can happen at any age but is more likely to affect people between the ages of 50 and 75. Being near sighted or suffering from cataract also increases your risk of seeing floaters. In rare cases, it can also be triggered by a disease in the eye, an injury to the eye, tumors or crystal deposits in the back of the eye.

Noticing the odd floater is not something to worry about. However, if you notice a sudden increase in the number and frequency of floaters in your eye, see flashes of light, have pain in the eyes or experience a loss of side vision, consult a doctor immediately. This could also be a sign of a more serious condition like a detached retina that requires immediate medical attention. Excessive floaters can be removed through a surgery known as a vitrectomy or laser vitreolysis. A vitrectomy involves the removal of vitreous gel from the middle of the eye and replacing it with silicone oil or a gas bubble. The surgery last 2 or 3 hours, but you may require an overnight stay in the hospital.

Laser vitreolysis is a more recent form of treatment for this condition. This pain free procedure involves the projection of a laser beam into the eye that focuses on large floaters to break them apart or vaporize them. This procedure can be performed as an outpatient and is considered safer than a vitrectomy. The form of treatment suited to a person will depend on a number of factors including their age, what the floaters look like, where they are located and the frequency of their appearance.

Eye Floaters - When Should You Consult A Doctor?

Amblyopia is commonly known as'lazy eye. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to'see' and develop binocularity, that is the ability to perceive depth (stereoacuity). This occurs in the first 8 to 10 years of life. 

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions (adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to'see' and becomes'lazy. This condition is seen in 1-4% of population.

The common causes for dissimilar images or amblyopia are:
1. Misalignment of the eyes or squint: it is the primary reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different, resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive amblyopia:
A. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5d of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
B. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation amblyopia: any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood (drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for amblyopia
For treatment of amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye'learns to see. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible, within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

About Amblyopia or Lazy Eye

Amblyopia or Lazy eye is the eye condition in which vision is reduced and cannot be corrected with glasses or contact lenses. All the images seen by the amblyopic eye are not fully acknowledged by the brain. It always affects only one eye, but may be accompanied with reduction of vision in both eyes. It can cause loss of vision, including loss of depth perception and two-eyed 3D vision. It's treatment can yield improvements at any age, but early detection can offer the best chances for a cure. Recent research has proven that lazy eye treatment can be successful in older children and adults. Comprehensive vision examinations are required for infants, toddlers, and pre-school children for the detection of lazy eye or amblyopia.

When the brain parts related with visual processing do not function properly, problems arise with such visual functions as the perception of movement, depth perception and fine detail (acuity, clear eyesight and sharp vision). Amblyopia is the most prevalent neurological defect of vision in children and adults resulting from developmental problems in the brain. Any interference with clear vision in either eye during the first six years or 'critical' period of visual and brain development can cause a lazy eye.

Constant strabismus or the constant turn of one eye in any direction, be it inward turn or crossed eye is one of common causes of amblyopia. The differences in vision or it's prescription between the two eyes leads to refractive amblyopia. Sometimes congenital disorders or a physical blockage of an eye due to trauma, drooping lids, cataract or a blocked tear duct can also lead to amblyopia. Many parents and children are not aware of any symptoms, as amblyopia usually occurs in one eye only and a lazy eye condition can exist without a noticeable eye turn. The visual acuity tests in addition to the 20/20 eye test charts and eye examination with cycloplegic drops by ophthalmologists are necessary to detect lazy eye.

Vision therapy for the eyes and brain is a highly effective non-surgical treatment for lazy eye. It is a progressive program of vision exercises customized to fit the visual needs of each patient. It is conducted at the clinic and occasionally supplemented with exercises to be done at home or workplace. It improve visual comfort, ease, and efficiency and change how a patient processes or interprets visual information. When considering treatment options, it is important to understand that lazy eye results from neurological deficit or problems in the brain and surgery for lazy eye is performed on the muscles on the outside of the eye. Most of the cases, lazy eye surgery provides cosmetic benefits and does not improve the patient's vision, hence options for vision improvement should be exhausted before eye muscle surgery is considered.
