Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:

1. Distance from the cornea
Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes. Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.

2. Difference in vision
Since the lenses of spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.

3. Ease of use
Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in rigorous physical activity. Contact lenses are free from all these hassles - they are not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles is very uncomfortable to wear during the rains or in humid weather because they fog up.

4. Infections and complications
Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect - they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.

5. Aesthetic differences
People often prefer contact lenses as they do not change the physical appearance - they help you look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Lens Vs Specs

A common headache can have a number of reasons behind it, such as defective vision, hetrophoria or convergence deficiency, etc. Now, the question arises as to how they can cause headache. Read on to know more...

Q. Why should defective vision cause headache?

To attain a perfect vision, eyes with defective vision have to make sustained extra efforts, which results in headache. Even if the refractive error is very small, it can be the cause of headache. More prolonged the working and smaller the print, higher the incidence of headache.

Q. Can this occur at all ages?

Yes, it can occur at all ages. However, with age, the resistance decreases and hence elderly people are more prone to get headache. More the use of computer, mobiles, TV or prolonged studies precipitates headache

Q What is Hetrophoria?

Normally, both eyes always remain parallel, but in some cases, eyes have slight tendency to develop minor squint, may be convergent or divergent. This is called Hetrophoria or Latent squint. Such patients have to take extra strain to keep the eyes straight

Q. What is convergence deficiency?

For reading, both eyes have to converge and if there is weakness of convergence, extra strain has to be put on the eyes, which cause headache.

Q. What is the ideal method of refraction in young patients, I,e below 40 years?

Ideal method is to dilate the pupil with Tropicasyl plus drops. This has the advantage that the doctor can see the retina and Optic Disc. This is important to exclude any involvement of brain as the cause of headache. It also relaxes accommodation and hence provides correct refraction. In cases of Hypermetropia, it is extremely essential to dilate the pupil.

Q. What is the role of Autorefractmeter (a computer) in refraction?

It is a very important instrument to provide correct refraction, but it cannot be totally relied upon. Some opticians rely on it and give wrong numbers.

Q. What is acceptance Test?

You have refracted the eyes with Autorefractmeter or Streak Retinoscope but exact power is what a patient accepts. This is very important.

Q. What is astigmatism?

There is a difference in refraction in different meridians and it is important that a cylinder number is prescribed in correct axis. This is a difficult task and needs lot of experience.

Q. Is it important to correct astigmatism?

To relieve headache and strain on the eyes, it is very important that exact cylinder is prescribed.

Q. What is the role of exact centring of Optical Lenses?

You may give correct number, but if the centre of the Optical lenses and cornea do not coincide, satisfactory results are not obtained. To dispense correct lenses is a big art and the Optician must be qualified and well experienced.

Q. Does the quality of lens affect the visual comfort?

Yes, it is important that quality of lenses should be good, preferable fibre lenses which are Ant reflect coated. Crizal coating with capability to block the UV rays are very popular.

Conclusion: Refractive errors are important cause of headache and needs proper examination of the eyes, preferably after dilating the pupil. Astigmatic error even if too small may be the cause of headache. Spectacle dispensing is an art and a patient must select proper optician. Spectacles if advised for constant use must be used constantly to get full relief.

If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided. Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others. 

List of eye diseases caused by diabetes

1. Diabetic retinopathy: when the retina's smallest blood vessels get severely damaged due to increased blood sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.

2. Cataract: fogging or clouding condition can bring this kind of condition and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day-by-day. Glared or blurred vision is the most common symptom in this regard. 

3. Glaucoma: when the eye fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others. 

4. Diabetic macular edema: this eye disease mainly occurs in the advanced stage of diabetic retinopathy. Macula is nothing, but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed. 

5. Blurry vision: though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.
