Q

What is the difference between bifocal and varifocal glasses?

   

A

Varifocal and Bifocal lenses usually have distance and reading powers to correct presbyopia. Varifocal lenses allow you to see  near and far objects ( and all distances in-between)using just one pair of glasses. Unlike bifocals, there's no visible line on the surface of the lens (Bifocal lenses contain only two prescription powers in one lens). With Varifocals it doesn't matter whether you're reading a book, watching TV or driving, as you'll you only ever need one pair of glasses, making them convenient for people who would otherwise have to carry two pairs of glasses.

   

Q

Why do I need an Eye test every 2 years if everything is always fine?

   

A

Eyes don't usually let you know that something is wrong. Any change is usually very gradual, so you become accustomed to the change in your vision. Therefore, regular eye tests are important to pick up any change as soon as possible to make sure any problem can be treated before it affects vision. The eye test detects many conditions earlier than waiting for symptoms to appear. The eye test does not just check whether you need glasses, but it can show a number of underlying health problems, such as diabetes and glaucoma, and the general condition of your eyes.

   

Q

How old does my child have to be before they can have their eyes tested?

   

A

Children can be tested at any age. It is recommended that an optometrist sees them before they start school and start learning to read. Often, vision problems can be the reason why a child does not perform well at school, for example because they cannot see the board. The earlier a problem is detected the more chance there is of successful treatment. Children's eyes are fully developed by the time they are 8 years old so it is very important to have any problems detected before this.

   

Q

If the eyes do not seem to be working together perfectly, which you will notice when they are looking at an object, which can indicate a squint

   

A

During the first year there are rapid changes in vision in each eye. Do not worry if your baby cannot seem to focus or their eyes seem to wander during the first 4 months. Signs that need checking by your doctor or Optometrist are - persistent eye infections (although in babies the tear ducts are not fully open for the first few months)

   

Q

Why is an Eye test so important?

   

A

Your eyes cannot be replaced. You will not necessarily have any symptoms or pain. The eye test can pick up very early signs of any problems the earlier treated the better. The eye test can detect underlying health problems that you aren't aware of, such as Diabetes, High Blood Pressure, some brain tumours and multiple sclerosis. The eye test will detect if your vision can be improved. You may just be used to seeing less clearly so don't realise it can be improved upon. Good Vision gives a better quality of life. For children, it is essential that their eyes are functioning normally for them to perform well at school. Don't accept that poor vision is due to your age. It may be possible to improve it further. It is important your vision meets certain legal standards for driving and certain occupations..
