What is Squint Eye?


What is Squint?

Squint is a misalignment of the two eyes so that both the eyes are not looking in the same


direction. This misalignment may be constant, being present throughout the day, or it may 

appear sometimes and the rest of the time the eyes may be straight. 




It is a common condition among children. It may also occur in adults.


Squint Eye - Exotropia

When the eyes are not aligned properly, each of the eyes is focusing on a different object 





and sends signal to the brain.



A squint may be classified and described in different ways. For example:

-> An eye that turns inwards is called an esotropia.



-> An eye that turns outwards is called an exotropia.


-> An eye that turns upwards is called a hypertropia.


-> An eye that turns downwards is called a hypotropia.

Contact Lens - Their Features & Their Use


Contact Lens
Contact lenses are small visual devices made with curved pieces of plastic shaped in a way to conform directly to the wearer’s eye. They provide an artificial refracting surface to the human eye and are used to correct vision problems like myopia and hypermetropia. Contact lenses aid in eye focusing in the same manner as spectacles do. Apart from these corrective measures, contact lenses can also be used for cosmetic and therapeutic reasons.


Features of Contact Lenses
The lenses are made from different types of materials – soft and rigid – and come in a variety of designs and colors. These include disposable, colored, astigmatic, aphakic, presbyopic and keratoconic lenses. The initial fitting and follow up care are important parts of contact lens usage to give maximum benefits of vision, appearance, comfort and tissue integrity.

Advantages of Contact Lenses
Contact lenses are capable of correcting most of the problems that spectacles can as well as some additional ones that glasses cannot.
People not satisfied with their appearance using glasses can opt to use contact lenses for improved appearance. Contact lenses are not in the danger of slipping off, getting wet, or fogging up, which can easily happen with spectacles.

Uses of Contact Lens
The primary use of contact lenses is to correct myopia (short sightedness). They can also be used to rectify hyperopia, astigmatism, presbyopia and aphakia. Rigid lenses are used to correct irregular corneal trauma. Soft lenses are used as bandages for conditions like bullous keratopathy, recurring corneal erosion as well as to increase comfort, vision and postoperative wound healing.

The Adverse Effects of Contact Lenses
People have difficulty in using contact lenses if they have eye irritations due to allergies or dust and chemicals. Overactive thyroid gland, severe diabetes or extreme arthritis in the hands, dry eyes related to pregnancy, contraceptives, diuretics, antihistamines and decongestants and eye disease prevents a person form using contact lenses.
The usage of contact lenses may give rise to problems like eye infections, allergic reactions to lens care solutions and deposit on lenses, redness of the eyes, scratched corneas, alteration in corneal shape and structure and abnormal blood vessels growing in the apparently clear cornea. You should consult your eye specialist without delay if there is burning, extreme sensitivity or hazy vision or pain.

Can I Use Eye Drops With My Contact Lenses?


Yes. Certain eye drops can be used with contact lenses. Most over-the-counter eye drops are divided into three categories: “dry eye" eye drops, “get the red out” eye drops and “contact lens” eye drops.
  • "Dry eye" eye drops:

    Dry eye drops come in a variety of formulations. Some are thicker than others and may actually cloud your vision or “gum up” your contact lenses. While some of them may be okay for use with contact lenses, they are designed to not only lubricate the eye, but to promote healing of the eye’s surface.
  • “Get the red out” eye drops:

    "Get the red out" drops have special ingredients called vasoconstrictors. These drops shrink the tiny blood vessels in the conjunctiva, the clear tissue that coats the white part of your eye. These eye drops could cause deposits to form of the surface of your contact lenses and if used repetitively to re-wet your contact lenses, could cause “rebound” redness. Rebound redness occurs when the vasoconstrictor wears off. The blood vessels dilate larger, causing the eyes to appear bloodshot. This may cause dependency or mask underlying infections or inflammations.
  • "Contact lens" eye drops:

    Contact lens eye drops are often called re-wetting drops. Re-wetting drops lubricate your eye and hydrate the contact lens, making your eyes more comfortable while wearing your contact lenses. Theses eye drops are labeled “For use with soft contact lenses,” and are usually located next to contact lens cleaning solutions in the store. Eye care professionals usually encourage frequent use of re-wetting drops, as it improves comfort and helps clear out debris underneath your contact lenses.
  • Talk to your eye doctor if you are taking any eye drops for medical eye problems, such as glaucoma. Ask your eye doctor for the best way to insert eye drops and whether or not contact lenses should be worn while taking your medication.

What type of Sunglasses You Choose?

Take a cue from celebs and fashion types who know that the right pair of sunglasses can add instant mystique, chic and polish to any look.

But also know that sunglasses are more than just a fashion statement: they are a necessity to protect your eyes from harmful UV rays.
Protection
The color and degree of darkness of a lens doesn't tell you anything about sunglasses' ability to block UV rays which can harm your eyes, according to the American Academy of Opthalmology.
Look for sunglasses that block at least 99% of harmful UV rays (check the label!).
Lens
A sunglass lens can be made of glass or plastic and can have special hi-tech treatments.
  • Mirrored - Thin layer of metallic applied to lens that may reduce visible light to reach eyes, but not UV rays according to AAO.
  • Gradient - A tinted lens that is darker on the top fading to no tint on the bottom
  • Polarized - Cuts the glare from smooth surfaces such as water, snow or pavement.
  • Photo chromic - These lenses are sun-sensitive and transition from light to dark shade according to light conditions.
  • Tints - A color called neutral density gray will shade but not change your color perception, according to Dr. Bert Dubow on AllAboutVision.com.
Styles
Sunglass trends have taken their cue from runway and street fashion. Retro looks like aviators and oversized, "Jackie O" frames along with sleek, futuristic shield shapes compliment what's going on in fashion.
Trendy tints span the rainbow, so look for a hue that flatters your coloring.
  • Wraps - Extending past the eye to the temple, this style "wraps" around the face.
  • Shields - One-piece shields have a modern look and are often partially rimmed or rimless and come in a wide range of tints.
  • Aviators - Shaped like a teardrop, metal-rimmed aviators have enjoyed waves of trendiness since WWII when pilots favored this style.
  • Clip-ons - An easy way to convert prescription eyeglasses to sunwear, clip-on shades can attach with either clips or magnets.
Flatter Your Face
In general, you should choose a pair of shades in a shape that is the opposite of your face shape.

For example, round faces look best in anything but round shades. A rounder face can carry off geometric shapes, ovals, wraps and shields.

More angular or thin faces look better in rounder frames; oval faces can carry off almost any style.

What Are Polarized Sunglasses?


Many people don't understand the importance of wearing polarized sunglasses when they are enjoying the outdoors.
 
Your favourite activity may be biking, climbing, surfing, volleyball, baseball, jet-skiing, snowboarding or fishing, the bottom line is that you need to understand the importance of polarized sun glasses and what they can offer you.

The biggest thing that polarized sun glasses offer is the ability to cut through the glare created by the sun, when it bounces off of reflective surfaces such as roads, snow, and water.

This might not sound like a big deal but it's most certainly true. Many times we're so used to seeing and dealing with this glare, that we can't imagine it not being there. Quality polarized sunglasses cut through this glare not only enabling us to see better, but also protecting our eyes from the nasty UV rays within the glare.

Nowhere is the effect of polarization seen more than by anglers, especially anglers that stand in the flowing water of a river or stream. With the help of quality polarized glasses, angler can actually see into the water, and spot not only fish, but also underwater debris.

The effects of wearing quality polarized glasses is also extremely helpful to anyone who spends time on snow covered mountains skiing or snowboarding. The glare created by the sun bouncing off of snow can be very dramatic, and a quality pair of polarized glasses will cut through this glare.



If you spend any time in the outdoors, you need to invest in a quality pair of polarized glasses. When it's all said and done, you'll be glad you did. Not only that, but your eyes will as well.
