Recommendations from our optometrists
Can you not see items close to you as well as you used to?
After the age of 40 many people experience problems with their vision. A condition called presbyopia causes the lens in our eye to lose its elasticity along with the reduction in strength and endurance of the muscles that mobilise the lens.
Is this familiar?
- You are unable to read small print as well as you used to
- You feel like your arms are not long enough because you want to place the text as far from your eyes as possible.
- You are experiencing difficulties with reading in dim light, you need a brighter light to read than before.
- Your eyes tire quicker and you experience redness of your eyes.
- You experience headaches
With symptoms like these you should turn to an optometrist or ophthalmologist who will check your vision and will prescribe you spectacles if found necessary.
Do you use computers often?
Individuals who use computers for prolonged periods daily experience a wide variety of symptoms: tired eyes, redness of eyes, dryness, tingling, lachrymation, headaches, trouble with focusing on text after prolonged reading or blurred vision when looking into the distance after looking at something up close.
These symptoms indicate that your eyes are overworked and need rest.
Before turning to an eye care physician you should try the following:
- Analyse you work space (ergonomics, lighting, humidity etc.)
- When working with computers take frequent breaks. Look out the window into the distance to towards the far corner of the room.
- Blink more often. If you do not blink enough Your eyes tend to dry and tire out. You may experience headaches, tingling of your eyes or blurred vision. With symptoms like these you may want to use eye drops (artificial tears). More detailed advice can be given by an ophthalmologist or pharmacist.
- To avoid Your eyes from getting tired perform appropriate exercises found here.
If your main concern is focusing you sight (into the distance or something close to you) the cause may be overworked visual muscles or ametropia which is an impaired vision. In this case eye exercises and spectacles with a slight positive lens. The cause of the problems has to be determined by an optometrist or ophthalmologist.
If you are experiencing the above mentioned symptoms and you are short sighted you could try using spectacles with a smaller negative when working with a computer or glasses with a progressive lens (e.g. Hoya Nulux Active, Essilor Anti-Fatigue) when looking straight your long distance vision will not be affected.
If you have been prescribed reading glasses you may feel like they are too powerful to view a computer screen. This is because reading glasses are supposed to support your vision 33 cm – 40 cm but the computer screen is often further than that. In this case you may want to consider spectacles designed for computer use (e.g Hoya Addpower, Essilor InterView ). These glasses have a lower part that supports reading, however the top part is less invasive so viewing the screen is more comfortable.
