What Should be Considered When You Choose Contact Lenses
What should be considered when you choose contact lenses ?
When you are choosing contact lenses,many factors should be considered including your lifestyle,health,astigmatism,corneal curvature,allergies,dry eyes,hygiene,previous over-wear,frequency of use and so on.
Seeing your Optometrist will help you determine the best type of contact lenses for your eyes.
1. A Good Eye Health?
Before you decide to wear contact lenses,you should cheak for your eye health.You can wear only if you have a good health.The healthiest type of lens is the daily disposable soft lens. These lenses are always sterile when inserted into the eyes as they are never kept overnight. This means that no dirt, bugs or tear proteins can accumulate which all have the potential to cause problems. Fortnightly and Monthly disposables are also available which still require daily cleaning and overnight storage with contact lens solutions.
2. Have Astigmatism?
Normally,your eye is shape like a tennis ball.But with astigmatism,your eye is not perfectly round like a tennis ball.At a certain level of astigmatism the contact lens prescription needs to be “tailor-made” in order for you to see clearly. Lenses that cater to astigmatism are called Torics and are available in both rigid and soft form.
It is often possible to fit a normal rigid contact lens and correct the problem without the need for a Toric with lower levels of astigmatism.If you have mainly short or long-sight with very little astigmatism, a normal soft contact lens is generally fine for you just.
3.What are lifestyle?
Your lifestyle often determines your the requirements of sight correction, which in turn influences the type of contact lens suitable.And if you may work in an office and use the computer all day, for which you wear spectacles; perhaps you play golf, or football once per week and find that your spectacles “steam up”?A limited supply of daily disposables just for sport would be your best option rather than monthly disposables, which require cleaning and will not be used often enough to make them worthwhile.
If you are a rugby player and require good side vision in order to perform optimally, full-time contact lens wear is probably your wisest option.
Frequent jet-setters may prefer spectacles as contact lenses inevitably dry out whilst flying. Whatever your lifestyle, your optometrist will prescribe contact lenses tailored to your needs
4.Have Any Allergies?
Hayfever, eczema or asthma sufferers may find contact lenses more uncomfortable than most people. Allergies can create an over-sensitized eye, rendering increased lens awareness. Also, the eye reacts to dirt and proteins on the lens much more and may cause the upper eyelid to develop bumps. This is called contact lens related papillary Conjunctivitis. The best solution for those with severe allergies is to wear lenses infrequently (up to 3 times/week) and to use daily disposables. If your lifestyle requires you to use lenses constantly, then disposables are still the best option. Occasionally some individuals are allergic to a certain lens material or a certain lens solution.
5.With Dry Eyes?
If you suffer from chronic dry, smarting eyes. It may cause increased lens awareness after some hours of lens wear. Your optometrist will prescribe an alternative lens with a different water content, fitting or material, in order to improve the comfort. Preservative-free contact lens comfort drops are also advised.
6.Your Frequency Of Use.
Are you only wish to use contact lenses for a sporting activity once per week? If you are,a daily disposable will be most suitable from both a health and cost perspective. Rigid lenses are not recommended as they need to be used most days in order to achieve best comfort. Those who wear their lenses sporadically may wish to consider fortnightly or monthly disposables. Your optometrist will be able to discuss the various options most suited to your requirements.
7.Your Previous Over-wear
If you have previously over-worn your contact lenses, your eyes will need more oxygen.So you may be told to use a higher water content, or higher Dk, lens.Because it may be a soft or rigid lens.? Remember to give your eyes a break and use your spectacles one day per week.Just remember.
8.Other factors
Such as corneal curvature,hygiene and so on to be considered.
